TOOLS YOU MAY NEED: Screwdrivers, wire stripper / cutter, and possibly a drill with assorted bits (new installations only). REMOVAL OF OLD THERMOSTAT: 1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on until all work is completed. 2. Remove the front portion of your old thermostat to expose the wiring connections. 3. Write down the letters printed near each wire terminal that is used, and also the color of each wire that is connected to it.

WIRING TERMINAL CONNECTIONS: 1. When attaching the wires to the thermostat, please ensure that the bare wire ends are held ALL the way into the terminal block while the screw is being tightened. 2. Securely tighten all of the electrical terminal screws, including any unused ones. Be careful not to over tighten the screws, they only need to be snug. ** Complete heating and/or cooling system wiring can be found in the WIRE IDENTIFICATION AND WIRING SCHEMATICS section of this instruction sheet.

OPERATING INSTRUCTIONS: HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control your heating system, and COOL to control your cooling system. The OFF position will disable both the heating and cooling units. AUTO / ON, FAN SWITCH: When this switch is in AUTO, the blower fan (if present in your system) will automatically cycle on and off by itself when heating or cooling is running.

ADVANCED FEATURES: TEMPERATURE SWING: The amount of temperature variation between load-on and load-off is changed by adjusting the swing setting. The default value for this thermostat is #4, and the adjustment range is from #1 to #9. A smaller swing number makes the temperature control more precise and constant, and increases the number of cycles per hour. A larger swing number will produce a greater variation between load-on and load-off events, and decreases the number of cycles per hour.
