CAUSE – Check/Solution
An installer is required for most checks and solu­
tions.
FAN/PCB PROBLEM
Check the PCB-fan connection
Check the fan operation
MAIN PCB ERROR
Check the electrical connections for the gas valve
SENSOR/CONNECTION PROBLEM
Check the sensor/PCB connection
Check the operation of the sensor
Switch the power supply off and on again and
then RESET
Switch the power supply off and on again and
then RESET
MAIN PCB ERROR
Check the electrical connections
CAUSE – Check/Solution
Check the solar temperature sensor wiring. Re­
place the sensor if necessary. In case of removal
of the solar tank, set the parameter DP150=1.
Check the solar temperature sensor wiring. Re­
place the sensor if necessary.
