Fan demand operation
The fan will only be operated in the manually selected speed, if the regulator has detected a request for Heating or
Cooling. During dead zone the fan will be OFF. Through a

If a water sensor is present (not possible on remote H/C models) ventilation will only start if the water sensor detects a
temperature above 30 degrees. If this is not the case, it waits for consent from the sensor.
If there is no sensor, ventilation will always start after the 150 seconds delay time from

6.3
Periodic ventilation
Ventilation will be started for two (2) minutes at the end of the cycle to recycle air on the room air sensor if there has
been no ventilation in the last twenty (20) minutes.
This prevents stratification of the air in the room, which will falsify the room temperature reading.

This prevents equipment inside the room from freezing.
