The Humidity Sensor connected in the Terminal 17-18. The controller receives the relative humidity signal in the
form of voltage signals (DC0~10 V).
The respective room humidity is calculated via the linear characteristic which is defined by 2 fixed points (voltage
value1 / function value1 and voltage value2 / function value2).
Note: Alarm control logic
PCB(Controller) displays error code L5 (Sensor Humidity failure), when the detected voltage of Humidity
sensor (Terminal 17-18) is below DC0.15V or above DC9.8V.
Considering 2% of deviation for PCB circuit, the alarm may be displayed if the humidity is 96% or higher
(DC9.6V or higher).
The controller compares room humidity (detected with humidity sensor) with the humidity set point (Par 4401,
4402) and switches the external dehumidifier connected to the Terminal 45-N.
