This Adaptor ADP-1103-TW5 is an automatic
control switch which is designed but not limited
to accommodate two separate exhaust fans in
a dwelling having one furnace and (if used) a
replacement air damper. A controlled 120Vac
signal from one exhaust fan and or a 24Vac
signal (or dry contacts) from a second exhaust
fan will simultaneously turn on the furnace
circulation fan and open the replacement air
damper. Added is a relay to also open the
damper during furnace firing.
Fitness of this Adaptor/Damper combination,
to satisfy air supply requirements for fuel fired
appliances during operation of the in-
terconnected 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-1103-TW5

One Relay DPDT: Relay Coil - 24Vac.
All Contact Points - 24Vac - 5 Amps.
-Adaptor line voltage leads, connected to the
exhaust fan controlled line, shall be suitably
cabled, fastened and enclosed in suitable
raceways.
-Refer to local and applicable codes.
-Always conduct a thorough check-out after
installation is complete.

and warnings on each label.
Connecting the Adaptor ADP-1103-TW5 to a
controlled 120Vac Designated Ventilation
Exhaust Fan circuit and heating appliance.
1. Turn off electrical power supply to both the
exhaust fan and furnace circuits.
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(G T ).
(b) Connect Adaptor terminal #4(G F ) 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 1103-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 which will
simultaneously turn on the furnace circulation fan.
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 pen 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 pen type, it will remain
closed at this time. If damper is a Power Close
type, it will close at this time.
If the HAC Fresh Air Damper is to also open
during furnace firing:
12. Turn off the main power to the furnace and
connect Adaptor terminal #9 to Furnace (W)
and connect Adaptor terminal #8 to furnace (C)
or to furnace ground screw.
13. Turn power on to the furnace and turn the
thermostat for the furnace to fire. Damper will
open during the firing cycle of the furnace and will
close to save energy when the furnace fire stops.
