Important Safety Information

• This is a safety-alert symbol. The safety-alert symbol is shown alone or used with a signal word (DANGER, WARNING, or  a pictorial and/or a safety message to identify hazards.
• When you see this symbol alone or with a signal word on your equipment or in this manual, be alert to the potential for death or serious personal injury.
• This pictorial alerts you to electricity, electrocution, and shock hazards.
• This symbol identifies hazards which, if not avoided, could result in death or serious injury.
• This symbol identifies practices, actions, or failure to act, which could result in property damage or damage to the equipment.

Power Supply

• 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.

Bottom Plate Work

Drill or chisel holes at the bottom plate as indicated. One hole is for routing the power lead conduit and the other is for the thermostat sensor. These holes should be directly below the electrical box(es).

SunStat Sensor Installation

• The SunStat sensor can be installed with or without an electrical conduit depending on code requirements.
• A 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 knockout 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.

• For 120 VAC connections, connect the power supply black (L) wire to the L terminal and the white (N) wire to the N terminal
• For 240 VAC connections, connect one of the power supply wires to the L1 terminal and the other to the L2 terminal

Low Voltage Wiring

Sensor, R4 Relay, Home Automation, and Second Stage connections are made to the terminal block by inserting the wires into the openings and tightening the screws. Three holes are provided for wire access from the back. Wires must be routed in the channel to the right of the terminal block so that the display front can be re-attached. Any low voltage wiring that passes through the inside of the electrical box must be rated at least 90°C 300 V.

• Sensor—connect to the SENSOR terminals, not polarity sensitive
• R4 Relay—connect to RELAY and COM terminals, matching connections on the R4 Relay
• Home Automation—connect to AWAY and COM terminals, refer to home automation control instructions
