- check parameter D (second digit must be 0)
- short circuit in flat cable: replace flat cable
- water/condensation on display
- possibly external EMC contamination
Check:
- the waterflow, ref. Par. 7.4.7.
- system for trapped air
- sensors for resistance at set temperature, see graph
in Fig. 22.
- if the boiler is full of water (min. pressure 0.8 bar)
- Flow sensor badly installed
- Pump operating in wrong direction or flow and return
connections crossed
- Fan or motor failed
- Supply and/or signal control cable – poor connecti-
ons or failed.
- Check control cable connections and for continuity
- Fan defective
- Flue draft conditions too high
Flow temperature sensor short circuit
Return temperature sensor short short circuit
Outside temperature sensor short short circuit
Flow temperature sensor not connected or open circuit
Return temperature sensor not connected or open cir-
cuit
check parameter D (first digit must be 0)
After 4 restarts during 1 heat demand
- flue gas recirculation (internal/external)
- insufficient air flow – check fan or air inlet/flue outlet
for obstruction
- incorrect combustion.
Fault-codes: 3, 6, 7, 10, 13, 14, 15,
16, 17, 41, 42, 44 and 60:
- Press the 'reset'-key
- When fault returns, check wiring for short circuits
- When faults still return, replace the control box
Shut-off codes: B@%,B@*, B@(, b#) or
b$#, see Par. 6.4.
