ALARMS
6 720 806 768 (2013/02)60
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required in category A.
21.10.6 LOW TEMPERATURE COLLECTOR CIRCUIT OUT E2X.T11
Function: Warning/alarm is given if the temperature of the collector
circuit out is too low. First, a warning is given. If the warning appears
several times during a certain time period, the warning transforms into a
category A alarm.
For settings of T11: (Chapter 20.9).
Alarm timer starts: Yes.
Reset condition: T11 exceeds the lowest permitted temperature T11
plus hysteresis.
Category: J which goes over into A.
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required in category A.
21.10.7 TOO HIGH BOOT COUNT I/O BOARD BAS X
Function: Compressor stops. Is activated if the controller has executed
more than three new starts after the alarm Check CANbus cable
connection,
( Chapter 21.10.40).
Alarm timer starts: Yes.
Reset condition: The CAN-BUS communication with the controller has
been restored.
Category: A.
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required.
▶ Contact the installer if the alarm remains after acknowledgement.
21.10.8 MOTOR CUT-OUT 1 E2X.F11, COMPRESSOR
Function: Activated when the compressor's motor cut-out has tripped
because of high current or lost current phase resulting in undue strain on
the compressor.
Alarms may also be due to alarms from the soft starter ( Chapter
21.1).
Alarm timer starts: Yes.
Reset condition: Motor cut-out reset.
Category: B.
Alarm lamp/buzzer: Yes.
Restart: Reset the motor cut-out / correct the softstarter alarm.
21.10.9 FAILURE ON SENSOR E2X.T6 HOT GAS
Function: The compressor stops because the hot gas cut-out cannot be
guaranteed. Activated when the sensor's value indicates a temperature
lower than -50 °C.
Alarm timer starts: Yes.
Reset condition: The value of the sensor indicates >
-50 °C.
Category: E.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.10 SHORT CIRCUIT ON SENSOR E2X.T6 HOT GAS
Function: The compressor stops because the hot gas cut-out cannot be
guaranteed. Activated when the sensor's resistance value indicates a
temperature higher than 150 °C.
Alarm timer starts: Yes.
Reset condition: The value of the sensor indicates < 150 °C.
Category: E.
Alarm lamp/buzzer: Yes.
Restart: Automatic once the alarm cause has disappeared.
21.10.11 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.
21.10.12 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.
21.10.13 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.
21.10.14 FAULTY PROTECTIVE ANODE E41.F31
Function: The alarm is activated when the anode in the hot water
cylinder is broken or does not work. This alarm occurs only when
Protective anode installed is set to Yes.
Reset condition: The anode should be replaced so as to prevent
corrosion in the hot water heater.
Category: H.
Alarm lamp/buzzer: Yes.
Restart: Acknowledgement is required.
21.10.15 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.
