Thermostat Application Guide

Power Type

• Battery Power
• Hardwire (Common Wire)
• Hardwire (Common Wire) with Battery
• Backup

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

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.

Outdoor temperature sensors, Indoor temperature sensors, and Slab sensor wiring diagrams are located in the sensor manuals. See page 18 in tech setup.

Thermostat Quick Reference

1. LCD Display
2. Glow in the dark light button
3. Fan Key
4. System Key
5. Setpoint buttons
6. Menu button

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.

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. Optional 24 VAC common connection when the thermostat is used in battery power mode

In many systems with no emergency heat relay a jumper can be installed between W/E and W2.

Technician Setup Menu

This thermostat has a technician setup menu for easy installer configuration. To set up the thermostat for your particular application:

1. Press the Menu button.
2. Press and hold the TECHNICIAN SETUP button for 3 seconds. This 3-second delay is designed so that homeowners do not access dentally access the installer settings.

Swing Setting Tip
The second stage will turn on at 2x the swing set. The second stage will turn off when 1x the swing is reached. For example, if the swing set is .5 degrees for heating and the thermostat is set at 70ËšF, the first stage will turn on at approximately 69.5. The second stage will turn on at 69ËšF. The second stage will turn off at 69.5ËšF and the first will turn off at 70.5ËšF. If the third stage is used, it will turn on at 68.5ËšF and turn off at approximately 69ËšF.

Contractor Call Number Note
If the contractor call number is selected ON, the phone number entered will show in the display if there has been a continuous call for heating or cooling for 24 hours or if the light button is held down for 3 seconds. To remove the phone number from the display, hold the light button down for 3 seconds.

A Note about IAQ Mode
This programmable/selectable mode will operate the fan 1-4 cycles per hour, 1-45 minutes per cycle. Once programmed in tech setup, to enable this mode select “IAQ” with the fan key. Disable this mode by selecting “ON” or “AUTO” with the fan key.
Reminders: Once a reminder has been turned on and set, the elapsed time can be checked by navigating to its tech setup step. The elapsed time will then appear in the text field. It can also be reset at that time by holding down the Clean key button for 3 seconds. Resetting an expired reminder can be done without entering tech setup, by holding down the Clean key button for 3 seconds from the home screen.
