Mounting and Wiring

!WARNING

Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.

Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will damage thermostat and could cause personal injury and/or property damage.

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

Electric/Gas Switch (Fan Option)

This thermostat is configured from the factory to operate a heat/ cool, fossil fuel (gas, oil, etc.), forced air system. It is configured correctly for any system that DOES NOT require the thermostat to energize the fan on a call for heat. If you system is an electric heat or heat-pump system that REQUIRES the thermostat to turn on the fan on a call for heat, locate the ELEC/GAS switch on the back of the thermostat (see fig. 1) and switch it to the ELEC position. This will allow the thermostat to energize the fan immediately on a call for heat. If you are unsure if the heating/ cooling system requires the thermostat to control the fan, contact a qualified heating and air conditioning service person.

When the thermostat is configured for Heat Pump, the thermo- stat 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.

All wiring diagrams are for typical systems only. Refer to equipment manufacturers’ instructions for specific system wir- ing information.

!CAUTION

Take care when securing and routing wires so they do not short to adjacent terminals or rear of thermostat. Personal injury and/or property damage may occur.

Attach Thermostat Base to Wall

1.Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit.

2.Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 2 through 3).

3.Place base over hole in wall and mark mounting hole locations on wall using base as a template.

4.Move base out of the way. Drill mounting holes.

5.Fasten base loosely to wall, as shown in fig. 1, using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase.

6.Push excess wire into wall and plug hole with a fire- resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.

Battery Location

2 “AA” alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage. You must remove the battery tag to engage the batteries.

If “BATT” is displayed, the batteries are low and should be replaced. For best results, replace all batteries with new premium brand alkaline batteries such as Duracell® or Energizer®. To replace batteries, press system button to OFF, install the batteries along the top of the base (see Fig. 1). The batteries must be installed with the positive (+) end to the left.
