This DIP Switch setting is used to match the room heating unit’s switch for room temperature set back to the configuration of the set back signaling device. This DIP Switch operates like DIP Switch #1. When the switch is in the "OFF" position, a switch contact closure in the set back signaling device will initiate the room temperature set back feature. When the switch is in the "ON" position, an open switch in the set back signaling device will initiate the room temperature set back feature.
OFF = switch closes for room temperature set back
ON = switch opens for room temperature set back
