Damaged equithermal sensor
Damaged outdoor sensor built-in valve
Damaged return sensor
Damaged valve sensor
Failed ignition
Module not found

Temperature does not increase
Too high floor temperature
INFO
It can not automatically ignite because the transition between igniting
and operation is based on the flue gas temperature. You can ignite the
boiler manually in Manual mode. Check for an adequate connection of
the flue gas sensor, or, if the connection is OK, replace the sensor.
The buffer tank sensor is a KTY type. Check the buffer tank sensor
connection. Be careful to extend the cable of this sensor. The standard
resistance at room temperature is 2Kohms. If you extend the sensor too
much, the resistance characteristic and the alarm message change. If the
resistor is well connected, replace the sensor.
The boiler output sensor is KTY type. Check its connection. If the wiring is
correct, replace the sensor with a new one.
The DHW sensor is KTY type. Check the DHW sensor connection. Be
careful to extend the cable of this sensor. The standard resistance at room
temperature is 2Kohms. If you extend the sensor too much, the resistance
characteristic and the alarm message change. If the resistor is well
connected, replace the sensor.
The MOSFET transistor is the component responsible for changing the
speed of the exhaust fan. The standard temperature on this component
does not exceed 50 °C. If the temperature is too high, there will be an
alarm message. Check the operation of the exhaust fan, remove it, clean
it and try again. If the problem persists, call the OPOP service.
If you connect an outdoor temperature sensor, it is possible to control the
mixing valve equithermally. So adjust the set temperature on the valve
according to the outside temperature. Before activating this function,
make sure that the outdoor sensor is properly connected. Otherwise, an
alarm message will occur. Too long sensor cable can cause change of
resistance characteristic and alarm message.
The return sensor is KTY type. Check the return sensor connection. Be
careful to extend the cable of this sensor. The standard resistance at room
temperature is 2Kohms. If you extend the sensor too much, the resistance
characteristic and the alarm message change. If the resistor is well
connected, replace the sensor.
If you activate the mixing valve, make sure the valve sensor is connected.
Otherwise, an alarm message will occur. Be careful to extend the cable of
this sensor. The standard resistance at room temperature is 2Kohms. If
you extend the sensor too much, the resistance characteristic and the
alarm message change. If the resistor is well connected, replace the
sensor.
The maximum ignition phase time is 30 minutes. If the flue gas
temperature does not exceed 80 °C or the temperature of the CH does
not exceed 40 ° C, an alarm message will occur.
If the boiler is connected to the Internet via opop.emodul.eu, it may
happen that the link 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 instruction manual. If problems persist, ask
your ISP to unlock the communication port 2000 on your router, or call
OPOP service.
If the boiler is in operation for more than 30 minutes and the temperature
of the boiler has not exceeded the minimum limit for that time, an alarm
message will be issued. Make sure that the boiler is filled with water, that
the CH sensor is properly positioned in the water sink on the back of the
boiler. Alternatively, call the OPOP service.
If you activate an additional pump, one of the functions of this pump is
floor heating. Before activating the additional pump, first connect the
sensor. The sensor is KTY type. Be careful to extend the cable of this
sensor. The standard resistance at room temperature is 2Kohms. If you
