PF1202T wiring

PF1222TB wiring
How to wire PF1202T and PF1222TB

Your incoming 240 volt connects to terminals 1 and 3 on FILTER timer....
Clock motors for both timers MUST connect to live 240 volt. This means clock motor on CLEANER timer must connect to terminals 1 and 3 on FILTER timer, or to a team block where 240 volt arrives inside the control center. This wiring ensures that both clock motors are running at all times, and both yellow dials are rotating once per day.

On a control center WITHOUT freeze override, terminals 1 and 3 on CLEANER timer connect to terminals 2 and 4 on FILTER timer .... this means CLEANER timer is only ON when FILTER timer is ON...

On a control center WITH freeze override, terminals 1 and 3 on CLEANER timer connect to the freeze control as illustrated, and then connected to terminals 2 and 4 on FILTER timer .... this means CLEANER timer is only ON when FILTER timer is ON, same as control center without freeze.

The freeze override will send power to the Cleaner timer when temperatures drop below thermostat set point
