Tools and supplies needed:
- No. 2 Phillips screwdriver
- Hole saw (if installing in an exisng wall)
- Wire strippers, wire cuers, and other electrical tools
- Electrical wall box (plasc or metal)*
*NOTE: A single-gang extra-deep box allows sucient space to connect 1 or 2
heang mats or cables. For 3 heang mats or cables, a 4-inch square extra-deep
electrical box with a single-gang “mud ring” is necessary. Alternately, a juncon
box may be installed to connect mulple heang mats or cables, then run
power supply wire from the juncon box to the control electrical box. See the
Installaon Instrucons provided with the oor heang system for more details.
Locang the Control
Find a suitable locaon for the control. It is designed for indoor dry locaon only.
It may be placed on an insulated or uninsulated wall, preferably an interior wall
to avoid overheang from outside sun heat. Keep it away from all water sources
such as sinks, showers, and bathtubs as well as heat sources such ashot-water
piping, heat ducng, wall-mount lighng, and direct sunlight. Locate it at a
suitable height, normally about 4-1/2’ to 5’ (1.4 m to 1.5 m) from the oor.
Mounng the Electrical Box
When mounng on an exisng wall, cut the opening for the electrical box for the
control. To make it easier to pull the wiring, wait to install the electrical box unl
aer all wiring is drawn into this opening.
When mounng on an open wall, secure the electrical box for the control to the
wall stud.
When mounng on an open wall, conduit from the electrical box to the oor is
recommended (check local codes for requirements) for addional protecon.
Install one conduit for the oor sensor. Install another conduit for the oor
heang system power leads. Refer to the Installaon Instrucons supplied with
the oor heang system for addional installaon details.
Wiring
CAUTION: Turn o power at the circuit breaker before doing any
electrical work.
House Wiring
A qualied person should run a dedicated circuit from the main circuit breaker
panel to the control locaon. If a dedicated circuit is not possible, it is acceptable
to tap into an exisng circuit. However, there must be enough capacity to handle
the load (amps) of the oor heang system being installed and any possible
appliance, such as a hair dryer or vacuum cleaner. Avoid circuits that have
ballasted lighng, motors, exhaust fans, or hot tub pumps due to
possible interference.
The circuit breaker should be rated 20 amps for total circuit loads up to 15 amps.
A 15 amp circuit breaker may be used for total circuit loads up to 12 amps. A
GFCI (ground-fault circuit interrupter) or AFCI (arc-fault circuit interrupter) type
circuit breaker may be used if desired, but is not necessary.
WARNING: Do not exceed 15 amps on this thermostat control. Doing so will
cause risk of re hazard and damage.
Pull power supply wiring to the control locaon. Leave about 6 to 8 inches (15
to 20 cm) of wire for connecons later. This wiring should be size 12 or 14 AWG
following appropriate local code requirements.
Floor Sensor
Pull the oor sensor wire up the wall (or conduit) to the control locaon, leaving
about 6 inches (15 cm) of wire for connecon later. The sensor wire may be cut
shorter if desired, but do not cut it shorter unl the sensor is fully installed
(see below).
Note: If the sensor wire is not long enough to reach the control locaon, it may
be extended an addional 15 feet (4.5 m) using minimum 20 AWG 2-conductor
unshielded wire, or an addional 50 feet (15 m) using shielded wire. When
using shielded wire, the “shield” must be connected to the lower sensor
terminal, nearest to Bus A. A juncon box may be required by local code for the
connecon to this extension wire.
Aer the oor heang system is completely installed according to its
instrucons, secure the thick sensor p to the oor. It must be located halfway
between heang wires and at least 1 foot into the heang area. Use hot-glue to
secure the sensor p and wire in place. Do not cross over a heang wire. Avoid
placing it in an area where heang wires are spaced further apart than the rest
of the oor, like a large gap between mats or cables. Avoid placing it in an area
where a heat duct or recessed light will cause improper measurements. Try to
avoid locang it where future items such as a clothes hamper or similar could
trap heat and cause improper measurement.
Finish securing the sensor wire along the oor and up the wall. At the control
locaon, cut the sensor wire shorter if needed, leaving at least 6 to 8 inches (15
to 20 cm) of wire for connecons later. Re-strip the sensor wire ends 1/8” to
3/16” (3 mm to 4.5 mm) long. If the ends are stripped longer than this they may
short-circuit resulng in an Err2 code.
Mat or Cable Power Leads
Pull the power lead wires from the oor heang system into the control
locaon. Leave about 6 to 8 inches (15 to 20 cm) of wire for connecons.

Wire Connecons
Match and connect the two wires marked “LINE1(L)” and “LINE2(N)” to the
house power supply wires using the wire nuts provided. Gently tug on the wires
to make sure they are secure, otherwise a wire could come loose and cause
failure. For added security, overwrap the connecons with electrical tape.
Match and connect the two wires marked “LOAD1” and “LOAD2” to the power
lead wires from the oor heang system. Secure these wire connecons the
same way with the appropriate size wire nut for the number of wire connected.
CAUTION: Make sure the house power supply voltage matches the voltage
rang of the oor heang system. Do not apply 240 VAC to a 120 VAC rated
system. Connecng the wrong voltage may cause overheang and damage
to the system, the control, oor coverings, etc.
Connect the house ground wire to the ground wire(s) from the oor heang
system. If the electrical box is metal, a short length of wire must be secured to
the electrical box from this ground connecon.
Insert the ends of the oor sensor wire into the terminals marked “SENSOR” and
snug the screws. It does not maer which wire goes into which terminal
