INSTALLATION

!WARNING

Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.

Remove Old Thermostat

A standard heat/cool thermostat consists of three basic parts:

1.The cover, which may be either a snap-on or hinge type.

2.The base, which is removed by loosening all captive screws.

3.The switching subbase, which is removed by unscrewing the mounting screws that hold it on the wall or adapter plate. Before removing wires from old thermostat, label each wire with the terminal designation from which it was attached. Disconnect the wires from the old thermostat one at a time. Do not let wires fall back into the wall.

8.Remove the battery tags in both the thermostat and sensor and replace the covers by lining them up with the base and pressing until they snap into place.

Guidelines for Thermostat/Sensor Locations

Locate the thermostat/sensor about 5 ft. above floor level on an interior wall in an area that represents the average room temperature.

Do not mount directly on or near HVAC equipment or other sources of electrical noise.

Avoid locations close to windows or near adjoining outside walls, doors leading outside, areas close to air registers or their direct air flow or areas with poor circulation like alcoves. Avoid locating the sensor on a concrete wall, junction box or metal plate. Make sure there are no electrical wires, metal, pipes or duct work in the part of the wall chosen for the sensor location.

Thermostat and indoor sensor are not approved for installation in unconditioned space.

Mounting Thermostat and Sensor

1.Remove the packing material from the thermostat and sensor.

2.Pull the front covers of the thermostat and sensor straight off the bases. Forcing or prying will cause damage to the controls.

3.Using the thermostat and sensor bases as templates, place them on the selected wall locations and mark the location of all mounting holes (Figure 1 and 3), and the hole for the thermostat antenna wire illustrated in Figure 2.

4.Move bases out of the way and drill the holes. If mounting holes drilled are too large and do not allow you to tighten base snugly, use the plastic screw anchors (provided) for secure mounting.

5.Make sure the remote communication receiver is plugged in properly to the thermostat and that the antenna wire is routed through the thermostat subbase as shown in Figure 2.

6.Fasten bases loosely to wall, using two mounting screws for each. Place a level against bottom of base (leveling is for appearance only and will not affect sensor operation) and then tighten screws.

7.In the thermostat location, push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting the thermostat operation.

Battery Location

The thermostat requires 2 "AA" alkaline batteries and the sensor requires 2 "AAA" alkaline batteries. Batteries are included at the factory with a battery tag to prevent power drainage. The battery tag must be removed to engage the batteries. For best results, replace batteries once a year with new premium brand alkaline batteries such as Duracell® or Energizer®.

Electric/Gas Switch (Fan Option)

The ELEC/GAS switch is factory set to the ELEC position. In this position, the thermostat will power the circulator fan on a call for heat. Electric heat systems may require the switch to be in the ELEC position.

If your system does not require that the thermostat power the circulator fan, this switch should be set to the GAS position. Typically, gas and oil heating systems do not require the thermostat to power the circulator fan during a call for heat. If your heat is gas or oil, the switch should be set to the GAS position.

When the thermostat is configured for Heat Pump, the thermostat will always power the circulator fan on a call for heat in the HEAT mode. The ELEC/GAS switch must be set to match the type of Auxiliary heat your system uses for proper operation in the EMERgency mode.
