c) Connection
Observe chapter "Safety Information"!
• First feed the connection lines through the cable feedthroughs.
The single small cable feedthrough is meant for the cable of the temperature sensor.
• Push the cable of the temperature sensor through the enclosed shrink hose.
• Screw the two lines of the temperature sensor to the corresponding terminals (above in figures 1+2; "P2" and "GND"
on the PCB). The polarity is irrelevant for this.
In any case, ensure that the cable of the temperature sensor is pro-
tected by the shrink hose between the cable feedthrough and the two
screw terminals. This is done to produce the double insulation of the
temperature sensor cable.
Secure the shrink hose on one side in the feedthrough (tighten the
shrink hose with the temperature sensor cable in the cable feedthrough
by turning); fixate the shrink hose with a cable clip at the other end,
near the screw terminals.
• Strip the cables of the mains supply line and the connection line to the cooling/heating unit accordingly and attach
them to the corresponding screw terminals.
Terminals 3+4, "COMPR": Cooling unit
Terminals 7+8, "DEFROST/HOT": Heating unit
Terminals 5+6, "POWER": Connection to the mains voltage
The temperature controller switches the connected cooling or heating unit on depending on the temperature
measured and its programming.
Mains voltage is therefore pending at the outputs 3+4 ("COMPR") or 7+8 ("DEFROST/HOT").
The heating or cooling unit connected to the temperature controller therefore requires a mains voltage input.
Otherwise, it must not be connected to the temperature controller.
