Infloor Thermostat 29053 User Manual V1
Part# 29053
29053V1 Owner’s Manual
Your new Infloor Relay is designed to control the voltage to either a
120VAC or 240VAC resistive floor warming system. It must be driven by a
Infloor thermostat to operate.
Please follow this manual for complete installation and operation instructions.
If you have any questions or comments, try calling Technical Suppor t at
1-800-608-0562.
Make sure you are qualified and are familiar with house wiring. This is a
line voltage device that could cause serious injury or damage if improperly
installed.
1. Preparation
1. Unpack your Relay and make sure everything is in good condition:
Relay•
Small screwdriver•
Mounting screws•
Wire nuts for wiring connections•
If any parts are missing or damaged, contact the store where you purchased
this relay. Do not install a damaged part.
2. Gather the following tools and supplies:
•Phillips screwdriver, hole saw
•Wire strippers, “fish tape”, other electrical tools
•Electrical box for relay:
a. If you are connecting to power leads from only 1 or 2 floor warming
systems, you may use a single-gang, 31⁄2 inch deep box.
b. If you are connecting to power leads from 2 or 3 floor warming systems,
use a 4x4x21⁄8 inch or deeper box (not a 2-gang box) when your wall studs
are still exposed. Install a single-gang “mud-ring” cover on the box before
installing drywall materials.
c. For more than 3 floor warming systems or other layouts, you may need
to install a junction box. See the installation instructions for your floor
warming system for more information.
ALWAYS: Wire all circuits as Class 1, Electric Light and
ALWAYS: Wire all circuits with insulation rated 600V minimum.
ALWAYS: Mount this control only to a grounded metallic box or a
nonmetallic box.
ALWAYS: Use power supply wires suitable for at least 90°C.
CAUTION: High voltage – disconnect power supply before servicing.

Remove the Thermostat Face
1. Remove the Front Module from the
Power Module by opening the door and
loosening the screw.
2. Pull outward near the bottom on the
Front Module and lift off.
Prepare the Wiring
1. Find a location for your Relay. It is
suitable for indoor use only, on insulated or
uninsulated walls. Normally it works best at about 41⁄2 feet to 5 feet above the
floor on an inside wall. However, you may place it in any area where airflow is
not restricted, such as a large utility closet. Avoid placing it inside a cabinet
or closet that can confine heat. Avoid placing it near other heat sources such
as hot-water piping, heat duct, wall-mount lighting, and direct sunlight to help
prevent adversely affecting the control.
2. Turn off the power to the floor warming system at the main circuit panel
before doing any electrical work.
3. A qualified electrician should run a dedicated circuit from the main circuit
panel to the control location.
4. If a dedicated circuit is not possible, you may tap from another circuit in the
room. Make sure there is enough load capacity (amps) to handle the addition
of your floor warming system, and that it is NOT wired in series with any other
device, including other GFCIs.

5. The circuit breaker in the main circuit panel should be 15 amps maximum
for a floor warming system totaling 12 amps or less. For larger systems up to
15 amps, use a 20 amp maximum circuit breaker. Never exceed 15 amps on
this thermostat..
6. Pull the power supply wiring into this box, leaving about 6 inches of wire.
7. Pull the power lead wires from your floor warming system
up the wall, into
this box.
8. Mount the electrical box.
Connect Power Wires
1. Match and connect the
two wires marked “LINE1” and
from

supply
“LINE2” to the power supply
wires using the wire nuts
provided.
2. Gently tug on the wires to
make sure they are secure,
otherwise a wire could loosen
and cause failure.
3. Overwrap the wire nuts with
electrical tape to better secure
them to the wires.
4. Match and connect the two
wires marked “LOAD1” and
“LOAD2” to the floor warming
system lead wires and secure
these wires the same way.
5. Connect the house ground wire to the green lead wire(s) of your floor

CAUTION: Before continuing, make sure your power supply voltage matches
the voltage rating of your floor warming system.
Connecting 240V to a 120V floor warming system will cause overheating
and damage to the system and may damage the control, other wiring, floor
coverings, etc.
Connect Signal Wires From Thermostat
1. Pull 2-conductor wire, size 18- to 24-gage, through the wall from the
Infloor thermostat into this electrical box.
2. Connect the wire ends into the “RELIN” terminals(2 and 5) and tighten the
screws (observe polarity). See diagram below.
Connect Signal Wires to Other Infloor Relays
You may drive up to 10 Infloor Relays with one master Infloor thermostat.
1. Connect 2- conductor wire, size 18- to 24-gage, into the “RELOUT”
terminals(3 and 4) of the first Relay.
2. Pull this wire through the wall to the next Relay and connect to its “RELIN”
terminals(2 and 5).
3. Repeat this process for additional Infloor Relays.

Mount the Relay
1. Carefully fold and press the wires
back into the electrical box. Do not
use the control to push them in, as this
may cause connections to loosen and
possible failure.
2. Secure the Power Module into the box
with the mounting screws provided.
3. Carefully snap the Front Module onto
the Power Module.
4. Tighten the screw.
5. Switch on the power at the main
circuit panel.
NOTE to contractors: After installing
the thermostat, be sure to:
a. Switch on the relay(s)
b. Do a Quick Setup of the master thermostat (see instructions for your
Infloor thermostat)
c. Temporarily override the thermostat setpoint temperature, making
sure it signals this Relay to begin heating for a few minutes
d. Test the GFCI (section 3)
3. Operation
On/Off Switch
Your Infloor Relay should be turned off when
it is first installed.
1. Slide the on/off switch to the upper position,
turning the control on. A green light will show
on the front if power is applied. If the light is
amber, it indicates power is applied to the floor
warming system.
2. To turn the control off anytime, slide the
on/off switch to the lower position. No heating
will occur.

Test the GFCI
There is a GFCI (Ground Fault Circuit Interrupter) inside the Infloor Relay. It
is designed to help protect people from possible electrical shock if the floor
warming system has been damaged.
To make sure the GFCI is operating, test it after it is installed and once each
month:
1. Make sure the Relay is heating, showing the amber light on the front. You
may need to increase the setpoint temporarily on the master thermostat.
2. Press the GFCI Test button on the side of the control. A red light should
show next to the GFCI Test
power has been removed from the floor warming system. If any of these indi cators fail, turn off the Relay and replace it. Do not continue to use.
3. To reset the GFCI, slide the On/Off switch off and back on. If the GFCI does
not reset, turn the control off and go to section “4 Troubleshooting” for help.
