17.9.11 High flow temperature E1x.T1
Function: The compressor stops because the flow temperature is too
high for the heating circuit. Activated when the sensor shows a value
which is 5K higher than the highest set point value for the circuit. The
factory setting for the highest set point value is 60 °C for radiator type of
circuit and 35 °C for underfloor type of circuit
After hot water production, the alarm is delayed with 4 min.
Alarm timer starts: Yes.
Reset condition: The sensor's value falls below the temperature for
beginning of the heating demand.
Category: E.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.12 Faulty electric heater E21.E2
Function: The electric heater is turned off. Activated by tripped
overheat protection on the electric additional heat, high flow
temperature or too high temperature in electric additional heat. The
automatic trip fuse to the electric additional heat may have been tripped
due to, for example, a short circuit.
Reset condition: Overheat protection reset.
Category: F.
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required.
17.9.13 Overheat protection tripped hot water electric heater
Function: The electric heater is turned off. If alarm output from the
electric heater has been connected to the multi module, the alarm is
given when an error occurs.
Reset condition: The error in the electric heater has been overcome and
no alarm signal.
Category: F.
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required.
17.9.14 Faulty protective anode E41.F31
Function: The alarm is activated when the anode in the hot water heater
is broken or does not work. Presupposes that Yes is indicated in
Protective anode installed.
Reset condition: The anode should be taken care of so as to prevent
corrosion in the hot water heater.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required.
17.9.15 Failure on sensor E11.T1 flow
Function: The alarm is activated when the sensor's value indicates a
temperature lower than 0 °C. The flow temperature T1 becomes
identical to T8. If there are several heat pumps installed, T1 = T8 for the
heat pump that does not produce hot water and has the highest value on
T8. Additional heat mixing valve shut.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.16 Short circuit on sensor E11.T1 flow
Function: The alarm is activated when the sensor's value indicates a
temperature higher than 110 °C. The flow temperature T1 becomes
identical to T8. If there are several heat pumps installed, T1 = T8 for the
heat pump that does not produce hot water and has the highest value on
T8. Additional heat mixing valve shut.
Reset condition: The value of the sensor indicates
< 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.17 Failure on sensor E12.T1, E13.T1... flow
Function: The alarm is activated when the sensor's value indicates a
temperature lower than 0 °C. The mixing valve for the circuit is closed
completely.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.18 Short circuit on sensor E12.T1, E13.T1... flow
Function: The alarm is activated when the sensor's value indicates a
temperature higher than 110 °C. The mixing valve for the circuit is
closed completely.
Reset condition: The value of the sensor indicates < 110 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.19 Failure on sensor T2 outdoor
Function: The alarm is activated when the sensor's value indicates a
temperature lower than -50 °C. In the event of a failure on T2, the
outdoor temperature is set to 0 °C.
Reset condition: The value of the sensor indicates
> -50 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.20 Short circuit on sensor T2 outdoor
Function: The alarm is activated when the sensor's value indicates a
temperature higher than +70 °C. In the event of a short circuit on T2, the
outdoor temperature is set to 0 °C.
Reset condition: The value of the sensor indicates
< 70 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
17.9.21 Failure on sensor T3 hot water
Function: The alarm is activated when the sensor's value indicates a
temperature lower than 0 °C. The hot water production is terminated.
Reset condition: The value of the sensor indicates >0 °C.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
