INSTALLATION O THIS ADAPTOR SHALL BE IN
ACCORDANCE WITH THE REQUIREMENTS O
THE AUTHORITIES HAVING JURISDICTION
Refer also to HOYME Installation Instructions:
Combustion Air Control Damper, Series HOM;
Replacement/Ventilation Air Control Damper,
Series HAC; and Adaptor ADP- 1101- 05A.
ADP-0241-10A
4” x 5” x 2 1/2”
101 x 127 x 64 mm
his Relay Adaptor may be used as an automatic
switch having a 24Vac Coil and 120Vac points to
control a line voltage circuit for up to a 10 amp
draw such as a 120Vac exhaust fan. All the points
can also be used for 24Vac switching. (See wire
diagrams on next page.)
A typical application where all the points are used
for 24Vac switching may occur when dry points are
used at the exhaust fan switch. When the exhaust
fan switch is turned on, the furnace fan and the
fresh air damper, if used, will open simultaneously.
he fresh air damper, however, will not open for
furnace firing.
If the damper is required to open when the
appliance fires:
a) Refer to wiring diagram (next page) showing the
Power Close Damper with Relay;
- or -
b) Use a regular fresh air damper with an ADP-
0242-05A and follow its Installation Instructions;
- or -
c) If controlled line voltage is available from the
exhaust fan, use Adaptor ADP-1102-TWP and
follow its installation instructions.
itness 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.: ADP-0241-10A; comes with two relays with
coils in parallel and therefore acting as one relay.
DPD - Coil-24Vac. Points-24Vac-5Amps
SPD - Coil-24Vac. Points 120Vac-10Amps
- One adaptor is required for each heating
appliance.
- Adaptor line voltage leads, connected to the
appliance shall be suitably cabled, fastened and
enclosed in suitable raceways.
- Refer to local and applicable codes.
- If an auxiliary transformer is required, use an
approved 24Vac transformer of adequate capacity.
- Supply for the transformer primary shall be taken
from the line voltage supply of the appliance.
- Always conduct a thorough check-out after
installation is complete.
- Affix appropriate labels and follow
instructions and warnings on each label.
1. Install motorized air control damper as per
instructions supplied with it. Satisfactory
operation of the damper is recommended
before interconnecting Adaptor.
2. urn off electrical power supply to the
appliance.
3. Connect Adaptor line voltage leads to fan motor
circuit as per wiring diagram and applicable codes.
4. Connect 24Vac Damper terminal wires to
appropriate Adaptor, transformer and control
switches. (See damper wiring diagram for proper
circuit.)
5. urn on electrical power to 24Vac transformer.
If 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.
6. urn on selected switches at least 3 times to
verify the intended operation of selected circuits.

SCHEMATIC WIRE DIAGRAM O
ADAPTOR ADP- 0241-10A
Note: his marking is also on the cover of the
Adaptor unit as well as on a label to be placed
next to the wiring diagram of the appliance.
his Adaptor uses a 24Vac Coil SPD to
develop a 10A capacity for 120Vac if needed
and a 24Vac Coil DPD to develop multiple
contact points for 24Vac. Coils are connected
in parallel and therefore act as one relay.

Schematic Wire Diagram of ADP-0241-10A
Activated by an Exhaust an Auxiliary Relay
Switch and/or Thermostat Controlling a
urnace an, and a Power Close Fresh Air
Damper with Relay .
Damper also opens during furnace firing.
Suggestion: Use Fresh Air Damper with Relay
HAC – 0X11 – OPC where X = Diameter of Damper,
1 = Relay, PC = Power Close
Note: For PC damper only, a toggle switch in
series with 24Vac electrical supply line to the
Damper will cause it to open as required.
* Note: For PC damper without relay and if
adding a Combustion Air Damper, re-connect
Fresh Air Damper from furnace ‘C’ to Green
wire of the Combustion Air Damper. Both
dampers will open during firing of the furnace.
* Note: If existing ventilation relay (auxiliary
relay switch) cannot be located, relay wires
presently connected to ‘R’ and ‘G’ of the furnace
are to be re-connected to #3 of ADP and ‘C’ of
the furnace. ADP #6(G F) is then to be
connected to ‘G’ of the furnace and hermostat
wire ‘G’ is to be connected to #7(G ) of the
Adaptor.
