A trained, experienced
the 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.

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.

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.

Do not install thermostats in locations:

• Close to hot or cold air ducts
• That is 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:
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 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.

Thermostat Quick Reference

1. LCD Display
2. Glow in the dark light button
3. Fan Switch
4. System Switch
5. Easy change battery door
6. Temperature Setpoint Buttons
7. 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. Button Options
5. Program Time Periods: This thermostat has 4 programmable time periods per day.
6. System Operation Indicators: The COOL ON, HEAT ON, or icon will display when the COOL, HEAT, or  (fan) is on.
   Note: The Compressor delay feature is active if these are flashing.
7. the hold is displayed when the thermostat program is permanently overridden.
8. 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 and 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 the wall opening to prevent drafts.

Terminal Designations

• O Heat pump changeover valve energized in cooling
• 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
• B The common wire from the secondary side of the cooling system transformer

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.

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.

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 sub-base correctly or cause system operation issues. Max Torque = 6in-lbs.

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.

Features

Temporary and Permanent Hold Feature (If using programming)
When cool or heat is turned on, the thermostat will display HOLD and RUN SCHED on the left of your screen when you press the or button.
Temporary Hold: At this time if you do nothing, the temperature will remain at this setpoint temporarily until the next time period.
Permanent Hold: If you press the HOLD key on the left of your screen, you will see HOLD appear below the setpoint temperature in the display. The thermostat will now permanently stay at this setpoint and can be adjusted using the or keys. To Return to Running Schedule: Press the RUN SCHED button on the left of your screen to exit either temporary or permanent hold.

Filter Change Reminder
If your installing contractor has configured the thermostat to remind you when the air filter needs to be changed, you will see FILT in the display when your air filter needs to be changed.
Resetting the filter change reminder: When the FILT reminder is displayed, you should change your air filter and reset the reminder by holding down the second button from the top left side of the thermostat for 3 seconds.

Resetting the filter change reminder: When the FILT reminder is displayed, you should change your air filter and reset the reminder by holding down the second button from the top left side of the thermostat for 3 seconds.

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.
