Remote Supply Temperature/Humidity Sensor
The remote temperature and humidity screens appear if your unit is
confi gured for a remote supply T/H sensor. The screens display the supply air
temperature and humidity as measured by the sensor which is to be customer
installed in the cold aisle. Remote dewpoint is calculated by the controller
based on the remote supply T/H sensor inputs and shown at the bottom of the
display screen. Values measured by the sensor may be used to control the
temperature and humidity.
