4.5 Installation of the Thermistors
4.5.1 Refrigerant Thermistors
Location of the thermistor:
A correct installation of the thermistors is required to ensure a good operation:
(1) Liquid(RT4)
Install the thermistor behind the distributor on the coldest pass of the heat exchanger (contact
your heat exchanger dealer).
(2) Gas (RT2)
Install the thermistor at the outlet of the heat exchanger as close as possible to the heat
exchanger.

Installation of the thermistor cable
(1) The length of thermistor wire is 10 m.
(2) Put the thermistor cable in an individual protective tube.
(3) Apply stress release in the temperature sensor wire to prevent the temperature sensor
wire from getting loose due to stress. Stress or looseness of temperature sensor wire will
lead to poor contact and inaccuracy of temperature measuring.
Fixation of the thermistor
Notes:
①
Put the thermistor wire slightly down to avoid water accumulation on top of the thermistor.
