For WS 170 in passive-energy hou-
ses, an NTC 15 must also be instal-
led to protect against icing over (if
the supply air is too cold). The venti-
lation unit then switches off at supply
air temperatures of less than 6 °C.
Only in Comfort and Bypass units
when deploying a supply air tem-
perature sensor:
Remove the resistor on GW1 circuit
board at the KL2 terminals.
