SENSOR
1. CIRCUIT
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.
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.
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.
Possible cause: Termination in cables between the 1st
heating circuit and control sensor, control contact, cold
connection or defective sensor.
Boiler status: The boiler operate normally, the 1st circuit stops
to operate, shutdown the pump.
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.
Possible cause: Termination in cables between the 1st
heating circuit regulator and control, control contact, cold
connection or defective corrector.
Boiler status: The boiler operate normally, the 1st heating
circuit continues to perate as if the corrector is off.
Troubleshooting: Call a qualified service person to check the
location of the corrector, check for damage/correctness of the
correctors and cable, check the connectors on the connectors.
