FAULT
CODE CAUSE REMEDY
# 17 Summer mode with empty water container Switch heater off and allow to cool. Fill boiler
with water
# 18 Warm air temperature exceeded:
Not all warm air ducts are connected
Check whether the 4 warm air ducts are
connected
Warm air oulets blocked Check the individual outlet openings
Circulated air intake blocked Remove the circulated air intake blockage
# 21 Room temperature sensor or cable faulty Inspect the room temperature sensor cable,
replace if faulty
Check the resisitance of the room temperature
sensor.
15°C - 16.2 kOhm / 20°C - 12,6 kOhm / 25°C
- 10.0 kOhm
Replace room temperature sensor if faulty
# 24 Risk of low voltage. Battery voltage is too low
< 10.4V Charge battery
# 29 Frost Control heating element has a short circuit Disconnect heating element plug from
electronic control unit. Replace heating element
# 42 Open window above cowl (window switch) Clode window
# 43 Overvoltage > 16.4V Check battery voltage / voltage sources such
as the charger
# 44 Low voltage. Battery voltage is too low <10.0V Charge battery. If necessary replace old battery
# 45 No 230 V operating voltage Restore 230 V operating voltage
230 V fuse defective Replace 230 V fuse (see Combi operating

# 211
# 212 Gas cylinder empty Replacing a gas cylinder
Gas cylinder or quick-acting valve in the gas
supply line closed Check gas supply and open valves
Gas pressure regulation system iced up Use regulator heater (EisEx)
Butane content in the gas cylinder too high Use propane. Butane is unsuitable for heating,
particularly at temperatures lower than 10 °C.
Combustion air infeed or exhaust outlet is
sealed Inspect openings for obstructions (slush, ice,
leaves, etc.) and remove any obstructions
Gas pressure regulation system faulty Inspect / replace gas pressure regulation
system

No connection between heater and control
panel Make connection between heater and control
panel
