Operation with on/off bypass damper without heating valve:
Do following settings:
-
170
=2 or 3 (authorization of free heating regardless the working season), or
170
=5 or 6 (authorization of free heating in heat

Hysteresis regulation free heating/cooling
In the presence of free heating conditions:
If Treg < WHS the on/off damper is activated.
If Treg >= (WHS +
178
) the damper is disabled.

170
=1 or 3 (authorization of free cooling regardless the working season), or
170
