Electronic Temperature And Humidity Controller; Applications For Temperature Controller - Siemens NXAIR Operating Instructions Manual

28.3 Electronic temperature and humidity controller

The electronic temperature and humidity controller can either be designed as a normally closed contact or as
a normally open contact:
Temperature function
Humidity function

28.4 Applications for temperature controller

Mechanical temperature controller
Electronic temperature and humidity controller
110-0134.9 / 14
NOTICE
Damage due to incorrect application
The temperature and humidity controllers require direct connection to the ambient
air.
Do not cover the ventilation slots of the temperature and humidity
controllers.
If the ambient temperature falls below the adjusted value, the circuit for
heater operation is closed (LED lights up).
If the ambient temperature rises above the adjusted value, the circuit for
heater operation is open (LED does not light up).
If the relative humidity rises above the adjusted value, the circuit for heater
operation is closed (LED lights up).
If the relative humidity falls below the adjusted value, the circuit for heater
operation is open (LED does not light up).
