characteristic changes and an alarm message occurs. Replace the sensor
if the connection and resistance characteristics are OK.
If you activate the mixing valve, make sure the valve sensor is connected.
Otherwise, an alarm message will occur. Be careful when extending the
sensor cable. The standard resistance at room temperature is 2 kΩ. If you
extend the sensor too much, the resistance characteristic changes and an
alarm message occurs. Replace the sensor if the connection and
resistance characteristics are OK.
The maximum ignition phase time is 30 minutes. If the flue gas
temperature does not exceed 80°C or the CH temperature does not
exceed 40°C by that time, an alarm message will occur.
If the boiler is connected to the Internet via opop.emodul.eu, it may
happen that the connection to the router is not detected during
registration. In this case, make sure that the Internet cable connection is
OK, that you are registering according to the instructions. If problems
persist, ask your ISP to unlock the communication port 2000 on your
router or call the OPOP service.
If the boiler is in operation for more than 30 minutes and the CH
temperature has not exceeded the minimum limit by that time, an alarm
message will occur. Make sure that the boiler is filled with water, that the
CH sensor is properly positioned in the water inlet on the back of the
boiler. Alternatively, call the OPOP service.
If you activate an additional pump, one of this pump's functions is floor
heating. Before activating the additional pump, first connect the sensor.
The sensor is a KTY type. Be careful when extending the sensor cable. The
standard resistance at room temperature is 2 kΩ. If you extend the sensor
too much, the resistance characteristic changes and an alarm message
occurs. Replace the sensor if the connection and resistance characteristics
are OK.
If the room thermostat is activated but is not connected, this error state
will be announced. Make sure that the thermostat is properly connected,
functional and connected to the power supply.
If a higher current consumption is generated on the fan, this alarm
message may occur. Check the fan's cleanliness and proper fan propeller
attachment. The propeller must not be deformed in any way. Check the
area of the spiral cabinet behind the exhaust fan, which must be clean and
without ash deposition. Also check the operation of the fan, no grind can
be heard. If the problems persist, call the OPOP service.
If any of these accessories are activated but not physically connected, an
alarm message will occur. Check for correct connection and accessory
settings. Alternatively, call the OPOP service.
In the event of a flue gas temperature drop, information regarding the
empty filling shaft is displayed. This happens when the flue gas
temperature drops below 48°C in the Operation mode. At this time, it's
possible to add new fuel to the hot layer. If the temperature drops even
more, below 35°C, Extinction will be announced and the boiler (fan)
switches off.
If the temperature on the mixing valve is higher than 85°C, an alarm
message will occur. Ensure that the boiler is properly connected to ensure
that its output corresponds to the heat loss of the building. In accordance
with the law, the boiler must be operated with a buffer tank to store
excess heat.
The maximum CH temperature is controlled by two sensors, namely the
CH sensor (KTY type) and the STB sensor (safety sensor). Both sensors are
located at the back of the boiler. If the CH temperature exceeds 85°C, the
CH sensor will sound an alarm. If the CH temperature continues to rise,
the fan power is deactivated by means of the STB safety sensor at a
temperature above 90°C. In this case, after cooling the boiler, it is
