Contact Voltage
I need a 4 pin timer with voltage free contacts?
I need a timer switch that will turn on a swimming pool pump 240volts but it needs a second timer to switch on my boiler that has to have no voltage. so the pump can be set to start 10-15 minites before the boiler and then the boiler turned off 10-15 minites before the pump. But the boiler link must be voltage free any idea’s where i might get one?
The previous answer about the heating programmer is correct except most programmers are internally linked so you dont get to use the contacts volt free, Honeywell make one with volt free contacts (ST699B ) Make sure the pump load isnt too high for the rated contacts or use a contactor/starter for the pump with the clock just energising the contactor coil.
