TROUBLESHOOTING - FW 100
Remedy
Power up all ISMs simultaneously and
start automatic system configuration.
Check HLC.
Check solar parameter T2.
Is thermal disinfection active?
Check connection.
Check system configuration for
domestic hot water system or start
automatic system configuration.
Check system configuration for heating
circuit
Check outside temperature sensor and
remedy interruption, if necessary.
Check system layout, check system
configuration, modify if necessary and
set parameter again.
In combination with FW 100 only
coding 1 is possible in the remote
control.
Check system layout, check system
configuration, modify if necessary and
reset parameters on remote control.
Check mixer temperature sensor (MF)
and replace if necessary.
Remove the temperature sensor and
insert a coding plug if necessary.
Check temperature sensor (T
replace if necessary.
