In the single evaporator versions, the panel is supplied together a with kit
of three probes, P/N NTC060HP00: these must be installed to monitor the
air inlet temperature, the evaporator coil air outlet temperature and the
defrost temperature. In the multi-evaporator versions, in addition to the
three probes mentioned above, there is also one probe P/N NTC060HF01
for the compressor suction temperature.
It should be noted that the panel has four digital inputs:
• Input #1: intended for a possible door switch
• Inputs #2 to #4: free to be configured by the user.
