before removing cover

from Thermostat.

IMPORTANT

Do not remove battery tags to activate the

thermostat or wireless sensor until instructed to

do so.

For proper operation of the RF wireless

communication, when installing:

zAvoid locating thermostat or sensor near any

wireless or noise generating devices, particularly

radio devices that operate in the range of 418 to

428 MHz.

zBe sure that there are no electrical wires, metal

pipes or ductwork in the part of the wall chosen for

thermostat or sensor location

zAvoid locating the thermostat or sensor on a

concrete wall, metal junction box or metal plate.

zThermostat antenna wire must be installed into the

wall.Do not allow the antenna wire to be between

the thermostat and the wall.

zThermostat must have uninterrupted 24VAC for

proper communication.

System Power

Thermostat is received from the factory for system

power to be hardwired with a common wire connected to

terminal C. If no common wire is available, the thermo-

stat will use Power Stealing and must be configured.

See Thermostat 24VAC Requirement on page 5.

This device complies with Part 15 of the FCC Rules.

Operation is subject to the following two conditions:

(1) this device may not cause harmful interference, and

(2) this device must accept any interference received,

including interference that may cause undesired

operation.

Refer to Thermostat Configuration beginning on

page 10. If the remote sensor is to be an indoor

sensor, on Step 4, change Remote Off to Remote

On to enable the indoor sensor.

When the configuration menu is exited, the display

will indicate the indoor sensor is enabled.

4Provide battery power to remote sensor

and check sensor transmission

Connect wires to thermostat

Connect wires following standard wiring procedures.

Questions on wiring, see system diagrams on page 7.

24 VAC Requirement

The thermostat must have 24VAC to operate. If a

common wire is connected to terminal C, the

system is providing 24VAC to the thermostat and

the RC/PS switch (S7) should be in the RC posi-

tion. (See Figure 1 on page 5) Proceed to step 3.

If the thermostat does not have a common wire

connected to terminal C, the RC/PS switch must be

in the PS position to allow Power Stealing.

Antenna Wire – When installing the thermostat,

antenna wire must be installed into the wall for

proper communication between the thermostat

and the remote sensor.

Now, remove Battery Tag only from remote sensor

to provide power. Do not remove Battery Tag from

thermostat.

Enable the Learn mode of the remote sensor to

confirm that remote sensor is transmitting and

thermostat is receiving. Press and keys at

the same time and hold for approximately five

seconds. When keys are released, display will

show OFF and Learn. Press to change OFF to

ON. Then press both keys at the same time three

more times to exit the menu. The remote sensor

will be in the Learn mode and will transmit once

every 10 seconds for 10 minutes.

Place the sensor on the thermostat for the best

transmitting-receiving conditions.

Do not remove battery tags to power the thermostat or sensor

with batteries until instructed to do so. The thermostat requires

24voltsystem power to operatecorrectly.Leavingthebatteries

disconnected during installation and check out will verify sys-

tem power is present. If the thermostat goes blank, system

power is not reliable and will be corrected in the System Power

section below.

1. Remove the packing material from the thermostat and

sensor.

2. Pull the front cover of the thermostat straight off the base.

Forcing or prying will cause damage to the control.

selected wall locations and mark the location of all

mounting holes (Figure 1), and the hole for the thermostat

antenna wire illustrated in Figure 2.

4. Move base 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. Insert antenna wire into the wall and position base into

mounting position.

7. Fasten base loosely to wall, using two mounting screws.

Place a level against bottom of base (leveling is for

BatteryLocationBatteryLocation

BatteryLocation

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)Electric/Gas Switch (Fan Option)

Electric/Gas Switch (Fan Option)

The ELEC/GAS switch on the thermostat (Fig. 1) 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.

Typical wiring diagrams are provided below for the following systems:

Single Stage Heat/Cool systems

Multi-Stage Heat/Cool systems (No Heat Pump)

Heat Pump system, one compressor or one speed compressor with Aux. Heat

Heat Pump systems, two compressors or two speed compressor with Aux. Heat

Refer to the equipment manufacturers instructions for specific wiring information. After completing the connections configure

the thermostat in the Installer Configuration Menu to match your system type.
