    What is the best way to wire a Taco Geo Sentry control valve to a 3 ton Heat Controller GeoLogix DXM2 to shut off flow when the compressor is not operating ? (open loop well system)

    The "A" terminal at P2 block provides 24vac when the compressor is running. Wire this to W/Y on the Taco Sentry Valve. Then to complete the circuit wire "C" at P2 block to "C" on the valve.

    It may take up to 30 seconds to open at startup but i have not had any issues setup this way.

    Some people use the thermostat call "Y1" to power the valve and then use the end switch to pass the signal to "Y1" on the DXM2 board. This wil open the valve before the compressor starts but it will not shut it off if there is a lockout.
