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.

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.

Do not install thermostats 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

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.

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 or you can mail the thermostat to the address on the warranty section for proper disposal.

Installation Tips

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 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 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 Private Label 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 counterclockwise. 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. Indicates the current room temperature
2. Time and day of the week
3. Low Battery Indicator: Replace batteries when this indicator is shown.
   Program Time Periods: This thermostat has 4 programmable time periods per day.
4. System Operation Indicators:
   ON will display when the COOL or HEAT is on. The compressor delay feature is active if Flashing.
5. Hold is displayed when the thermostat program is permanently overridden.
6. 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 the first “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 off until the batteries are changed.

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 non-flammable 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.

Terminal Designations

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

Wiring Tips

• RH & RC Terminals
  For single transformer systems, leave the jumper wire in place between RH and RC. Remove the jumper wire for the two transformer systems.
• Heat Pump Systems (With NO AUX or Emergency Heat)
  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 overridden with a Temporary or Permanent Hold.
Temporary Hold: At this time if you do nothing, the temperature will remain at this setpoint temporarily for 4 hours.
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: Press the RUN SCHED button on the left of your screen to exit either temporary or permanent hold.

Tech Settings

Gas or Electric Setup

Fan Operation Switch
Gas: For systems that control the fan during a call for heat, put the fan operation switch to the GAS position.
Electric: For systems that do not control the fan during a call for heat, put the fan operation switch the ELECTRIC position.

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 the 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 the thermostat is used in battery power mode

Tech Settings
