10 Troubleshooting
Let only trained specialist personnel carry out adjustments and troubleshooting! Standard settings for the
controller are made by customer service during commissioning. The operator and contracting partner is
responsible for additional corrections and program adjustments!
Fault/display Cause Solution
Heating system does
not heat up,
no fault 1. PSU shutdown
2. Energy transfer to the
heating circuits is
interrupted or too low
3. Power failure
4. DHW priority
Chick individual room controls, vent
heating circuit,
open valves,
check DHW circulation pump, increase
output level of the DHW circulation pump
Check fuses
Heat pump only
produces DHW but does
not heat or heats too
late DHW target temperature is too
high Check the DHW target temperature
Anti-legionella mode Use time program
Install electric immersion heater for DHW
DHW circulation hydraulics Reduce flow rate and use timer
DHW heat exchanger scaled up Notify heating contractor, clean heat
exchanger, descale
DHW temperature not
reached or no longer
reached Heat exchanger for DHW is too
small Increase size of heat exchanger
Heat exchanger is scaled up Descale heat exchanger
Sensor positioned incorrectly Position correctly
Pipework too small Install larger pipes
Faulty DHW sensor replace
DHW charging pump faulty replace
DHW charging pump output
level set too low Set higher output levels
3-way switching valve faulty replace
Heat pump runs
continually and yields
only low temperature;
traces of oil in the
appliance Escaping refrigerant
refrigerant line leaking Switch off heat pump,
notify customer service
Er.91
insufficient flow rate The minimum flow rate at the
heat pump is not being reached. insufficient system pressure,
Check pressure maintaining device, buffer
charging pump faulty,
diverter valve faulty
No hot water and
heating system remains
cold. Power failure Check cause!
Reset circuit breaker.
