Section 3. Physical Installation

1A Temperature Sensing Considerations

The thermostat sensor is designed for installation in climate controlled living spaces. It is recommended to place the sensor in central locations with good circulation. Avoid exterior walls and areas near windows, doors, vents or concealed pipes or chimneys.

YES	NO
NO
5 FEET
[1.5 METERS]

1B	Wireless Reception Considerations
If enabling wireless, choose a mounting location that ensures adequate signal strength.
A wireless device may have significantly different signal strengths if its position chang-
es relative to other wireless devices. If the thermostat shows poor signal strength, you
may be able to improve the signal strength by moving the thermostat a short distance		Wireless
in any direction.
Considerations to Maximize Signal Strength:

•Do not mount the thermostat more than 30 feet from the wireless router (through no more than three interior walls).

•Do not mount the thermostat in areas where electromagnetic emissions from other devices, appliances or wiring can interfere with the thermostat’s communication. (i.e. wireless phones, security systems, wireless internet cameras)

•Do not mount the thermostat in recessed areas, near metal objects, or near structures. (i.e. doors, appliances, entertainment centers or shelving units)

•Do not mount the thermostat closer than 2 inches to any pipes, duct work, or other metal obstructions.

•Do not have metal obstructions, concrete or brick walls between the thermostat and the wireless router it will be connected to.

NOTE: See the User’s Guide for wireless setup information (weather, multi-system and remote software update functionality).

2 Removing Sub-Base Wall Plate

Remove sub-base plate from the thermostat by inserting a small flat blade screwdriver into the notch at each of the four tabs as shown.

Gently pry the sub-base away from the the thermostat.

NOTE: This tight fit is normal and ensures that the thermostat is held securely to the sub-base when mounted on the wall.

3 Mounting Sub-Base to Wall

Be sure wires are routed through the center of the base plate and are long enough to connect to terminals.

Select and mark three holes.

NOTE: The three hole locations indicated at right are recommended. The top location is an optional mounting screw location.

A level may be used to ensure professional appearance.

Locations

4A Mounting to Studs

Attach base to wall using 3 screws provided. The locations indicated provide the most secure mounting and are recommended.

NOTE: Since moderate force is required when removing the thermostat from the sub-base, the subbase must be securely attached to the wall.

Do not overtighten screws to avoid damaging the sub-base.

4B Mounting to Drywall

If mounting to drywall, supplied SnapSkru® connectors must be used to mount the thermostat sub-base to the wall. These connectors will ensure that the control is adequately supported.

NOTE: Since moderate force is required when removing the thermostat from the sub-base, a firmly mounted sub-base is essential.

1) Press tip of SnapSkru® anchor into drywall using #2 Phillips screwdriver or screw gun. Drive anchor clockwise into drywall until anchor stops flush with wall.

2) Place sub-base over anchor and insert screw.

3) Tighten screw flush with subbase. Screw “pops” open anchor, locking anchor on wall.

Do not overtighten screws to avoid damaging the sub-base.
