SENSOR 1. CIRCUIT
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.
E16
CORRECTOR
1. CIRCUIT
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.
E17
SENSOR 2. CIRCUIT
Possible cause:
Termination in cables between the 2nd
heating circuit and control sensor, control contacts, cold
connection or defective sensor.
Boiler status:
The boiler operate normally, 2 circuit stop to
operate,switch off 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.
E18
CORRECTOR
2. CIRCUIT
Possible cause:
Termination in the cables between the 2
heating circuit connector and control unit. Control unit
contacts, cold connection or defective corrector.
Boiler status:
The boiler operate normally, the 2nd heating
circuit continues to operate as if the converter is off.
Troubleshooting:
Call a qualified service person to check the
location of the corrector, check for damage / correctness and
cable , check the connection of the the connectors.
E19
PHOTOCELL ERROR
Possible cause:
Interruption in cables between the photocell
and control, control contacts, cold or faulty photocell.
Boiler status:
Departure in phase of shutdown S7 (S7-1).
Troubleshooting:
Contact an authorized service person to
check the damage / correctness of the photocell and the cable ,
check the connections on the connectors.
E20
SAFETY THERMOSTAT
OR DOOR
MICROSWITCH
Possible cause:
Too high boiler water temperature (above 101
°C) or open lower boiler door, poorly positioned microswitch at
the bottom boiler door (not pressed enough when the door is
closed), defective microswitch with lower boiler door.
Boiler status:
The pellet transporter and the burner fan
momentarily stop operating, ie the boiler is currently in the OFF
phase. The fan and the transporter lose power and do not even
run the manual test.
Troubleshooting:
If the lower boiler doors are open they should
be closed, if they are closed, check the position of the
microswitch (if it is pressed sufficiently) and its correctness. If
everything is checked with the microswitch and the fault is still
active, check that it has released the safety thermostat. Wait for
the water temp
.
in the boiler to be below 70 °C and perform the
procedure from "SAFETY
THERMOSTAT_Case of boiler
operation".
