: neutral zone
178
: hysteresis for control of free heating/cooling
If the control temperature drops below WCS -
123,
the modulating damper in the presence of free heating goes from the
minimum opening position (parameter
164
) to the maximum opening position (parameter 1
65
) in the band defined by the
parameter
178
.
Note: if external modulating damper is used, the presence of the cooling battery is mandatory:

In the presence of free heating conditions:
If Treg < (WCS -

) the on/off damper is activated.
If Treg >= (WHS -
