Free cooling is enabled, when:
1. room humidity is within determined limits (see diagram).
2. outside air temperature is within defined limits.
- upper limit: EcoCool start temperature

respectively:
Ecocool start temperature ➊ + Eco hysteresis ➋ .
- lower limit: anti-freeze temperature
➎
respectively: anti-freeze temp. ➎ + fix hysteresis of 1K.
Above the upper outside air temperature limit the enabling is pos-
sible as soon as the outside air temperature is lower than the room
temperature by an adjustable temperature difference
