Hoyme-ADP-1102-TWP

This Adaptor is an automatic switch to open a 24Vac Replacement/Ventilation Damper during the ventilation cycle and/or during the firing cycle of the Furnace. By connecting the Adaptor 120Vac Relay Coil to the controlled line voltage of an Exhaust Fan and connecting the 24Vac Circuit to the Furnace Terminals, the Exhaust Fan, the Furnace Fan and the Inlet Damper will all operate simultaneously. The Inlet Damper may also be connected to open during the firing cycle of the furnace.
