Operation with on/off damper and cooling modulating valve:
Do following settings:
-
170

In the presence of free cooling conditions:
If Treg > (WCS +
116
/2) the on/off damper controlled by the free cooling is activated.
If Treg <= WCS the on/off damper controlled by the cooling is disabled.
The valve changes position from closed to open when Treg change from (WCS +
116
/2) to (WCS +
116
).
Operation with on/off bypass damper and cooling modulating valve:
Do following settings:
-
170

- do the regulation on room sensor (internal or remote sensor)

Hysteresis regulation free heating/cooling
solid curve: on/off damper output
dashed curve: modulating cooling valve output
With free cooling conditions:
If Treg > WCS the on/off bypass damper regulated on free cooling is activated.
If Treg <= (WCS -
178
) the on/off bypass damper regulated on free cooling is deactivated.
The valve changes position from closed to open when Treg change from (WCS +
116
/2) to (WCS +
116
).
