T3 -40...+120 °C
Exhaust air temperature Analogue
NTC 10 kOm
T4 -40...+120 °C
Return heat medium temperature Analogue
NTC 10 kOm
T5 -40...+120 °C
External set point adjuster Analogue
0-10 V
10 V IN Enables fan speed control by means of a potentiometer.
This input is enabled/disabled via the Engineering Menu
(sensors). The terminal is energised with 10 V.
Main humidity sensor Analogue
0-10 V
RH Each of the sensors is enabled/disabled via the
Engineering menu. The sensors are energised with
24 V for powering external sensors. The power supply
overload protection is triggered by a short circuit or
a total current on the 24 V line in excess of 700 mA.
Once the overload protection is activated, the power is
restored only after a manual reset at the power supply
unit.

Supply fan control Analogue 0-10 V M1 (OUT 0-10) You can configure the minimum and the maximum value of the signal sent
to an active fan and the delay before switching to automatic control after
activating the unit.
Extract fan control Analogue 0-10 V M2 (OUT 0-10)
Analogue control of the reheater or
water heater valve control Analogue 0-10 V 0-10V OUT (1) The operation of this output depends on the heater type selected via the
Engineering Menu:
Electric.
The system controls an external circuit board which operates the
heater (e.g. multi-stage)
