Installation Tips

Wall Locations
The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.

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.

Do not install thermostat in 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

Subbase Installation

1. Horizontal Mount
2. Vertical Mount

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

Installation Tip: Electrical Hazard
Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

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.

Mount Thermostat

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.

Battery Installation

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

About The Badge
All of our thermostats use the same universal magnetic badge. Visit the company website to learn more about our free private label program. Gently slide a screwdriver into the bottom edge of the badge. Gently turn the screwdriver counter clock-wise. The badge is held on by a magnet in the well of the battery door. The badge should pry off easily. DO NOT USE FORCE.

Thermostat Quick Reference

Getting to know your thermostat

1. LCD Display
2. Fan Switch
3. System Switch
4. Easy change battery door
5. Temperature Setpoint Buttons
6. User Buttons

1. Indicates the current room temperature
2. Time and day of the week
3. Low Battery Indicator: Replace batteries when this indicator is shown.
4. Program Time Periods: This thermostat has 4 programmable time periods per day.
5. System Operation Indicators: ON will display when the COOL or HEAT is on. Compressor delay feature is active if Flashing.
6. Hold is displayed when the thermostat program is permanently overridden.
7. Setpoint: Displays the user selectable setpoint temperature.

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 flashing 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 flashing 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 flashing battery icon until buttons are pressed and the set points will offset 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 flashing, temperature offset 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.

Wiring

1. 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.
2. Loosen the terminal block screws. Insert wires then retighten terminal block screws.
3. Place nonflammable insulation into wall opening to prevent drafts.

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

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

Terminal Designations

• C Common wire from system transformer
• O Heat pump changeover valve energized in cooling
• B Heat pump changeover valve energized in heating
• W Heat relay
• RH Transformer power for heating
• RC Transformer power for cooling
• G Fan relay
• Y Compressor relay

Wiring Tips

RH & RC Terminals
For single transformer systems, leave the jumper wire in place between RH and RC. Remove jumper wire for two transformer systems.

Heat Pump Systems
If wiring to a heat pump, use a small piece of wire (not supplied) to connect terminals W and Y.

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

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

Installation Tip: Do not overtighten terminal block screws, as this can damage the terminal block. A damaged terminal block can keep the thermostat from fitting on the subbase correctly or cause system operation issues. Max Torque = 6in-lbs.

Features

Temporary and Permanent Hold Feature
Note: This is a programmable thermostat, and will always be running a programmed schedule. However, it can be overidden with a Temporary or Permanent Hold.

Temporary Hold: With the system in Heat or Cool, anytime the SET-AT temperature is changed with the + or – buttons, the thermostat will enter a Temporary Hold. This will be indicated by “HOLD” flashing and will remain in this hold until the next programmed time period begins.

Permanent Hold: To enter a Permnent Hold, press the Hold/Run button while “HOLD” is flashing. The word “HOLD” will remain on continuously, indicating a Permanent Hold.
To Return to Running Schedule: To manually exit permanent hold and return to scheduled program, press Hold/Run button.

Tech Settings

Gas or Electric Setup

Gas: For all systems that control the fan during a call for heat, put the fan operation jumper pin to the GAS position.
Electric: Select Electric to have the thermostat control the fan during a call for heat.

Wiring Diagrams

1. Power supply
2. Factory-installed jumper. Remove only when installing on 2-transformer systems
3. Use either O or B terminals for changeover valve
4. Use a small piece of wire (not supplied) to connect W and Y terminals
5. Set fan operation setting to Electric
6. Optional 24 VAC common connection when thermostat is used in battery power mode

Technician Setup Menu 
This thermostat has a technician setup menu for easy installer configuration. To setup the thermostat for your particular application:

The Technician Setup Menu

1. To enter all other steps press hold and buttons together for 3 seconds. This 3 second delay is designed so that homeowners do not accidentally access the installer settings.
