heat pumps, PTACs, and fan coil equipment for the following

types of applications:

— 1H/1C conventional

— Up to 2H/1C heat pump

— 4 pipe fan coil (3 fan speeds)

— 2 pipe fan coil (3 fan speeds)

— 2 pipe fan coil with Auxiliary Heat (3 fan speeds)

— PTAC (Hi, Lo fan speed)

FEATURES

and set temperature and time—even in the dark.

• Menu-driven programming make setup effortless.

• Beautiful ergonomic design is smart and sophisticated

to match your customers’ lifestyle.

• Real-time clock keeps time during power failures and

automatically updates to daylight savings.

• “Saving Changes” notification lets you know when the

schedule changes have been saved.

• Change reminders let you know when to replace the

batteries.

• Holiday Override options allow you to override the

program schedule, as desired.

• Speedy same-schedule programming—no need to

copy multiple days.

• Armchair programming allows you to remove the

thermostat from the wall for programming.

• Programmable or non-programmable modes.

• Remote setback input for occupancy sensors or

timeclocks.

• VersaSpeed™ fan ramping algorithm and fan reset

algorithm (fan coil and PTAC applications).

If this control is replacing a control that contains

mercury in a sealed tube, do not place your old

control in the trash. Dispose of properly.

Contact your local waste management authority

for instructions regarding recycling and the proper

disposal of an old control.

INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow them

could damage the product or cause a

hazardous condition.

2. Check ratings given in instructions and on the product to

ensure the product is suitable for your application.

3. Installer must be a trained, experienced service

technician.

4. After installation is complete, check out product

operation as provided in these instructions.

CAUTION

Electrical Shock or Equipment Damage Hazard.

Can shock individuals or short equipment

circuitry.

Disconnect power supply before installation.

Select Thermostat Location

Select a location for the thermostat about 5 ft (1.5m) above the

floor in an area with good air circulation at average

temperature. See Fig. 5.

Fig. 5. Select thermostat location.

Do not install the thermostat where it can be affected by:

— Drafts or dead spots behind doors and in corners.

— Hot or cold air from ducts.

— Radiant heat from sun or appliances.

— Concealed pipes and chimneys.

— Unheated (uncooled) areas such as an outside wall behind

the thermostat.

Separate Wallplate from Thermostat

1. Separate the wallplate from the thermostat. See Fig. 6.

Fig. 6. Separate wallplate from thermostat.

Install Wallplate (See Fig. 7)

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.

WIRING

CAUTION

Electrical Shock Hazard.

Can cause electrical shock or equipment damage.

Disconnect power supply before connecting wiring.

IMPORTANT

— All wiring must agree with applicable codes,

ordinances and regulations.

— Use 18 gauge thermostat wire. Shielded cable is not

required.

NOTES:

— Refer to Table 5 for terminal designation

descriptions.

— See Fig. 11 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. 8.

Fig. 8. Terminal identifications for system type.

2. Loosen screw terminals used for the application.

3. Insert the wires into the terminal block and tighten each

screw terminal. See Fig. 9.

Fig. 9. Insert wires into terminal block.

4. Push excess wire back into the wall opening and restrict

wires to the shaded area. See Fig. 10.

5. Plug the wall opening with nonflammable insulation to

prevent drafts from affecting the thermostat.

Fig. 10. Restrict wires to shaded area of wire hole.

Table 5. 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. Sensor wires must have a cable separate from the

thermostat control cable.
