Zone Valve/ump Selection Switch ontrol must be in priority mode (priority switch ) to access this feature. With the zone valve/pump switch in the FF position, only the priority zone valve terminals are energized when Zone 1 calls for heat. With the zone valve/ pump switch in the position, the priority pump terminals will be energized with 120Vac when Zone 1 calls for heat. D-2 Selection Switch he D-2 utdoor eset ontrol is designed to raise or lower the temperature of the boiler supply water based upon a proportionate drop or rise in temperature at the outside sensor. he D-2 plugs into a data port on the Z- control with a ribbon cable. f the D-2 selection switch is in the position, the Z- will be able to communicate with the D-2.
