INSTALLATION

REMOVE OLD THERMOSTAT

1.Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected.

2.Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly.

3.Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat.

4.Disconnect the wires from old thermostat one at a time. DO

NOT LET WIRES FALL BACK INTO THE WALL.

5.Install new thermostat using the following procedures.

ELECTRIC HEAT OR SINGLE-STAGE

HEAT PUMP SYSTEMS

Read entire paragraph before setting electric heat switch. If you are unsure of your application, contact a qualified serviceperson.

If you have a single-stage heat pump system, OR your system uses central electric heat, where the blower is energized by a separate circuit through the fan relay (meaning that the fan turns on immediately on call for heat), then the switch on the back of the thermostat base must be moved to the “ELECTRIC” position (see fig 1). If the thermostat is energizing electric heat sequencers, the switch MUST remain in the “GAS” position.

If you must move the switch to the “ELECTRIC” position (to the left), use a small screwdriver or pencil.

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. If necessary, move the electric heat switch (see ELECTRIC HEAT SYSTEMS, above).

2.Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 3 through 10).

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. 2, 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.

HEATING SYSTEMS

This thermostat requires 3 “AA” alkaline batteries to operate. Batteries are installed in the thermostat at the factory with a battery tag to prevent power drainage. You must remove the battery tag to engage the batteries and provide power to the thermostat.

If the word BATTERY is displayed, the batteries are low and should be replaced with fresh “AA” Energizer® alkaline batteries. To replace batteries, install the batteries along the top of the base (see fig. 2). The batteries must be installed with the positive

(+) ends to the left.

This thermostat is set to operate properly if you have a forced- air heating system. If you have a hydronic heating system (a system that heats with hot water or steam), you must set the thermostat to operate properly with your system. While in the HEAT mode, change the setting by pressing SET TIME/SET TEMP and VIEW PRGM buttons at the same time until the correct setting is displayed (A for forced air; H for hydronic systems). If there is a loss of battery power, or when you change batteries, you must repeat this operation once battery power is restored.
