Thank you for your confidence in our product. To obt ain the best resul ts from your inves tment, please read these instructions and acquaint yourself with your purchase. Follow the installation procedures carefully, and save these instructions for future reference.

SYSTEM COMPATIBILITY:

This thermostat can be used with most single-stage 24 V olt hydronic, and radiant underfloor heating applications up to 2 Amps. NOTE: this thermostat is system powered only, and requires 3 wires to the thermostat location for operation: 24V+ Power, 24V- Common, and Heat Activation Signal .

This thermostat cannot be used with: 3-wire zone valves (non self-closing upon power removal), 120/240 volt heating elements, cooling systems, or heat pumps. Ask your dealer for other LUXPRO thermostats to control those systems.

CAUTIONS AND WARNINGS:

• The electrical rating for this thermostat is 2.0 Amps.

• The thermostat contains parts that may wear out through use and are susceptible to failure if over-loaded or used in a manner other than as indicated in the documentation.

• Check unoccupied residences regularly to ensure that all systems are operating properly.

• Check any heating/air-conditioning system including this product before operation and at regular intervals.

• Electrical interference, static electricity, failure or substandard performance of batteries, wiring defects in the installation and/or characteristics of the connected HVAC devices may prevent the system from regulating heating and cooling as anticipated.

• The thermostat is a sensitive device and dropping the p roduct can cause d amage to critical components. If the product is drop ped or shaken viol ently during transport or installation then it should be replaced immediately.

• Persons with physical or mental limitations may not be able to promptly respond to a malfunction of the heating/air-conditioning system.

• All residents should be made aware of the potential in any system for malfunctions that could cause continuous heating or cooling and should be familiar with the operation and location of the heatin g/cooling appliance on/off switch.

• Read the instruction manual completely before installing the thermostat.

MERCURY WARNING AND RECYCLING NOTICE:

Mercury is considered to be a hazardo us material. If this product is replacing a thermostat that contains mercury in a sealed tube, contact you r local waste management authority for instructions regarding recycling and proper disposal. It may be unlawful in your state to place it in the trash.

INCLUDED FLOOR/SLAB TEMPERATURE SENSOR:

This thermostat kit contains a floor/slab temperature sensor that ge ts wired to the thermostat baseplate. The floor/slab sensor is an important component in the system, to properly control the heating output commands. The thermostat uses information from both the on-board internal room/air sensor, and also the wired remote floor/slab sensor during temperature control. The thermostat controls the room/air temperature to your desired setpoint value using the heat provided by the f loor, but also mai ntains the floor/slab temperature to within the MIN/MAX thresholds that you would like it to remain within.

The recommended location in the slab for this sensor is inside of an extra piece of radiant floor tubi ng at least 3-4 ft. (90-120 cm) in from the perimeter of the slab, with this tube at a depth of approximately 1 in. (25 mm) below the finished surface of the sla b. Please ensure that the sensor is positioned at l east 8 in. (20 cm) from any heated water tu bing within the floor/slab, so that the true temperature of the slab is being measured.

REMOVAL OF OLD THERMOSTAT:

1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on until all work is completed.

2. Remove the front portion of y our old thermostat to expose the wiring connections.

3. Write down the letters printed near each wire terminal that is used, and also the color of each wire that is connected to it.

4. Carefully remove the wires one at a time, and bend them in a manner so that they do not fall back insid e the wall. Do n ot allow bare wire ends to touch each other.

5. Loosen the mounting screws for the old thermostat and carefully remove it fro m the wall.

THERMOSTAT MOUNTING LOCATION:

On replacement installations, mount the new thermostat in place of the old one unless the conditio ns listed below suggest otherwise. On new installations, please follow these general guidelines:

. Mount the thermostat on an inside wall, about 5 ft. (1.5m) above the floor.

2. Do not loca te the thermostat where air circulation is poor such as in a corner, alcove, or behind a door that is normally left op en. Do not locate the thermostat where unusual heating or cooling conditions may be present, such as: direct sunlight, above a lamp, television, or radiator, or on a wall next to an exterior door or window.

3. Do not loca te in a damp environment, as this can lead to corrosion that may shorten thermostat life. If painting or construction work is sti ll ongoing, cover the thermostat completely or w ait until this wor k is complete before installation.

INSTALLATION NOTES:

• This thermostat is powered by the 24 VAC from the system, and must have a System Com mon wire (negative [-] side of the 24V transformer) atta ched to the “C” terminal adjacent to the “RH” w ire connection.

• If you only have three wires going to the thermostat location (RH, C, and W), then your hydronic zone valve will need to receiv e its Common conne ction from the transformer. If your hydronic zone valve cannot receive a Common Po wer connection directly from the transformer, the thermostat can provide Common Power to the zone valve using the optional “C” terminal output activation, but a f ourth wire must be added.

along with the “W” terminal for heati ng

INSTALLATION OF NEW THERMOSTAT:

1. Loosen the screw underneath the mi ddle of the thermostat housing, and separate the two halves by pulling the two bottom surfaces apart.

2. If needed, strip wire insulation leaving only 1/4 in. (6 mm) bare wire ends, and clean off any corro sion present.

3. Route the wires through the large opening in the new thermostat base plate, and attach your wir es using the diagr ams on the back page of this installation sheet.

4. When attaching the wires to the thermostat, ple ase ensure that th e bare wire ends are held all the way into the terminal block while the screws are being tightened.

COMPLETE THE INSTALL:

1. Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat’s normal operation.

2. Hold the base against the wall, and try to line up the screw holes from the prior thermostat to mount the base plate

3. If the previous holes cannot be used, hold the thermostat base against the wall so that it appears straight and level (position the base for best appearance) and mark for the new screw holes. Attach the base to the wall using the screws provided (use the supplied plastic anchors if needed when m ounting to a soft material such as drywall).
