operating at more than 150 V to ground.
Power Supply
Pull power supply wiring to the control location.
• Leave about 6 to 8" (15 to 20 cm) of wire for connections.
•
This wiring should be size 12 or 14 AWG, in compliance with
local code requirements.
• A qualified person should run a dedicated circuit from the main
circuit breaker panel to the control location. If a dedicated
circuit is not possible, it is acceptable to tap into an existing
circuit. However, there must be enough capacity to handle the
load (amps) of the floor heating system being installed, and any
appliance likely to be used on the circuit such as a hair dryer
or vacuum cleaner.
•
Avoid circuits that have ballasted lighting, motors, exhaust fans,
or hot tub pumps to reduce the likelihood of 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, but is not necessary.

The following cautions must be observed:
SunStat Sensor Installation
• The SunStat sensor can be installed with or without electrical
conduit depending on code requirements. Conduit is recommended
for added protection against nails and screws.
•
Do not place the sensor in the same conduit as the power leads
to avoid possible interference. Open a separate knock-out in the
bottom of the thermostat box. Feed the sensor (and conduit, if
used) through the knock-out, down through the cut-out in the
bottom plate, and out into the floor where the heating cable will
be installed.
•
If the sensor wire needs to be secured to the wall stud, wait
until after the wire or mat and sensor are completely installed
on the floor.
• At the sensor location, measure at least 1' into the heated area.
Mark the spot where the sensor will be attached to the floor. Be
sure to place the sensor exactly between two of the heating wires.
Ensure the sensor wire does not cross over any heating wires.
•
Do not locate the sensor outside the heating area or in a gap
between heating wires that is wider than the rest of the floor.
Do not locate the sensor where direct sun, hot-water piping,
heat duct, or lighting below will cause inaccurate temperature
reading. Do not locate the sensor where an insulating item such
as a rug is likely to be placed.
• To make sure the sensor tip does not create a high spot in the
floor, it may be necessary to chisel a channel into the floor and
lay the sensor tip into the channel. Hot glue the tip into place.
• Do not cut the sensor wire or remove the black cable protector.
Strip the wire ends to 1/8" long.
Floor Heating Mat or Cable Power Lead Installation
• The shielded power lead can be installed with or without electrical
conduit (recommended for added protection against nails or
screws), depending on code requirements.
•
Remove one of the knock-outs in the electrical box to route the power
lead. If electrical conduit is not required by code, install a wire collar to
secure the power leads where they enter the box. If conduit is required
by code, install 1/2" (minimum) conduit from the bottom plate up to the
electrical box. For multiple power leads (multiple cables), install
3/4" conduit.
• Secure a steel nail plate over the cutout in the bottom plate to
protect the wires against baseboard nails later.
SunStat Relay Rough-in Wiring
A SunStat Relay C3 is used when more than 15 amps must be
controlled by one SunStat thermostat. The SunStat Connect is only
compatible with the SunStat Relay C3. Do not use other models.
• Pull 18 AWG to 24 AWG 2-conductor shielded wire from the
relay location to this control location. The wire may be up to
100' (30 m) long.
• Strip the wire ends to 1/8" long.
Refer to the instructions provided with the SunStat Relay C3 for
additional details.
Home Automation System Rough-in Wiring
A short or 24 VAC applied between the Away and Com terminal
will switch the thermostat between the 'Away' temperature and
regular operation.
• Pull 18 AWG to 24 AWG 2-conductor shielded wire from the home
automation control to this control location.
• Strip the wire ends to 1/8" long.

Sensor, relay and home automation connections are made to the
terminal block by inserting the wires into the square openings
and tightening the screws on the side.
• Connect the sensor wires to the SENSOR terminals on the
thermostat. These connections are not polarity sensitive.
•
For a SunStat Relay C3, connect 2 wires from the relay to the
Com and Relay terminals on the thermostat. Ensure the Com
wire at the relay is the same conductor connected to the Com
terminal on the thermostat.
•
Connect the Away and Com terminals to the appropriate
conductors from a home automation system. Refer to the
instructions for the home automation control before making
these connections.

Finish Thermostat Installation
• Ensure all connections are secure.
• Carefully press the wires back into the electrical box. Do not
use the control to push them.
•
Use the included screws to attach the thermostat base to the
electrical box. Do not overtighten.
•
When re-attaching the display front, line up the top edge with
the base, then rotate the bottom towards the base. Ensure
the pins are not bent when connecting.
Make sure the wire connections are secure by gently tugging
on them. Otherwise, arcing could occur, causing dangerous
overheating and a possible fire hazard. For added security,
overwrap each wire nut connection with electrical tape.
While holding the base
section in one hand,
pull the lower half of the
display front towards
you to pivot it away from
the base.
