Dual Room Damper Package Installation
To begin, first designate which room you will label as Room 1 (which will be the “off” room when there is no power to the
timer) and Room 2.
Step 1:
Place the
Bottom Return Air Plenum
where you would like the unit to sit. Now set the Indoor Air Handler on top of
the bottom plenum. Next, set the
Top Supply Air Plenum
on top of the Indoor Air Handler and fasten it down using metal
screws or strong adhesive tape.
Step 2:
Install the motorized dampers onto both the Bottom Return Air Plenum and Top Supply Air Plenum. Make sure to
fasten dampers with screws or adhesive tape. Do not push on damper flaps as you can damage the sensitive gear teeth on
the motor.
*MOUNT MOTORS ON TOP OF DAMPER, NOT BELOW
Step 3:
Open the front panel of the Indoor Air Handler. Take the relay assembly that should have came in a sealed
package in one of the damper boxes and remove the blue plug-in relay from the sub-base. This can be done by unlocking
the orange clip from the relay. Using the provided screw, mount the sub-base to the inside of the Indoor Air Handler cabinet
close to the control board.
Step 4:
Each wire on the relay assembly is labelled. Find the
“Air Handler R” (red
),
“Air Handler “G” (green)
and
“Air
Handler C” (white)
wires from the relay and connect loose ends to the R, G and C terminals by screwing onto the Indoor
Air Handler control board.
Step 5:
Using the 20’ roll of 2 Wire supplied (white), cut and strip individual lengths that will run from each motorized
damper to the mounted relay assembly. Now that you’ve cut your 2 Wire lengths, connect the white wire to the orange wire
on the damper using the Push-On connector. Next, connect remaining black wire to the yellow wire on the damper using the
Push-On connector. Repeat this step for all remaining dampers.
Step 6:
Take the opposite end of the 2 Wire from each damper and attach the white wire to the Push-On connector labeled
“Damper Commons (white)”
at relay assembly.
Step 7:
Once all the white wires are connected to the relay take the remaining black wires from “Room 1” and attach them
to the orange Push-On connector labeled
“Dampers Room 1 (black)”
at the relay. Repeat this step for “Room 2” only this
time attache to the orange Push-On connector labeled
“Dampers 2 (black)”
at the relay.
Step 8:
Thermostats;
A-
Connect red wire from thermostats in “Room 1” to yellow Push-On connector labeled
“Thermostat 1 (red)”
at relay.
B-
Connect white sire from thermostat in “Room 1” to Push-On connector labeled
“Damper Commons (white)”
at relay.
*Used previously in Step 6
C-
Connect green wire from thermostat in “Room 1” to Push-On connector labeled
“Thermostat 1 (green)”
at relay.
D-
Connect black wire from thermostat in “Room 1” to screw down terminal
“Y”
on the control board of the Indoor Air
Handler.
E-
Connect orange wire from thermostat in “Room 1” to screw down terminal
“W1”
on the control board of the Indoor Air
Handler.
F-
Now we’ll setup “Room 2” thermostat. Connect red wire from thermostat “Room 2” to yellow Push-On connector labeled
“Thermostat 2 (red)”
at relay.
G-
Repeat steps B-E for remaining wires for the “Room 2” thermostat.
Step 9:
Plug relay onto the sub-base making sure the diagram picture on the relay is facing the orange clip so that it will
lock securely. Lastly, plug the
“120V Flip Timer”
plug into your timer (not provided). That’s it, you’re done!
