•
inputs:
1.
Boiler output water temperature measurement (NTC sensor),
2.
Flue gas temperature sensor in chimney (PT1000 sensor),
3.
HUW boiler water /return water temperature measurement (NTC sensor),
4.
Door sensor – reed relay,
It also contains four outputs allowing direct connection of 230 V AC devices, i.e.: fan, CH circulation pump,
