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.

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.

Refer to your Operating Manual

for programming and operation instructions A copy can be downloaded at www.pro1iaq.com

Replace AA Batteries when low battery indicator shows in display.

Insert 2 AA Alkaline batteries (included). High quality alkaline batteries are recommended.

Select Heat, Off, or Cool as needed. Select Fan On for

continuous operation or Auto to cycle fan with system.

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

Indicates the current room temperature

Time and day of the week / Outdoor Temperature if R251S is installed.

Low Battery Indicator: Replace batteries when this indicator is shown.

Program Menu Options: Show dierent options during programming.

Program Time Periods - Residential: Uses 4 time periods - WAKE, RETURN,

LEAVE & SLEEP. Commercial: Uses 2 or 4 time periods that appear in the text eld - Occupied & Unoccupied.

Staging Indicators: +1 will appear in the display when second stage of heat or cool is on. +2 will appear for the third stage of heat.

System Operation Indicators:

If these or the Fan indicator are ashing, it means that the system is in a delay of some type (compressor delay, cooling fan delay, staging delay).

Hold: is displayed when the thermostat program is permanently overridden.

Setpoint: Displays the user selectable setpoint temperature.

Important

The low battery indicator is displayed when the AA battery power is low. If the user fails to replace the battery within 21 days, the screen will only show the low battery indicator but maintain all functionality. If the user fails to replace the batteries after an additional 21 days (days 22-42 since rst “low battery” display) the setpoints will change to 55˚F (Heating) and 85˚F (Cooling). If the user adjusts the setpoint away from either of these, it will hold for 4 hours then return to either 55˚F or 85˚F. After day 63 the batteries must be replaced immediately to avoid freezing or overheating because the thermostat will shut the unit o until the batteries are changed.

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.

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.

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 17 of this manual to congure the thermostat for heat pump applications.

The second stage will turn on at 2x the swing setting. The second stage will turn o when 1x the swing is reached. For example, if the swing setting is .5 degrees for heating and the thermostat is set at 70˚F, the rst stage will turn on at approximately 69.5˚F. The second stage will turn on at 69˚F. The second stage will turn o at 69.5˚F and the rst will turn o at 70.5˚F. If the third stage is used, it will turn on at 3x the swing setting and turn o at approximately 2x the swing setting.

Filter Change & Other Reminders

If the lter change reminder is enabled, you will see FILT in the display when your air lter needs changed. FILT will be shown in the display after your system has run long enough to require an air lter change.

Resetting The Filter Change Reminder: When FILT reminder is displayed, you should change your air lter and reset the reminder by holding down the 3rd button from the left side of the thermostat for 3 seconds.

This thermostat also has other maintenance reminders (Humidity Pad, UV lamp, and IAQ Cell), that are reset with the same procedure.

Temporary & Permanent Hold Feature

Temporary Hold: The thermostat will display HOLD and RUN SCHED

on the bottom of the screen when you press the or key. If you do nothing, the temperature will remain at this setpoint temporarily for 4 hours. The program setpoint will then replace the temporary setpoint.

A Note About Programmable Fan:
