WR 600 ventilation unit with RSL 2 F room air control and HY 5 hygrostat
Connection of a hygrostat for demand-driven humidity extraction. This must have a potential-free switching output,
e.g. Maico Hygrostat HY 5.
The hygrostat always switches the ventilation unit to ventilation level 3 if the defined humidity value is exceeded. If the
humidity in the room drops, the ventilation unit switches back to the previously selected ventilation level.
If you switch manually or using the timer from ventilation level 3 to level 2 or 1, this deactivates the automatic function
of the hygrostat temporarily. This is then switched back to active if the level drops below the hygrostat set point once.
