"Putting a Damper on Cold Air"

Installation Instructions for HMI HOYME RADP-1102-TPX

A Dual Voltage Control Center that INTERLOCKS a 24 Vac Motorized Air Inlet Damper with End Switch to a 120 Vac Plug-in Exhaust Fan and Furnace Circulation Fan.

  

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

 

RADP - 1102 - TPX

 

      

 

  4” x 5” x 2 ½”

 101 x 127 x 64 mm 

This Adaptor (RADP-1102-TPX) acts as an automatic con­trol cen­tre to: 1) open a 24Vac motorized air  Inlet Dampe­r with an End Switch  that proves to be open (interlocked) before 2) starting a plug-in type Exhaust Fan and 3) simultaneously turning on a furnace circulation fan. It has two Relays and a split Duplex Receptacle, one side live and the other side controlled. If using a Damper without an End Switch, a jumper wire is required between Adaptor terminals #1 and #4. All items will then turn on simultaneously. The Adaptor is controlled with a Ventilation Switch and/or a Timer.

 

Fitness of this Adaptor/Damper combination to

satisfy air supply requirements for fuel fired

appliances during operation of the inter-

co­nnected 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.: RADP -1102 –TPX c/w 2 relays: Coil -120Vac and Coil - 24Vac; Contacts 10 Amps; Split Dual Receptacle

 

- 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.

- Refer to local and applicable codes.

- Always conduct a thorough checkout after installation is complete.

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

 

NOTE: THE FOLLOWING HOOK-UP PROCEDURES ARE SUGGESTIONS AND DO NOT LIMIT THE USES OF THIS ADAPTOR.

 

1. Turn thermostat to lowest setting.

2. Turn off electrical power to furnace.

3. Turn off electrical power leading to Adaptor.

4. Select suitable location for the Adaptor. 

5. Select a suitable location for Inlet Damper.  Connect Damper #3 to Adaptor #3 and Damper #5 to Adaptor #1 for Power Open Damper or #2 for Power Close Damper.

6. To interlock Damper to prove to be open before exhaust fan starts, connect end switch of the Damper to Adaptor terminals #1 and #4.  Check capacity of 24Vac transformer.

 

Option: If Inlet Damper is also required to open during furnace firing: 1) Use damper with end switch that is Power Close c/w relay and follow its instructions. Alternate: 2) If Combustion Air Damper is also used, a Power Close Damper with end switch and without  a relay is connected to inlet damper terminal #3 and to combustion air damper terminal #4. 

7. Connect Adaptor terminal #5 to furnace R,  

 Adaptor terminal #3 to furnace C (or ground)

 and Adaptor terminal (GF) to furnace G. (G

 may vary for each type of furnace). NOTE: For

 Heat/Cool thermostats, connect Thermostat ‘G’ to Adaptor terminal GT.
