Diagram #6A1: Forced Air Furnace having a Replacement Air supply Duct together with two Exhaust Fans controlled by two separate Double Pole Ventilation Switches.*
- Replacement Air Control Damper Power Open (HAC-0x10-OPO)
- Two Double Pole Ventilation Switches with power supply from the same circuit supplies Controlled 120Vac to Furnace area. (3C wire required)
- An optional ON/OFF Switch
- Relay Adaptor (ADP-1101-05A) to function as a control center
OPERATION:
- Furnace fires with Thermostat signal
- Each Ventilation Switch turns on the Ventilation Fan, the Furnace Fan and opens the Ventilation Damper simultaneously. The (PO) Damper is connected to Adaptor Terminal #1
- Optional Switch connected between #1 and #2 of the Adaptor allows full control of the Replacement Air Damper to open as required
*Alternately, regular Ventilation Switches may be used which will require one ADP-1101-05A for each Exhaust Fan. Connect controlled 120Vac from each an to each Adaptor as shown in Diagram #6A. Place Adaptors side by side and connect the first Adaptor to the Furnace as shown above with the exception of #4 (GF). #4 of the first Adaptor will be connected to #3 (GT) of the following Adaptor and will follow in like manner to the last Adaptor. Terminal #4 (GF) of the last Adaptor will be connected to the ‘G’ of the Furnace. All other Terminals are to be connected #1-1; 2-2; and 5-5.
