Humidistatic switch-off:
To prevent excessive humidity build-up in the room, a humidistat
can be connected to a variable input.
Cooling without humidistatic switch-off:
Cooling with humidistatic switch-off:
If the set humidity is exceeded, a short-circuit results. A triggered
humidistat interrupts cooling mode.
Active cooling does not affect the heat generator. Demand from
other heating circuits for the heating generator or hot-water
loading is served in parallel.
