Hi All
Trying to build a circuit to control dual zone fridge which uses a 12v 300mA 0.5sec pulse reverse polarity solenoid to direct gas flow.
I need one thermostat 1 ( continuous Output ) to deliver a pulse of + polarity and remain so until it goes open even if the other thermostat 2 closes, and when thermostat 1 opens to deliver a - pulse if thermostat 2 is already closed.
The other thermostat 2 to deliver a - 12v pulse and remain in that state until thermostat 2 opens and deliver a + pulse if thermostat 1 is closed.
I have the thermostats which have 10A relay switch.
