HMI Hoyme ADP – 1102 – TW5
This Adaptor ADP-1102-TW5 is an automatic relay control switch specifically designed, but not limited, to accommodate two separate Exhaust Fans in a dwelling interconnected to one furnace having a Replacement Air Duct and (if used) a replacement Air Damper. A controlled 120Vac signal from one Exhaust Fan and/or a controlled 24Vac signal (or dry contacts) from a second Exhaust Fan will simultaneously turn on the Furnace Circulation Fan and open the replacement Air Damper.
