13.3 Thermistors
13.3.1 Location of the thermistors
Different thermistors need to be installed depending on the control
type. Follow the table below for this.
Thermistor Control type
X Y W Z Z'
R1T: Suction air — — — ● ●
R2T: Liquid pipe ● ● ● ● ●
R3T: Gas pipe ● ● ● ● ●
R4T: Discharge air — — — — ●
● Required
— Not required
Correct installation of the thermistors is required to ensure good
operation.
R1T Thermistor (suction air)
Install the thermistor either in the room that needs
temperature control or in the suction area of the air
handling unit.
Note: For room temperature control the delivered
thermistor (R1T) can be replaced by an optional remote
sensor kit (see the technical engineering data).
R2T Thermistor (liquid pipe)
Install the thermistor behind the distributor on the
coldest pass of the heat exchanger (contact your heat
exchanger dealer).
R3T Thermistor (gas pipe)
Install the thermistor at the gas pipe of the heat
exchanger as close as possible to the heat exchanger.
R4T Thermistor (discharge air)
Install the thermistor in the discharge area of the air
handling unit.

Evaluation must be done to check if the air handling unit is protected
against freeze-up. This must be done during test operation.
The thermistor needs to be installed in an enclosed area. Install it
inside the air handling unit, or shield it to prevent it from getting
touched.
