Only possible with the humidity-temp. sensor KWL-FTF accessory.
Connect the analogue output A2 (temp. signal) of the KWL-FTF to the analogue input AI2 of the ventilation unit (see
wiring diagram).
If the outside temperature is below the adjustable limit (winter), the outdoor compensated supply air temperature cont-
rol will be activated (see b. Outdoor Compensated Supply Air Control). Otherwise (summer), the cascade room tempe-
rature control will be activated (see c. Cascade Room Temperature Control).

The room temperature can be adapted when the outside temperature rises. For example, a slightly higher room tem-
perature may be acceptable at higher outside temperatures, or a slightly lower room temperature in cooler weather
