1361 102 White rodgers zone valves require a power OFF leg to close. tn2 wiring center 313 only has two? or will it flip the power back and forth between operating?
Would be a Sunday, thought it was straight forward til I remembered power on and off.

    Here is how we do it with the Caleffi relay boxes. It you do not have an end switch or dry contact, you may need to use a RIB relay.

    RIB relays is how I have done it. If you go with a 334 zone manager, you can just jumper the 24v power supply wire, as the zone valves are independently powered.
