Installation

Replacing Existing Thermostat

Most thermostats have three parts:

• The cover, which may snap or hinge over the existing thermostat.
• The electronics or body, which controls the existing system.
• The sub-base, where the wires attach through the wall to the existing system.

1. Always turn off power to the air conditioning and heating system prior to removing existing thermostat.
2. Carefully remove the cover and electronics body from the old thermostat sub-base. Depending on the brand, these parts may pull off or need to be unscrewed. The old sub-base should remain wired and on the wall until steps 4 and 5.
3. Label every old wire with the letter of the connection to which the wire is attached. Example letters are R, M, and Y etc. Depending on the brand of the old thermostat, your letters may be different.
4. After labeling the old wires, loosen each connection and remove them from old sub-base. Secure the wires to prevent them from slipping into the hole in the wall.
5. Remove the old sub-base from the wall, again being careful that the wires do not slip into the hole in the wall.
6. Use the chart below to determine the new thermostat connections. As an example, if the old thermostat had a G or F connection, it goes to G on the new thermostat. Using a pencil and the chart below, circle the letter of each wire removed from the old thermostat.

NOTE: This thermostat is designed for use with 24 Volt AC low voltage single stage gas, oil or electric heating or cooling systems, including single stage heat pumps. This thermostat can also be used on 250mv to 750mv millivolt heating only systems. Do not use this thermostat on applications with voltages above 30 Volts AC.

Installing Your New Thermostat

NOTE: When installing this thermostat in a new location, following a few simple guidelines and the applicable building codes will give the best results. Install the thermostat in a location that provides good airflow by avoiding areas behind doors, near corners, air vents, direct sunlight or heat generating devices. The wiring must conform to all building codes and ordinances as required by local and national code authorities having jurisdiction for this installation.

1. Always turn off the power to the air conditioning and heating system prior to installing this thermostat.
2. Locate the release latch on the bottom (not the back) of the thermostat. Press the release latch in and separate the body from the sub-base of the thermostat.
3. Set the thermostat electronics and cover down on a clean surface. Place the sub-base on the wall in the desired location.
4. Using the slotted mounting holes in the sub-base, mark the placement of the mounting holes through the slots and onto the wall. Insure the wires come out of the wall into the center hole of the sub-base.
5. After verifying the drill will not damage items in the wall, use a 3/16 drill to create the mounting holes. Gently tap the supplied plastic anchors into the holes in the wall.
6. Place the thermostat sub-base against the wall in the desired location. Ensure the thermostat is level, the wires are inserted in the opening, and the mounting holes are aligned with the slots on the sub-base.
7. Fasten sub-base to wall using the supplied screws into the plastic wall anchors.
8. Connect wires to the quick wiring terminal blocks. Use the wiring diagram chart to insure the old and new connections are correct.
9. To prevent electrical shorts and potential damage to the thermostat, make sure all wire connections are secure and not touching each other.

To prevent accidental or undesired adjustment of the thermostat, the Keypad Lockout feature disables the operation of the keypad except for the backlight key. In order to lock the keypad, press and hold both the and buttons together at the same time for 5 seconds. The LOCK segment in the display will flash once per second, and then appear continuously in the display. The keypad is now locked. To unlock the keypad, press and hold the and buttons together at the same time for 1 second. The LOCK segment will disappear and the keypad will become unlocked.

Adaptive Recovery Mode (ARM™)

In order to maximize comfort and energy efficiency, this thermostat is equipped with an Adaptive Recovery Mode (ARM™). This feature minimizes the amount of time required by heating or cooling system to reach the new set point, after a setback period is completed, and assures your desired temperature is achieved at your set program times.
This feature activates when recovering room temperature from setback programs to comfort programs, so it will only take place when the current (heating) program set point temperature is lower than the upcoming program set point temperature, or the current (cooling) program set point temperature is higher than the upcoming program set point temperature.
During ARM™, room temperature is recovered gradually by turning on the heating or cooling before the end of the setback period. The set point temperature is changed to that of the upcoming comfort program temperature. The start time of recovery is based on the difference between the current room temperature and the upcoming comfort program set point temperature. The recovery to the upcoming set point starts 10 to 15 minutes before the upcoming set point time for each degree of temperature change required, up to a maximum of 2 hours in the HEAT mode, 3 hours in the COOL mode.
ARM™ does not operate when the unit is in HOLD mode, or if the program is temporarily overridden.

Circulating Fan Mode–Fan Operation

AUTO: Fan operates as required by heating or cooling system.
: When heating or cooling is not active, fan will run as needed to ensure a 35% minimum run time.
ON: Fan will run at all times.

Compressor Protection

This thermostat includes an automatic compressor protection feature to avoid potential damage to the cooling system from short cycling. This thermostat automatically provides a 5-minute delay after turning off the cooling system output to protect the compressor. This protection is also present in the heat mode of operation on single stage heat pump systems to protect the compressor.

NOTE: The installer can reset the thermostat and bypass the compressor protection features by pressing the RESET button. This will erase all entered programs, current time of day, day of week and other user settings and should only be used during installation for testing purposes or to reset a thermostat to regain normal operation. This will return all thermostat settings to their default values.

Low Battery Detection

This thermostat requires two (2) new, properly installed "AA" Alkaline batteries to maintain the system clock and to provide proper thermostat power when 24 volt AC power fails or is not connected to the thermostat. When the batteries start to become too weak to provide proper operation, the thermostat will begin to display a low battery indicator.

The low battery indicator is provided to inform the user when the batteries require immediate attention. We recommend replacing the batteries as soon as the low battery indicator appears. If the batteries are not replaced after the low battery indicator first appears, the thermostat may not provide proper heating or cooling system operation.

Even if the low battery indicator does not appear, the batteries should be replaced at least once a year, or if you plan on leaving the premises for over a month.
This thermostat can be powered from 24 volts AC or battery power. To determine if 24 volt AC power is connected to the thermostat, refer to the installation and wiring diagram section. If you cannot determine how this thermostat is powered, call a professional service technician to determine the type of installation and the proper operation of your system.

Resetting the Thermostat

The Reset feature allows the user to completely reset the thermostat to register new manual switch settings. To erase all entered programs, current time of day, day of week and other user settings, gently press the RESET button using a paper clip or a small pencil tip. This will return all thermostat settings to their default values and register all new manual switch settings for proper operation.

Non-Volatile Memory

In the event of a power failure, the Non-Volatile Memory feature allows all settings to be recovered, eliminating the need to reset temperature and differential settings. When AC power is restored after an outage, all settings are retrieved from memory and reinstated.

Status Indicators

HEAT: This will turn on whenever the system switch is in the HEAT mode. "HEAT" will flash when the heating system is running.

COOL: This will turn on whenever the system switch is in the cool mode. "COOL" will flash when the cooling system is running.
