Errors
E10
INCORRECT BUFFER
TANK SENSOR UP
Possible cause:
Interruption in cables between
s
ensors and
control, control contacts, cold connection or defective sensor in
the accu tank upper part.
Boiler status:
Departure to the Shutdown phase S7 (S7-
1
)
.
Troubleshooting:
Call an authorized service person to check
the sensor location in the tank, check for sensor/cable damage,
check connections at the connectors, check the ohmic
resistance of the sensor.
E11
INCORRECT BUFFER
TANK
SENSOR DOWN
Possible cause:
Interruption in cables between sensors and
control, control contacts, cold connection or defective sensor in
the accu
.
tank lower part.
Boiler status:
Departure to the Shutdown phase S7 (S7-1).
Troubleshooting:
Call an authorized service person to check
the sensor location in the tank, check for sensor/cable damage,
check connections at the connectors, check the ohmic
resistance of the sensor.
E12
INCORRECT
CROSSOVER
TEPERATURE
SENSOR UP
Possible cause:
Interruption in cables between sensors and
control, control contacts, cold connection or defective sensor
Boiler status:
Departure to the Shutdown phase S7 (S7-1).
Troubleshooting:
Call an authorized service person to check
the location of the sensor, check for sensor / cable damage,
check connections at the connectors, check the ohmic
resistance of the sensor.
E13
INCORRECT RETURN
LINE SENSOR
Possible cause:
Interruption in cables between sensors and
control, control contacts, cold connection or defective sensor.
Boiler status:
Departure to the S7 (S7-1) phase, if the pump
P1 is in operation and there is a mixing valve (return protection)
it goes to 50% openness.
Troubleshooting:
Call an authorized service person to check
the location of the sensor, check for sensor / cable damage,
check connections at the connectors, check the ohmic
resistance of the sensor.
E14
INCORRECT
OUTSIDE
TEMPERATURE
SENSOR
Possible cause:
Interruption in the cables between the sensor
and control (CM2K), control contacts, cold connection or
defective sensor.
Boiler status:
The boiler operate normally, but all heating
circuits which are using external temperature sensor shutdown
the pump and the freeze protection condition (if it is switched
on) automatically assumes that the outside temperature meets
the freeze protection condition (unless the authorized service
person has switched off the external temperature requirement).
Troubleshooting:
Call an authorized service person to check
the location of the sensor, check for sensor / cable damage,
check connections at the connectors, check the ohmic
resistance of the sensor.
