A trained, experienced technician must install this product.

Carefully read these instructions. You could damage this product or cause a hazardous condition if you fail to follow these instructions.

Una version en espanol de este

manual se puede descargar en la pagina web de la compania.

Do not install thermostat in these locations:

• Close to hot or cold air ducts

• That are in direct sunlight

• With an outside wall behind the thermostat

• In areas that do not require conditioning

• Where there are dead spots or drafts (in corners or behind doors)

• Where there might be concealed chimneys or pipes

Installation Tip

Pick an installation location that is easy for the user to access. The temperature of the location should be representative of the building.

Horizontal Mount

Vertical Mount

Installation Tip: Electrical Hazard

Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

For horizontal mount put one screw on the left and one screw on the right.

For vertical mount put one screw on the top and one screw on the bottom.

Mercury Notice

All of our products are mercury free. However, if the product you are replacing contains mercury, dispose of it properly. Your local waste management authority can give you instructions on recycling and proper disposal.

Align the 4 tabs on the subbase with corresponding slots on the back of the thermostat, then push gently until the thermostat snaps in place.

Note: To ensure a solid t between the thermostat and the subbase:

1. Mount subbase to a at wall

2. Use screws provided

3. Drywall anchors should be ush with the wall

4. Wires should be pushed into the wall

Thermostat Quick Reference

Battery Installation

Battery installation is recommended even if the thermostat is hardwired (C terminal connected). When the thermostat is hardwired and batteries are installed, the thermostat will activate a compressor delay of 5 minutes when it detects a power outage from the hardwired power supply.

Important:

High quality alkaline batteries are recommended. Rechargeable batteries or low quality batteries do not guarantee a 1-year life span.

To release battery cover press nger bevel on the left side and lift the cover to access batteries.

Wiring

Caution: Electrical Hazard

Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

Wiring

If you are replacing a thermostat, make note of the terminal connections on the thermostat that is being replaced. In some cases the wiring connections will not be color coded. For example, the green wire may not be connected to the G terminal.

Loosen the terminal block screws. Insert wires then retighten the terminal block screws.

Place nonammable insulation into

the wall opening to prevent drafts.

Wiring Tips

C Terminal

The C (common wire) terminal does not have to be connected when the thermostat is powered by batteries.

Wire Specications

Use shielded or non-shielded 18-22 gauge thermostat wire.

Simple operating instructions are found on the back of the battery door.

Warning:

All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code.

Installation Tip

Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from tting on the subbase correctly or cause system operation issues.

Max Torque = 6in-lbs.

Note:

In many heat pump systems with no emergency heat relay, a jumper can be installed between E and W2 to turn thermostat into a single stage control for Emergency Heat Operation.

Setpoint: Displays the user selectable setpoint temperature.

Terminal Designations

This thermostat is shipped from the factory to operate a conventional heating and cooling system. This thermostat may also be congured for a heat pump system. See the “heat pump” conguration step on page 14 of this manual to congure the thermostat for heat pump applications.

Thermostat Quick Reference

Important

The low battery icon is displayed when the AA battery power is low. Whenever the thermostat detects low battery voltage from the AA batteries, the low battery icon will begin ashing on the screen for 21 days (if the batteries are not changed). If the batteries are not changed 22 days after the thermostat detects low battery voltage, the thermostat screen will only show the ashing battery icon until buttons are pressed. If the batteries are not changed 43 days after the thermostat detects low battery voltage, the thermostat screen will only show the ashing battery icon until buttons are pressed and the set points will oset to 85°F/29°C in cooling and 55°F/13°C in heating. At this stage, set point changes can be made temporarily but, the set points will change back to defaulted values after a 4-hour period. The thermostat will continue to perform this low battery ashing, temperature oset condition until the internal voltage threshold is reached. When the thermostat internal voltage threshold is reached, all relays will be opened and the thermostat will become inoperable until new batteries are installed.

Programming

All our programmable thermostats are shipped with an energy saving default program. You can customize this default program by following the instructions in the set program schedule section starting on page 24.

Your thermostat can be programmed to have each day of the week programmed uniquely (7 days), all the weekdays the same with a separate program for Saturday and a separate program for Sunday (5+1+1), or non-programmable. For the 7-day and 5+1+1 programming modes, there are three time period options.

1. “4” Residential (WAKE, LEAVE, RETURN, SLEEP)

2. “2C” Commercial (OCCUPIED, UNOCCUPIED)

3. “4C” Commercial (OCCUPIED 1, UNOCCUPIED 1, OCCUPIED 2, UNOCCUPIED 2)

This thermostat has a programmable fan feature, which allows you to run the fan continually during any time period.

A Note about IAQ Mode

This programmable/selectable mode will operate the fan 1-4 cycles per hour, 1-45 minutes per cycle. Once programmed in tech setup, to enable this mode select “IAQ” with the fan key. Disable this mode by selecting “ON” or “AUTO” with the fan key.

To customize your 7 day 4 time period Program schedule, follow these steps:

Monday:

1. Select HEAT or COOL with the SYSTEM key. Note: You have to program heat and cool each separately.

2. Press the MENU button (If menu does not appear rst, press RUN SCHED).

3. Press SET SCHED. Note: Monday is displayed and the

WAKE/OCC1 icon is shown. You are now programming the WAKE/OCC1 time period for that day.
