Temperature control by means of an external temperature probe (not recommended for ZXDE
units)

The temperature of a cold room or cooling cabinet can be controlled by means of an additional
temperature (Analog Input AI7, component B7 in w

iring diagram) probe (NTC, 10kΩ - for detailed

temperature-resistance-curve, see

Appendix 8

). The probe can be located in the evaporator or in

the room. The location of the probe has to be considered for the configuration of the

P7C/A19

setting.

Based on the value provided by the

-temperature sensor the compressor will be switched on and

off according to the following graphics:

Figure 9: External temperature sensor

The following parameters need to be changed to control a cooling cabinet or a cold room with a
temperature sensor:
