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.

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.

Do not install thermostats in these 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
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 For horizontal mount put one screw on the left and one screw on the right.
  2. Vertical Mount For vertical mount put one screw on the top and one screw on the bottom.

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.
Note: To ensure a solid fit between the thermostat and the sub-base:

    1. Mount the sub-base to a flat wall
  1. Use the screws provided
  2. Drywall anchors should be flush with the wall
  3. 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.

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.
  4. Program Menu Options: Show different options during programming.
  5. Time Periods – Shows the 4 time Periods for Residential. 2 or 4 Commercial time periods Occupied/Unoccupied are shown in this text field.
  6. HOLD is displayed when the thermostat program is permanently overridden. Setpoint: Displays the user-selectable setpoint temperature
  7. System Operation Indicators: HEAT ON, COOL ON, and stages are shown when these systems are running. NOTE: The compressor delay feature is active if these icons are flashing. The compressor will not turn on until the 5-minute delay has elapsed.
  8. Clean Display: Will disable the screen for 30 seconds to allow cleaning. A press and hold of clean also will reset filter change and other reminders.
  9. Keypad Lockout Icon

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.

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.

  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 the terminal block screws.
  3. Place non-flammable insulation into the wall opening to prevent drafts. 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.

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.

Note:
In many heat pump systems with no emergency heat relay, a jumper can be installed between E and W2 to turn the 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 configured for a heat pump system. See the “heat pump” configuration step on page 17 of this manual to configure the thermostat for heat pump applications.
