• Free cooling in winter:
In some cases, it may be necessary to cool a room even in the heating season when, for example, a place is very crowded
and the temperature rises too high.
Operation with modulating damper:
Do following settings:
-
170
=1 or 3 (authorization of free cooling regardless the season),
- do the regulation on room sensor (internal or remote sensor)
001
=0;
in case the remote sensor is used set an analogue input as remote sensor
019
=1 (AI1) or
021
=1 (AI2) or
023
=1 (AI3)),
- set an analogue input as external sensor
019
=3 (AI1) or
021
=3 (AI2) or
023
=3 (AI3),
- external modulating damper regulated on free c/h:
010
=3,
011
=1 or 2 and
030
=9 (AO1) or
031
=9 (AO2) or
032
=9 (AO3),
or modulating bypass for heat exchanger
010
=4,
011
=1 and
012
=1,
030
=13 (AO1) or
031
=13 (AO2) or
032
=13 (AO3).

: hysteresis for control of free heating/cooling
If the control temperature rises above WHS +
123,
the modulating damper in the presence of free cooling goes from the
minimum opening position (parameter
164
) to the maximum opening position (parameter
165
) in the band defined by the
parameter
178
.
Note: if external modulating damper is used, the presence of the heating battery is mandatory:

If modulating bypass damper for heat exchanger is used, the presence of the heating battery is not mandatory.
Operation with on/off damper:
Do following settings:
