:
hysteresis regulation free heating/cooling
P: rotary on/off heat exchanger output
Bypass: on/off bypass damper output
With cooling recovery conditions:
If temperature of regulation sensor rises above WCS, icon
is switched on, the rotary on/off heat exchanger is activated and
the on/off bypass is deactivated. The rotary on/off heat exchanger is deactivated and the bypass damper activated if Treg <=
(WCS -
178
). The icon is switched off.
Operation with modulating bypass heat exchanger and modulating heating valve:
Do following settings:
- set type of heat exchanger
012
=3
,
- select a digital output for the rotary on/off heat exchanger
025
=14 (DO1) or
026
=14 (DO2) or
027
=14 (DO3) or
028
=14 (DO4)
or
029
=14 (DO5)
- do the regulation on room sensor (internal or remote sensor)
001
=0;
- define the return air sensor
019
=1 (AI1) or
021
=1 (AI2) or
023
=1 (AI3)
-
define external sensor
019
=3 (AI1) or
021
=3 (AI2) or
023
=3 (AI3).
If return sensor or external sensor is broken (open or short-circuit), heat exchanger is deactivated.
