I.D.: TRADP -1102 –TPX includes 2 relays:

• 1 Relay DPDT: Coil .02A, 120Vac. Pts 24Vac- 5A
• 1 Relay SPDT: Coil .02A, 24Vac. Pts 120Vac-10A
• 1- Split Duplex Receptacle, LIVE/CONTROLED
• 1- 24 hr. Interval Timer

Requirements

• Adaptor line voltage leads are connected only to the live side of the receptacle
• Line voltage leads shall be suitably cabled, fastened and en­closed in suitable raceways

Instructions

• Turn thermostat to lowest setting
• Turn off electrical power to furnace
• Turn off 120Vac power leading to Adaptor
• Select suitable location for the Adaptor
• Select a suitable location for inlet Damper & connect to Adaptor terminals 3 & 1 for Power Open Damper –or- 3 & 2 for Power Close type
• Check capacity of 24VAC Transformer

Note: If Inlet Damper is also required to Open during furnace firing:

• Option #1 Use damper that is Power Close with relay and follow its instructions.
• Option #2 If a Combustion Air Damper is included, use an Inlet Damper that is Power Close (without a relay) and connect to terminal 4 of the Combustion Air Damper and terminal 2 of Adaptor.

• Connect Adaptor Terminal 5 to Furnace R, Adaptor terminal 3 to Furnace C (or ground) and Adaptor terminal 6 (GF) to Furnace G
• Note: For thermostats having a ‘G’ terminal, connect Thermostat ‘G’ to Adaptor Terminal 7 (GT)
• Connect LINE voltage wires to the LIVE HALF of the Receptacle only as per wiring diagram.
• Turn on 120VAC power supply to the Adaptor and 120VAC power supply to furnace
• TIME­R: Set cycles as per instructions with it
• Turn interval timer clockwise through one full turn (24 hrs) to test chosen settings

Exhaust Fan, Furnace Circulation Fan and Damper will respond simultaneously for each setting, set timer for time of day.

• If a designated ventilation Switch is used, or Manual Override Switch is used, connect in series to the two live Receptacle Terminals (Red & Black).
