Switch-on/switch-off temperature difference for R1/V1:
If this temperature difference between the reference sensors is exceeded and the
other conditions are also met, then the controller switches the ventilator on. When the
temperature drops to ΔT Off, then the ventilator is switched off.
Switching temperature of the ventilaor fl ap.
If this temperature at the outdoor sensor S3 is exceeded the controller switches the
ventilator fl ap at relay R2. If the temperature drops below the controller switches the
ventilator off.
Hysteresis for thermostat function at sensor 3
By setting the hysteresis value the heating of the sensor can be adjusted.If the temper-
ature of the Tsetpoint at sensor 3 is exceeded by the set hysteresis, additional heating
at relais R2 is deactivated. If the Energy saving mode is active (see 5.16) the system
heats up until hysteresis temperature is reached.
Switch-off temperature at sensor 3
If this value is exceeded at the applicable sensor 3, the controller switches the associ-
ated ventilator off. If the temperature falls below this value again and the other condi-
tions are also met, then the controller switches the ventilator
on again.

Tset Room
Switch-off temperature at sensor 2
If this value is exceeded at the room sensor S2, the controller switches the vebntialtior
off. If the temperature falls below this value again and the other conditions are also
met, then the controller switches the ventilator on again.
Danger
Danger
Temperature values that are set too high can lead to scalding or damage
to the system. Scalding protection must be provided by the customer!
Temperature values that are set too high can lead to scalding or damage
to the system. Scalding protection must be provided by the customer!
If the set temperature difference is too small, this may result in ineffective
operation, depending on the system and sensor positions.Special swit-
ching conditions apply for speed control (see 7.3. - Speed control V1“ on
page 23)
