   101 x 127 x 64 mm

 

This Adaptor, with two relays, senses a line voltage safety control signal, proves a 24Vac damper to be open and then sends the signal back to the line voltage control circuit. For DC safety control systems 250mVdc to 100Vdc,

use HMI  HOYME ADP- 0MV2-S5A.

 

I.D.: ADP- 1102 – 10A; c/w 2 Relays: Coils- 

 120Vac and 24Vac. Contacts-10Amps  

    

- For one appliance, use one Adaptor and one

 Damper, Series HOM, Type SF1.

- For two appliances, use two Adaptors and

 one damper, Series HOM, Type-SF1.

- Adaptors may be mounted on side of

  appliance control box. Leads must be

  suitably cabled and  fastened. If Adaptor is

 mounted away from control box, line voltage

 leads shall be enclosed in suitable

 raceways. Refer to local electric codes.

 

 

-Use an approved 24Vac transformer of

  adequate capacity (10 VA min.) if required.

- Supply for the transformer primary shall be

  taken from the line voltage supply for the

 appliance.  Refer to applicable codes.

- Always conduct a thorough checkout after

 installation is complete.

- Affix attached wiring diagram label adjacent

  to appliance wiring diagram label.

- Note: For controlled circuits having a capacity  

 equal to the load, use wiring diagram,

  Option #1.(10 Amps Max.) See Wire Diagram.

 - Note: For control circuits having a capacity  

 less than the load, use Option number #2.

 

1. Turn temperature control to lowest setting.

2. Turn off electrical power to heating appliance.

3. Disconnect controlled line voltage lead from the load terminal.

4. For Option #1 use a screw-on wire connector to join Adaptor Black & Blue lead to the controlled line voltage as in 3 above. For Option #2 join Adaptor Black lead only to the controlled line voltage and a Blue lead directly to120Vac line.

5. Join the remaining Adaptor Blue lead to the load.  

6. Connect Adaptor WHITE lead to the common side of the line voltage.

7. Connect damper wires BLACK (1), RED (2), BROWN (3) and BLUE (5) to Adaptor terminals 1, 2, 3 and 5 respectively.

8. Connect 24Vac continuous supply to Adaptor terminals 3 and 5.

9. Turn on electrical power supply. Damper will close. Note: ‘TEST/RUN’ manual switch shall be in the ‘RUN’ position.

10. Turn temperature control to call for heat. Damper will open and the appliance will operate normally.  

 

 Note: Where a low limit may allow operation of the burner or fuel valve when thermostat is not calling for heat, damper shall be used only in conjunction with Adaptor as shown.

 

Additional wire shall be of the same size as originally used when completing electric circuits.

 

Note: This marking is also on label to be affixed adjacent to appliance wiring diagram.
