Owner's Manual
Your new SunStat Dial thermostat is designed to control the voltage to
Please follow this manual for complete installation and operation instructions.
If you have any questions or comments, try calling Technical Support at
(800) 608-0562.
CAUTION:
This is a line voltage device that could cause serious injury or damage if
improperly installed.
1. Preparation
1. Unpack your thermostat and make sure everything is in good condition:
•
Thermostat
•
Floor sensor
•
Small screwdriver
•
Mounting screws
•
Wire nuts for wiring connections
If any parts are missing or damaged, contact the store where you purchased
this thermostat. Do not install a damaged part.
2. Gather the following tools and supplies:
•Phillips screwdriver, hole saw
•Electrical box for thermostat:

installing drywall materials.
c.

ALWAYS: Wire all circuits as Class 1, Electric Light and Power Circuits.
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.
CAUTION: The GFCI in this control does not protect against shock if both
bare conductors are touched at the same time.
2. Installation
Remove the Thermostat Face
1. Remove the thermostat 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. Be careful not
to bend or damage the 14-pin electrical
connector on the back of the Front
Module. bottom on the Front Module
and lift off.
Prepare the Wiring
1. Find a location for your thermostat. It is suitable for indoor use only, on
insulated or uninsulated walls. Locate it about 4
heat sources such as hot-water piping, heat duct, wall-mount lighting, and
direct sunlight to help prevent adversely affecting the thermostat.

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

5. The circuit breaker in the main circuit panel should be 15 amps maximum
to 15 amps, use a 20 amp maximum circuit breaker. Never exceed 15 amps
on this thermostat. You may consider using an arc-fault (AFCI) type circuit
breaker for additional protection.
6. Pull the power supply wiring into this box, leaving about 6 inches of wire.
7.
Note: The sensor wires should not be run in the same conduit as line voltage
wires to avoid possible interference. If the sensor lead wires are not long
enough, they may be extended an additional 15 feet (4.5 m) using minimum
20-gage 2-conductor wire or up to 50 feet (15 m) using shielded wire.
8. Mount the electrical box.
Connect Wires
1. Match and connect the two
wires marked "LINE1" and
"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
system lead wires and secure
these wires the same way.
5. Connect the house ground
wire to the green or bare lead
system.
6.
sensor wire into the "SENSOR"
terminals (1 and 2) and tighten
the screws. There is no polarity,
so it does not matter which wire
end goes into which terminal.
CAUTION: Before continuing,
make sure your power supply
voltage matches the voltage
system.

heating and damage to the system and may damage the control, other wiring,
29053V1 Relays
1. If you want to use your thermostat to drive a SunStat Relay(s) (ask
your dealer about this convenient way to control larger systems with one
thoroughly.
2. Pull 2-conductor wire, size 18- to 24-gage, through the wall from the
SunStat Relay, into this electrical box. This wire may be up to 100 feet (30 m)
in length from the thermostat to the last SunStat Relay installed.
3. Connect the wire ends into the "RELOUT" terminals (3 and 4) and tighten
the screws (Observe polarity of the wires when connecting to the SunStat
Relay).
Mount the Thermostat
1. Carefully fold and press the wires back into the electrical box. Do not use
the thermostat to push them in, as this may
cause connections to loosen and possible
failure.
2. Secure the thermostat Power Module into the
box with the mounting screws provided.
3. Carefully snap the Front Module onto the
Power Module. Be careful not to bend or
damage the 14-pin electrical connector on the
back of the Front 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 thermostat and turn up
the temperature to make sure it
is heating for a few minutes (section 3)
b. Test the GFCI (section 3).
