I need to control two relays over a single pair of wires with one wire referenced to ground.
Voltage 24VDC available at the Relays location.
One relay will control temp up, the other temp down.
One switch will activate temp up and the other temp down on a thermostat. The two switches are connected to same pair of wires and need to activate its respective relay.
Any ideas would be appreciated.
