Other messages Instructions
flue resistance high, check heat exchanger For the necessary air differential pressure a higher fan speed than normal is required.
preventive message see documentation This could indicate that boiler, flue gas discharge line and air intake pipe and/or siphon fouling.
Controlstop Instructions
boiler diff. temp. Boiler temperature differential is getting too high.
too high Check: - boiler/installation water flow
- boiler water level
- working pressure (min. 0.8 bar)
heat exch. temp. rise Boiler temperature rise faster than usual.
too fast Check: - boiler/installation water flow
- boiler water level
flow temp. rise too fast - working pressure (min. 0.8 bar)
flue gas temp. too high Flue gas temperature threatens to rise above the set maximum value.
Check: - the set maximum flue gas temperature (see par. 7.3.3, option no. 4)
Minimum setting: 15°C above maximum return water temperature
- boiler setting
- boiler fouling
main supply voltage Mains supply too low or too high.
too low Check mains supply.
main supply voltage Take off fan cable from cable channel
too high
