Installation

Installation must be performed by qualified persons, in accordance with local codes, ANSI/NFPA 70 (NEC Article 424) and CEC Part 1 Section 62 where applicable. Prior to installation, please consult the local codes in order to understand what is acceptable. To the extent this information is not consistent with local codes, the local codes should be followed. Regardless, electrical wiring is required from a circuit breaker or other electrical circuit to the control. It is recommended that an electrician perform these installation steps. Please be aware local codes may require this product to be installed by an electrician.

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.

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 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
SunStat® R4 Relays are used when more than 15 A must be controlled by one ConnectPlus thermostat. The ConnectPlus can connect wirelessly to the R4 Relay (see Operation > Wireless Pairing). If a wired connection is desired, follow these steps.

Pull 18 AWG to 24 AWG 2-conductor wire from the R4 Relay location to the ConnectPlus location
The wire may be up to 100 ft (30 m) long
Strip the wire ends to 1⁄8″ long
Refer to the R4 Relay manual for additional details

Home Automation System Rough-in Wiring

A short or 24 VAC applied between the AWAY and COM terminals will switch the thermostat into ‘Away’ mode.
Pull 18 AWG to 24 AWG 2-conductor wire from the home automation location to the ConnectPlus location
Strip the wire ends to 1⁄8″ long

Second Stage Rough-in Wiring

The ConnectPlus provides a dry contact output, rated at 30 VAC, 1 A, for second stage heat to be activated when the room temperature dwells below the setpoint. Room control mode only.
Pull 18 AWG to 24 AWG 2-conductor wire from the second stage control location to the ConnectPlus location
Strip the wire ends to 1⁄8″ long

ConnectPlus Wiring
Before connecting the wires to the back of the thermostat, detach the display front from the base. While holding the base section in one hand, with the other pull gently up holding the sides of the thermostat towards the bottom (near RESET button), pivoting away from the base.

Power Wiring

Connect the ground wire from the power supply to the ground wire from the floor heating power lead
If the electrical box is metal, use a short length of wire to connect the ground wires to the bonding screw
Connect the floor heating power lead conductors to the LOAD 1 and LOAD 2 terminals
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
Second Stage—connect to W2 terminals, refer to the second stage control instructions

Finish ConnectPlus Installation

Ensure all connections are secure
Carefully press the wires into the electrical box
Do not use the thermostat to push the wires
Secure the thermostat base to the electrical box with the screws included
Do not overtighten
Re-attach the display front
Line up the top edge with the base
Rotate the bottom towards the base and snap it into position

Operation

Power Up

Switch on the circuit power supply at the breaker
The ConnectPlus will load stored settings into memory

Heating Operation

By default, the ConnectPlus controls the heating system to maintain the floor temperature at the setpoint of 85°F (29°C). Room temperature control can be selected in the Temperature Settings. Floor and Room maximum settings are also available to limit temperatures.

GFCI Testing and GFCI Light Operation

Press the TEST button on the GFCI monthly to verify that it is operational. The GFCI RESET light will flash red. To resume normal operation, press the RESET button.
If pressing TEST does not display a flashing red GFCI RESET light, protection is lost, and the unit will need replacement.
If the GFCI RESET light continues to flash after pressing the RESET button, protection is lost, and the unit will need replacement.
If the GFCI trips during normal operation, press the RESET button to resume operation. If it trips again, the floor heating system should be inspected and tested by a qualified electrician.
If the GFCI TEST light stays on solid, a welded relay has occurred, and the unit will need replacement.
