Failure to read and follow all safety and use information can result in death, serious personal injury, property damage, or damage to the equipment.
Keep this manual for future reference.
The antenna used for this radio must be properly installed and maintained and must provide a separation distance of at least 7.9 inches (20 cm) from all persons.
This device complies with Part 15 of the FCC Rules and with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
This is a safety-alert symbol. The safety-alert symbol is shown alone or used with a signal word (DANGER, WARNING, or CAUTION), 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.
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.
The following cautions must be observed:
ALWAYS install the floor sensor included with the thermostat.
NEVER put the system into full operation until the tile or flooring installer verifies all cement materials are fully cured (typically two to four weeks after installation).
ALWAYS use insulated copper wires rated for 90°C (194°F) and 600 V minimum. Do not use aluminum.
ALWAYS wire all circuits as Class 1, electric light & power circuits.
ALWAYS mount the thermostat to a grounded electrical box.
ALWAYS seek help if a problem arises. If ever in doubt about the correct installation procedure, or if the product appears to be damaged, the factory must be contacted before proceeding with the installation.
To prevent the risk of personal injury and/or death, make sure power is not applied to the product until it is fully installed and ready for final testing. All work must be done with power turned off to the circuit being worked on.
To reduce the risk of electric shock, do not connect to a circuit operating at more than 150 V to ground.
Pull power supply wiring to the control location.
Make sure 120 VAC is supplied to 120 VAC cables and 240 VAC is supplied to 240 VAC mat or wire. Otherwise, dangerous overheating and a fire hazard could result. Do not exceed 15-amps on this control.
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.
A short or 24 VAC applied between the AWAY and COM terminals will switch the thermostat into 'Away' mode.
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.
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.
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.
Make sure the wire connections are secure by gently tugging on them. Otherwise, arcing could occur, causing dangerous overheating and a possible fire hazard.
Make sure the mortar has had time to fully cure before operating the system for more than a brief test.
