E. Set the Potentiometers and test
Now all the wiring is in place it is time to set the potentiometers to the values you recorded from
testing the AC sensors, do this using a multimeter set to resistance and set the pots shown below.
Note that you should disconnect 1 wire while setting the pots and manually change the state of the
relay to set the 2 values, once set reconnect the wire.
If your aircon unit is controlled by a thermostat instead of a
temperature sensor in the evaporator unit. Please remove the small
circuit with the potentiometers and wire the control wires directly
to the common © and Normally open (NO) terminals of the relay
as a resistance value is not needed.
