Installation Instructions for HMI HOYME Adaptor 1102-TW5

24/120Vac Controlled Line Voltage to Switch 24Vac

Installation Of This Adaptor Shall Be In Accordance With The Requirements Of the Authorities Having Jurisdiction.

Refer also to HOYME Installation Instructions: Combustion Inlet Air Control Damper, Series HOM; Replacement/Ventilation Air Control Damper - HAC-0x10-OPC/PO; ADP-1101-05 and ADP-1102-TWP.

ADP-1102-TW5

ADP-1102-TWP - Interface Relay Adaptor

4” x   5”  x 2 1/2” (101 x 127 x 64 mm)

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.

If the damper is to also open during furnace firing, go to Installation Instructions for ADP-1103-TW5. These installations will not affect the operation of the furnace or Air Conditioner. 

Fitness of this Adaptor/Damper combination to satisfy air supply requirements for fuel fired appliances during operation of the in­terconnected exhaust fan(s) shall be investigated by the enforcing authorities.

 Air intake duct installation shall be in accordance with: In Canada - CAN/CSA B149 & B139; In the USA – ANSI/NFPA 54, 2006, ANSI Z223.1 and/or local codes including local codes relating to ventilation air duct installation.

I.D.: ADP -1102 - TW5
One Relay DPDT: Relay Coil -120 Vac
One Relay DPDT: Relay Coil - 24 Vac
All Contact 
Points are 24Vac - 5 Amps

Adaptor line voltage leads, connected to the 120Vac exhaust fan controlled line, shall be suitably cabled, fastened and enclosed in suitable raceways.

- Always refer to local and applicable codes.

Always conduct a thorough check-out after installation is complete.

Affix appropriate labels and follow instructions and warnings on each label.

Connecting the Adaptor ADP-1102-TW5 to a controlled 120Vac Designated Ventilation Exhaust Fan and heating appliance.

1. Turn off electrical power supply to exhaust fan circuits and to the furnace.

2. Connect the controlled 120Vac exhaust fan circuit to the Black and White adaptor leads as per wiring dia­gram. Follow applicable codes.

3.  Connect Adaptor terminal #5 to the furnace terminal ‘R’ (24 Vac).

4. (a) Disconnect the thermostat wire ‘G’ (if used) from the furnace terminal ‘G’  and connect it to the Adaptor terminal #3(GT).

    (b) Connect Adaptor terminal #4(GF) to the furnace ‘G’.

5. Turn on the power supply to both the furnace and to the exhaust fan. Turn on the exhaust fan which will simultaneously turn on the furnace circulation fan.

Connecting an exhaust fan with (a) controlled 2C-24Vac signal or (b) using dry contacts, to connect to the Adaptor 1102-TW5.

6. Turn off the power supply to both the furnace and the exhaust fan.

7. (a) Connect the controlled 2C-24Vac signal from the exhaust fan to Adaptor #6 & #7.

 (b) If using dry contacts, connect one wire to Adaptor terminals #7 and the other wire to furnace terminal ‘C’, and add a jumper wire between Adaptor Terminals #5 & #6.

8. Turn on the power supply to both furnace and exhaust fan. Turn on the exhaust fan switch which will simultaneously cause the furnace circulation fan to run.

Connecting a replacement fresh air damper (if used) to open simultaneously with either exhaust fan running.

9. Turn off the power supply to the furnace.

10. Install a Hoyme ‘HAC’ 2C-24Vac motorized fresh air control damper to the duct as per instructions supplied with it. Satisfactory opera­tion of the damper is recommended before fastening to the fresh air duct.

(a) For a Power Open damper, connect one damper wire to Adaptor terminal #1 and connect the other damper wire to the furnace terminal ‘C’

(b) For a Power Close Damper, connect one damper wire to Adaptor terminal #2 and connect the other damper wire to furnace terminal ‘C’.

11. Turn on the power supply to the furnace. If the damper is a Power Open type, it will remain closed at this time. If damper is a Power Close type, it will close at this time.

12. Turn on either exhaust fan. The exhaust fan(s), the furnace circulating fan and inlet damper will operate simultaneously.
