Fig. 2.

Fig. 2. Separate wallplate from thermostat.

Install Wallplate (See Fig. 3)

Mount the thermostat horizontally on the wall:

1. Pull the wires through the wire hole on the wallplate.

2. Position the wallplate on the wall with the arrow

pointing up. Level the wallplate for appearance only.

3. Use a pencil to mark the mounting holes.

4. Remove the wallplate from the wall and drill two

3/16 in. holes in the wall (if drywall) as marked. For

firmer material such as plaster, drill two 7/32 in.

holes. Tap the wall anchors (provided) into the

drilled holes until flush with the wall.

5. Pull the wires through the wire hole on the wallplate

and position the wallplate over the wall anchors.

6. Insert the mounting screws into the wall anchors

and tighten.

Fig. 3. Install wallplate.

WIRING

IMPORTANT

— All wiring must agree with applicable codes,

ordinances and regulations.

— Use 18 gauge thermostat wire. Shielded cable is

not required.

NOTES:

— Sensor wires must have a cable separate

from the thermostat control cable.

— Refer to Table 2 for terminal designation

descriptions.

— See Fig. 7 through 17 for wiring diagrams for

specific equipment applications.

1. Select set of terminal identifications that correspond

to your system type (conventional or heat pump).

(See Fig. 4).

Fig. 4. Terminal identifications for system type.

2. Loosen screw terminals used for the application.

each screw terminal. See Fig. 5.

Fig. 5. Insert wires into terminal block.

4. Push excess wire back into the wall opening and

restrict wires to the shaded area. See Fig. 6.

5. Plug the wall opening with nonflammable insulation

to prevent drafts from affecting the thermostat. Fig. 6. Restrict wires to shaded area of wire hole.

Table 2. Terminal Designation Descriptions.

NOTES:

1. When used in a single-transformer system,

leave metal jumper wire in place between Rc

and R. If used on a two-transformer system,

remove metal jumper wire between Rc and R.

2. Common wire is optional when thermostat is

used with batteries. When using separate

transformers for heating and cooling, the

common must come from the cooling

transformer.

3. If thermostat is configured for a heat pump in

the Installer Setup, configure changeover

valve for cool (O-factory setting) or heat (B).

4. Reference economizer literature for wiring

details. When set for economizer operation,

the A terminal provides the occupancy signal.

(Power indicates occupied.)

5. Sensor wires must have a cable separate

from the thermostat control cable.

Terminal “A” Wiring Details for Economizers

— Wire the A terminal to the W7212 “N” terminal, or the

W7459 “TR” terminal.

— When using dual transformers at the thermostat, the

heating transformer must power the economizer.

— The A signal is powered from the R terminal and

energizes the economizer to signal occupied status

and drive the damper to the set minimum position.

• 24 Vac direct connection with battery backup (AAA

alkaline).

Wiring 24 Vac Common

• Single-Transformer System—Connect the common

side of the transformer to the C screw terminal of the

thermostat wallplate. Leave the metal jumper wire in

place between Rc and R.

• Two-Transformer System—Connect the common side

of the cooling transformer to the C screw terminal of

the thermostat wallplate. Remove the metal jumper

wire between Rc and R.

Installing Batteries

1. Install three AAA alkaline batteries on the back of

the thermostat as marked. See Fig. 22.

Fig. 22. Installing batteries.

2. Locate and remove the tab labeled Remove. See

Fig. 23.

IMPORTANT

This tab must be removed in order to set the

real-time clock.

Fig. 23. Remove tab labeled REMOVE from

thermostat back.

Setting Calendar and Time

Setting Calendar

This thermostat is designed to, under normal use,

automatically keep current time and day in memory for up

to ten years once the calendar is set. There are two ways

to set the calendar for this thermostat:

SETTING CALENDAR WHEN THERMOSTAT IS FIRST POWERED

When the thermostat is first powered, the display is ready

to set the calendar and time. The thermostat proceeds

through a sequence of setup screens. See Fig. 24.

SETTING CALENDAR AFTER THERMOSTAT IS ALREADY

FUNCTIONING

See steps 1 through 4, in the Advanced Settings section,

to set year, month and day.

Fig. 24. Setting calendar and time after initial powerup.

Mount Thermostat to Wallplate

1. Align the terminal screw blocks with the pins on the

back of the thermostat.

2. Push the thermostat straight onto the wallplate until

it snaps into place. See Fig. 25.

aThe thermostat default setting is two period only. To use

four periods, change the appropriate setup parameter.

Minimum-Off Timer Compressor

Protection

The thermostat has an adjustable Minimum-Off Timer that

can be set from zero to five minutes (Factory Setting—five

minutes). The Minimum-Off Timer can be bypassed

through the Installer System Test or it can be bypassed

permanently by setting the Minimum-Off Timer to 0

minutes in the Installer Setup. The Minimum-Off Timer is

activated after the compressor turns off:

— If the thermostat is system powered (common wire),

the Minimum-Off Timer is also activated upon initial

startup and after power interruptions.

— If there is a call for cooling or heating during the

Minimum-Off Time, the thermostat displays “Wait.”

Table 6. Operation of Terminal A.

Heat Pump Temperature Lockouts

Dual Fuel Heat Pump and Outdoor Sensor

In this operation, there is no external fossil fuel kit (dual

fuel kit) installed; the thermostat controls this function:

1. Choose correct heat pump application in Installer

Setup Number 0170.

2. Choose Outdoor Temperature Sensor for Heat

Pump Temperature Lockouts Option in Installer

Setup Number 0340.

3. Choose appropriate Balance Point Temperature

in Installer Setup Number 0350.

OPERATION IN HEAT MODE ABOVE BALANCE POINT

(OUTDOOR TEMPERATURE)

When the outdoor temperature is above the selected

Balance Point Temperature (ISU 0350), only the

compressor operates and the fan (G terminal) energizes

when the thermostat calls for heat.

OPERATION IN HEAT MODE BELOW BALANCE POINT

(OUTDOOR TEMPERATURE)

When the outdoor temperature is below the selected

Balance Point Temperature (ISU 0350), only the Fossil

Fuel (auxiliary heat) operates and the fan (G terminal)

does not energize when the thermostat calls for heat.

Heat Pump with Auxiliary (Backup) Heat and

Outdoor Temperature Sensor

1. Choose correct heat pump application in Installer

Setup Number 0170.

2. Choose Outdoor Temperature Sensor for

Control Option in Installer Setup Number 0340.

3. Choose Compressor Lockout Temperature in
