– replace the seal under the hopper flap
– replace the seal with the charging hopper
– replace the gasket
– replace the gasket
– tighten all screws

Indicates that the boiler exchanger may be dirty. Flue gas temperature higher than 280 ° C.

Explanation:

Clean the boiler exchanger. Reduce fuel supply.

Anti-blocking is a function that works with pellets.

Explanation:

It serves to keep the heat in the furnace. When the boiler turns off, it reaches the set temperature every 20 minutes, if the temperature does not drop, the anti-blocking function will be activated for 5-10 seconds. The anti-blockage can be set freely according to the needs and power of the boiler. Normally it is 5 seconds.

Domestic hot water priority is a function in the controller that first heats the domestic hot water tank, and then turns on the central heating.

Explanation:

Function normally used in places with very high domestic water consumption.

The PLATINUM controller has three operating modes.

Explanation:

Summer – that is, heating only domestic hot water.
Manual – that is heating the central tap water and central heating. In the operating mode, the preset temperature must be set on the boiler and on the heating circuit.
Weather – that is, heating the central tap water and central heating. In this mode, it is the weather station that calculates the set temperature for the boiler and the heating circuit.

It carries out:
– automatic ignition and extinguishing
– weather controls
– room control (room temperature)
– control of the central utility water pump
– clock control: circulation pump, additional pump, burner (boiler operation time)
– control by means of the LAMBDA PROBE

Domestic hot water disinfection is a function in the controller that heats the domestic hot water tank to a temperature of 70 ° C in order to disinfect it.

Explanation:

A function to kill the Lagionelia bacteria in the central tap water circuit. Normally it is rarely used. If the temperature in the tank is kept at 50 ° C, such bacteria will not breed. The probability of bacteria occurrence is when we keep the temperature in the tank low or when we rarely open the water taps.

The heating curve is a graph of external temperatures to the temperature of the central heating water. The heating curve is a calculated heating temperature in relation to the outdoor temperature.

Explanation:

The heating curve diagram is included in the controller manual.

The boiler protects against freezing by the controller’s program, which prevents this from happening.

Explanation:

At a temperature below 8 ° C, the controller opens the mixing valve and turns on the central heating pump in order to prevent the water from freezing in the system. Additionally, all pipes particularly exposed to heat loss should be protected with additional insulation. Check that there are no broken windows, open windows, holes in the walls, etc. near the pipes.

Don’t panic. Usually, when we boil water in the boiler, nothing serious should happen. The reason for the boiler to boil is the lack of heat reception, open ash-pan door, placing easily flammable fuel, e.g. newspapers.

Explanation:

In such a case, the controller turns on all pumps above the temperature of 90 ° C, even if they are turned off, and opens the mixing valve to cool the boiler down.
If the door is open, close it. If it is an upper combustion boiler, you can open the top door in order to cool the boiler faster.
It is absolutely forbidden to allow cold water into the installation – it may cause the boiler to explode.

The higher the better, but the minimum boiler temperature should not be lower than 60 ° C.

Explanation:

The boiler should be adjusted in such a way that at the boiler temperature of 60oC, the flue gases are approx. 140 ° C.
We will have the best boiler efficiency.
All combustion conditions will be maintained.
At such temperatures, the boiler will not freeze, it will not get wet due to the lack of flue gas condensation (dew point temperature).

DHW priority is enabled. Schedule is attached.

Explanation:

In order to eliminate the problem, turn off the DHW priority and set the schedule.

It is forbidden to allow water to enter the system while the boiler is in operation.

Explanation:

Supplying water to the hot boiler may cause the boiler and installation to become unsealed.
When the boiler is very hot, it may lead to leakage or cracks.

As a book, the minimum return temperature is 10 ° C less than the flow temperature.

Explanation:

In practice, it is practically impossible without the use of mixing valves or other methods of mixing the boiler.
It is advisable to install a four-way valve, with such an installation, the boiler operates on a short circuit at high temperature, and the installation at any set temperature.
The return protection at this temperature is maintained and it can be said that it is equal to the boiler flow temperature.

Too low return temperature, allow the boiler to slowly allow water into the central heating system, in the case of a long-term condition, place the return sensor closer to the mixing valve or change the minimum return temperature.

Unburned eco-pea coal falls into the ash pan because the feeding of eco-pea coal is set too high.

Explanation:

Reduce the feed by 2-3% and watch for improvement.

Pellets can be used to burn in boilers with a gutter feeder.

Explanation:

Pellets with a granulation of Φ 6-8 mm

Sintering on the burner is formed when the air supply is set too high.

Explanation:

Reduce the blower power.

Bad fuel combustion in boilers with an automatic feeder results from wrong selection of feeding times. The blower settings are wrong.

Explanation:

Adjust fuel delivery and / or blower (see settings table). Call the service.

In the retort burner, the fuel burns only on one side of the furnace due to the dirty air chamber of the burner. There is no seal under the retort flange or the fan is dirty.

Explanation:

Clean the burner air chamber. Fit the packing cord. Clean the fan.

The reason for breaking the split pin is the fuel granulation inconsistent with the manufacturer’s recommendations, (a lot of stones in eco-pea coal or a lot of sawdust in the pellets), wet fuel, sinter on the burner.

Explanation:

Replace eco-pea coal.
Sift eco-pea coal, replace.
Replace the pellets.
Dry the fuel.
Clean the burner.

The feeder engine is running, but it does not feed fuel because the split pin is broken or the feeder screw is worn.

Explanation:

Replace the split pin. Replace the feeder auger.

The blower does not work because the plug may be unplugged. The boiler was overheated, the STB protection was activated.

Explanation:

Insert the plug from the blower into the socket. After the boiler has cooled down, press the STB button.

The feeder motor heats up due to the used capacitor.

Explanation:

Replace the capacitor.

The feeder does not work and the engine hums because it is probably blocked, but the pin has not been broken. The motor capacitor may also be worn out.

Explanation:

Open the cleanout window, remove the “foreign body”, eg a stone. Replace the motor capacitor.

In order to avoid flashback, the controller activates the feeder in order to push the fuel out of the feeder pipe.

The maximum feeder temperature is 80 ° C.

Fuel is burned too quickly due to:
– too large chimney cross-section
– too much air supply
– wrong driver settings

Explanation:

Close the throttle on the flue. Check the door tightness. Adjust the air supply. Adjust the controller or call the service.

During the first start-ups, the boiler “sweats” as condensation occurs.

Explanation:

Fire up the boiler to the temperature of about 80oC and keep it for at least 6 hours. When there is a need, we repeat this action.

There is no definite answer to this question. It can be assumed that a full tank of fuel will last for 3-4 days.

Explanation:

The burning behavior of the boiler depends on:
– calorific value of fuel
– the degree of thermal insulation of the building
– type of installation: underfloor heating, radiators, boiler
– cleanliness in the boiler exchanger, ash content in the ash pan
– outside temperature
– house temperatures
– combustion quality

Smoke comes out of the boiler door due to lack of draft.

Explanation:

Wall tightly the entrance of the flue to the chimney. Check the chimney patency and its parameters, if they comply with the recommendations.
Seal the outlet of the stove to the chimney, preventing the intake of cold air. If the chimney cross-section is too small, an exhaust fan can be installed.

There are a few cases where the boiler is greasy, e.g. wet fuel, bad combustion conditions, oversized boiler, low boiler temperature.

Explanation:

Seal the entrance to the chimney tightly.
In the first case, the moist fuel produces too low exhaust gas temperature and thus exhaust gas condensation. In this case, not only is the boiler greasy, but also the chimney.
In the latter case, most often there is simply not enough air in the combustion chamber. Just add some air and a flame, the gases will burn freely without precipitating carbon from the exhaust.
In the case of an oversized boiler, the temperature is obtained very quickly and therefore the boiler will be at standstill more often than not in operation. As a result, the gases in the flue gases will not burn out, i.e. the boiler will become greasy.
Too low boiler temperature is the worst error. If the boiler is incorrectly connected to the installation, it is the thermostat in the house, i.e. to reduce the temperature in the house, you need to lower the boiler temperature. In this case it is recommended to install mixing valves.

– the fuse of the gearmotor has blown
– the clutch of the worm and the gear motor is disengaged
– uncleaned screw before the end of the boiler operation

Explanation:

– check and replace if necessary
– replace the clutch insert and reattach the clutch
– remove the auger, clean it, notify the manufacturer

There is a leak in the entire system.

Explanation:

Check if the feeder flap is properly closed. Check seals and screws of the feeder with the burner, if necessary, tighten any loose elements.

– the overload relay has tripped
– no fuel in the hopper or fuel has hung over the feeder
– the clutch of the worm and the gear motor is disengaged

Explanation:

– reset the overload relay
– check the fuel level in the container and above the fuel pickup openings
– replace the clutch insert and reattach the clutch

– gearmotor bracket unstably attached to the ground
– wrong centering of the gearmotor bracket in relation to the worm

Explanation:

– improve and ensure permanent fixation
– check alignment of assembly and center if necessary

Incorrect combustion regulation.

Explanation:

Adjust the correct combustion in the boiler in accordance with the boiler manual.

– no fuel – check the tank and the feeder for clogging
– too low starting dose – check the starting dose
– damaged igniter – check the heater
– damaged drive motor – check the motor thermal

The photosensors in the burner should be cleaned periodically with a damp, soft cloth. To do this, disassemble the housing by loosening four mushroom head screws in REVO Mini – REVO Mini35 models, and three bolts in models from REVO 44 to REVO 150. Then remove the photosensor from the socket, clean it and reinstall it. After performing the above steps, reassemble the burner housing in reverse order.
Photosensor cleaning frequency: boiler rooms every 3 months
Measurement reading in the dark 0-5 units, in full light 100 units.

The most common cause of a defect is the destruction of the thermoprotection of the sensor, which in turn leads to overheating of the measuring element. If, despite the burner cooling down, the fault cannot be canceled, the measuring sensor must be replaced. In order to verify whether the sensor is definitely damaged, measure its resistance, which should be between 1-5 Ω. The resistance of a damaged sensor is about 100 kΩ.

– blockage of the blower blades – unscrew the blower cover screws and check whether they are not mechanically blocked
– check the voltage on the blower wires
– check the blower motor capacitor

– if the DHW tank is not being loaded at this time and the preset DHW temperature has been set above the preset boiler temperature, if so, then the difference in indications will disappear after heating the DHW tank or reduce the preset DHW temperature
– whether the time periods are turned on – turn off the time periods

– check that the feeder wires are properly connected to the terminals
– check if the jumper is on terminals 1-2 of the B module
– check whether the feeder motor is not damaged
– if you can hear the engine running and the fuel is not fed, check the feeder in accordance with the feeder’s manual

Check the power modulation settings in menu → boiler settings → power modulation.

Increase the value of the parameter Extend HUW pump operation time in order to cool down the boiler.

The reason may be loading the HUW container with activated HUW priority. Wait until HUW is loaded or disable HUW priority.
The reason may be that the SUMMER function is active.
The reason may be activation of the return protection function (menu → service settings → boiler settings → return protection). If the return protection function is enabled – check that the boiler water return sensor is thermally insulated from the environment. Improve the thermal contact of the sensor with the pipe by applying thermal paste. Increase the preset boiler temperature in order to provide a power reserve for heating return water. Check if the hydraulic system is properly made, i.e. after closing the valve, the return temperature must rise above the value of the Min. Return temperature parameter.
The reason may be the ongoing calibration of the mixer valve, wait until the calibration is completed. Active calibration is marked with the word “CAL” in the INFORMATION menu.

– too high starting dose – check the starting dose
– dirty or faulty photosensor – clean or replace photosensor,
– faulty external thermostat in oil boilers or baking ovens

– burner dirty with trail
– low chimney draft – use a fume extractor

– whether the mains fuses are blown and replace if necessary
– whether the cable connecting the panel with the executive module is properly connected and whether it is not damaged

The internal feeder is designed to evenly mix and feed fuel. The reason for the clogging of the internal feeder may be:
– wrong setting of the internal feeder in relation to the external feeder – increase the working time of the internal feeder (service menu / burner feeder)
– damage to the gear motor – replacement of the gear motor
– incorrectly selected feeder operation interval – the value should not exceed 20s. (service menu / burner interval)

– whether the boiler exceeded the temperature above the central heating pump activation temperature parameter – wait or reduce the value of this parameter
– whether the DHW priority that blocks the CH pump is enabled – disable the priority by setting the DHW pump operation mode to No priority
– whether the central heating pump is damaged or blocked

Check if the safety temperature limiter STB input jumper is on terminals 1-2, (the jumper should be installed only if the temperature limiter is not connected).
If the boiler manufacturer has equipped the boiler with an STB temperature limiter with manual return to the starting position, it should be unlocked by unscrewing the cover and pressing the button according to the manufacturer’s documentation.
Check the fan and replace if necessary.

– check that the feeder wires are properly connected to the terminals
– if the STB temperature limiter is connected to terminals 1-2, check whether the circuit has not been cut off due to boiler overheating
– check whether the feeder motor is not damaged
– if you can hear the engine running and the fuel is not fed, check the feeder in accordance with the boiler manual

– check if there is good thermal contact between the temperature sensor and the measured surface
– that the sensor cable does not run too close to the network cable
– whether the sensor is connected to the terminal
– if the sensor is not damaged – check it

Set the parameter Extending HUW pump operation time = 0

Turn the boiler off in the OFF mode, then enter the CONNECTIONS TEST and start the feeder until fuel appears in the burner. (MENU – CONNECTION TEST – Tray – ON)

Turn the boiler off in the OFF mode, then enter the CONNECTIONS TEST and start individual pumps.
MENU – CONNECTIONS TEST – CH pump – On
HUW pump – On
Pump P3 – On
Circulation – On

In order to discharge water quickly, the controller will start all the pumps and open the mixing valve to the maximum, in the case of higher temperatures, the STB protection will be activated, which will mechanically disconnect the fan / feeder.

– the STB protection has been activated (wait for the boiler temperature to drop and press the white safety button)
– the power plug has been disconnected from the socket
– if the feeder is equipped with a reverse, the switch position is set to 0
– the starting capacitor of the feeder / fan has been damaged (replacement required)

6.3 A glass fuse.

The mixer sensor should be placed behind the mixing valve, behind the pump.

There are operating modes in the SILVER controller:
S – firing up
N – normal operation
P – sustain
D – afterburning / blanking

There are operating modes in the GOLD controller:
Lighting
work
Holding
Afterburning
Putting out

The boiler hysteresis should be set in the range 1-5.

In order for the boiler to work on the basis of the weather, it is necessary to:
– in the boiler MENU, select the operating mode: Weather (menu-> boiler-> weather mode)
– in the CO / CO1 / CO2 menu, set the heating curve in accordance with our preferences (menu-> co-> heating curve)

The controller supports every traditional two-wire room thermostat, make-break.

In the SILVER controller:
For FL310: NC and COM
For FL310A and FL310 (present in the SMART boiler): NO and COM
In the GOLD controller: NO and COM

If there is a mixing valve with an actuator in the hydraulic system, the room thermostat, when it detects that the preset temperature in the room has been reached, will lower the central heating circuit temperature by the value selected in MENU → CH → Reducing the room regulator.
In the absence of a valve with an actuator, the room thermostat will switch off the central heating pump when it detects that the set temperature has been reached. In such a case, in MENU → Co → Mixer actuator must be selected as NO.

It is recommended to keep at least a 15-degree difference between the preset boiler temperature and the central heating and hot water temperature.

In the case of the eco-pea coal program, the controller performs the support function. In the case of the pellet program, the support is skipped.

The eco-pea program is selected. This function is only for pellets, it does not work with eco-pea coal.

SILVER driver:
The parameter determining the amount of fuel supplied in the combustion process is the parameter feeding 100%
Menu → Burner
In the case of feeding too little fuel, this time should be extended.

GOLD controller:
The parameter determining the amount of fuel supplied in the combustion process is the parameter feeding in the cycle
Menu → Burner
In case of feeding too little fuel, the percentage of feeding in the cycle should be increased

It determines how much time the feeder feeds fuel in the parameter: feeder cycle.
Example:
– feeder cycle 20.0 s
– feeding in a 20% cycle
– actual feeding = 20 * 0.2 = 4 seconds of feeder operation

– clean the ventilation channel under the burner crown
– if there is no improvement, increase the airflow power (menu-> dm settings in all powers should be increased by 2%)

Answer:

If we find unburnt pellets in the ash pan, reduce the airflow power / fuel supply.
To do this, we follow the steps:
– MENU-  burner feeding 100% – reduce by 0.2s
– MENU – settings reduce in all powers by 2%

The boiler controller decides that the firing-up attempt has been successful if the flue gas sensor detects a temperature 5 degrees higher than the boiler temperature. If, despite firing up the furnace, the boiler still tries to fire up, it is necessary to:
– check if the flue gas sensor is in the flue
– check the fumes sensor for contamination, in case of contamination, the sensor should be mechanically removed
– clean the boiler
– if the boiler is equipped with draft swirlers, remove one of them

– knocking on the water grates in charging boilers means that the boiler is not properly leveled
– local boiling of water on grates
– no water circulation

Explanation:

– level the boiler
– check the water circuit
– check whether the pump is working

Keep the ON / OFF button pressed for 3 seconds.

Turn off the boiler to the OFF mode, then enter the CONNECTIONS TEST and check the valve opening and closing direction, wrong connection will result in no rotation.
MENU – CONNECTION TEST – Mixer On – He
Mixer Off – On

The alarm temperature of the boiler is 90 ° C.

The STB sensor is located under the black cap on the right side of the display.

If, after setting the switch to position I, the switch starts to light, check the fuse and the fuse socket under the switch.

The CO sensor should be placed after the CO pump.

The lambda probe is located in the boiler flue, it is connected with 4 wires in a black sheath. If it is missing, the probe socket is closed with a rubber plug.

The controller does not “see” the sensor, it is caused by:
– damage to the sensor (replacement required)
– disconnection of the cube (to check, unscrew the cover above the controller and check if the cube is connected to the controller)

Activate the advanced settings, then go to the measurements in the controller and change the minimum return temperature at the very bottom. It is not recommended to set the temperature lower than 30 ° C.

If you have a manually operated mixing valve, set the knob on a higher scale. If you have a mixer actuator:
In the SILVER controller – in the CO menu it is possible to change the target temperature
In the GOLD controller – in the CO1 / CO2 menu, change the target temperature

In the case of a boiler model with a socket outlet from the rear, the thermostat is connected to the socket. In the case of the model without terminals for connection, unscrew the service cover and connect the thermostat wires directly to the controller strip.
In the SILVER controller: The cables should be connected to the Reg.Pok and GND sockets to the controller module
In the GOLD controller: The cables should be connected to the REG.POK1 / REG.POK2 and GND sockets to the controller module.

Wrong contacts have been selected in the thermostat. In this case, replace NO → NC / NC → NO
If the thermostat does not allow the contacts to be changed, the operating mode should be changed from heating to cooling. See also room controller manual)

In most cases, the DHW temperature is 45 and the hysteresis is 5. These values can be freely modified by the user.

We change the settings:
Menu → Burner → Fuel → Grate
And then we start the boiler in automatic mode. It is forbidden to open the ash pan door in order to create a draft. The air for the combustion process is supplied by a fan.

The pellet program is selected. This function is only for eco-pest, it does not work with pellets.

The feeder cycle applies to the GOLD controller. The feeder cycle determines the feeder operation time and its standstill time.

This is due to poor fuel quality.

SILVER driver:
For eco-pea coal:
Ignition – 0 min
Blower + igniter 6 min
Fire test 4 min
For pellets:
Ignition – 0 min
Blower + igniter 4min
Fire test 2 min

GOLD controller:
For eco-pea coal:
Ignition – 6 min
Fire test – 4 min
For pellets:
Ignition – 4 min
Fire test – 2 min

Initial pass should be 25 seconds.

It is possible to burn in boilers with a gutter feeder with different fuels thanks to three modes of operation.

Explanation:

The first – eco peas
The second – pellets, in this program you can burn pellets, grains, pits, fine wood chips and everything that is small granulation.
Third – grate, in this program we use wood and coal.
Of course, if we smoke with eco-pea coal or pellets, we can also burn on the upper grate, adding some wood or coal.
