:
heating proportional band
solid curve: modulating damper output
dashed curve: modulating heating valve output
If the control temperature drops below WHS, the modulating damper in the presence of free heating conditions goes from
the minimum opening position (parameter
164
) to the maximum opening position (parameter
165
) in the band defined by the
parameter
114
/2.
The valve changes position from closed to open when Treg change from (WHS -
114
/2) to (WHS -
114
).
Operation with modulating 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
-
ing mode only),
- do the regulation on room sensor (internal or remote sensor)
