Wiring will change when dedicated emergency heat is on (See Installer Menu #15). THERMOSTAT INSTALLATION Precautions

• Do not exceed the specication ratings.

• All wiring must conform to local and national electrical codes and ordinances.

• This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction. WARNING

Do not use on circuits exceeding specied voltage. Higher voltage will damage control and could cause shock or re hazard. Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out thermostat and could cause personal injury and/or property damage. CAUTION

To prevent electrical shock and/or equipment damage, disconnect electrical power to system, at main fuse or circuit breaker box,until installation is complete. Leveling ThermostatLeveling is for appearance only and will not aect thermostat operation. CAUTION

To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system. Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.

INSTALLER MENU To prevent changes that may aect system performance, this thermostat has an INSTALLER MENU and a USER MENU. The INSTALLER MENU provides access to every option, while the USER MENU provides access to items that will not aect system performance. To access the INSTALLER MENU press the Menu button for 8 seconds. The display will show item 05 in the table below. Use Next and Back to navigate through menu items. Press or to change a menu setting.

If the application provides a separate wire for RC and RH, clip the RC/RH jumper. This will isolate both terminals so they can be independently used. Baery Locaon Premium AA alkaline batteries are required when C-wire is not available. When C-wire is available, the batteries provide a back-up source of power (this will maintain the clock in the event of a power outage).

TEST EQUIPMENT Turn on power to the system. Fan Operation If your system does not have a G terminal connection, skip to Heating System. 1.) Press the fan button to select the On position. The blower should begin to operate. 2.) Press the fan button to select the Auto position. The blower should stop immediately. Heating System 1.) Press the System button to select the Heat position. Heat Pumps only - if the auxiliary heating system has a standing pilot, be sure to light it. 2.) Press to adjust thermostat setting to 1° above room temperature. The heating system should begin to operate and the thermostat will indicate Heat On. 3.) For heat pumps with auxiliary- Press to adjust thermostat setting to 3° above room temperature. The auxiliary heat should begin to operate and the thermostat will indicate Heat On Aux. 4.) Press to adjust thermostat setting 1° below room temperature. The heating system should stop operating and the Heat On icon will disappear. Auxiliary System ( only for heat pumps with auxiliary) 1.) Press the system button to select the Aux position. This bypasses the heat pump and runs auxiliary only heat. 2.) Press to adjust thermostat setting to 1° above room temperature. The auxiliary heating system should begin to operate and the thermostat will indicate Heat On Aux. 3.) Press to adjust thermostat setting 1° below room temperature. The auxiliary heating system should stop operating and the Heat On Aux icon will disappear. Cooling System 1.) Press the System button to select the Cool position. 2.) Press to adjust thermostat setting 1° below room temperature. The blower should come on immediately on high speed, followed by cold air circulation. The thermostat will indicate Cool On. There can be up to a 5 minute delay. (see INSTALLER MENU, item 50) 3.) Press to adjust thermostat setting to 1° above room temperature. The cooling system should stop operating and the Cool On icon will disappear.

• Away – Stores a frequently used temperature setting so that you can select it with a touch of the Away button. To set an Away temperature press temp up or temp down to the temperature you want. At the desired setting, hold the Away button for 3 seconds. When the setting is stored the set point will ash one time. You can store an Away setting for both Cool and Heat modes. (Example: Set an Away temperature to 88°F in the summer for cooling and 55°F in the winter for heating.)

• Keypad Lockout – To prevent unwanted changes, the buttons can be disabled. To turn this feature On, press and hold and the Menu button unl the icon appears (this can also be turned on in the menu). To turn O, press and hold and the Menu but- ton for 3 seconds.7 Symptom Possible Cause Corrective Action No Heat/ No Cool/ No Fan (common problem) 1.) Blown fuse or tripped circuit breaker 2.) Furnace power switch to OFF 3.) Furnace blower compartment door panel loose or not properly installed 4.) Loose connection to thermostat or system 1.) Replace fuse or reset breaker 2.) Turn switch to ON 3.) Replace door panel in proper position to engage safety interlock or door switch 4.) Tighten Connections No Heat 1.) System not set to Heat 2.) Loose connection to thermostat or system 3.) Heating System requires service or thermostat requires replacement 1.) Set thermostat to Heat. 2.) Verify thermostat and system wires are securely aached. 3.) Diagnosc: Set System to Heat and raise the setpoint above room temperature. Within ve minutes the thermostat should make a so click sound and “Heat On” should appear on display. This sound indicates the thermostat is operang properly. If the thermostat does not click, try the reset operaon listed below. If the thermostat does not click aer being reset, contact your heang and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or a service person to verify the heang system is operang correctly. (Troubleshooting continued on next page) TROUBLESHOOTING No Cool 1.) System not set to Cool 2.) Loose connection to thermostat or system 3.) Cooling System requires service or thermostat requires replacement 1.) Set thermostat to Cool. 2.) Verify thermostat and system wires are securely aached. 3.) Diagnosc: Set System to Cool and lower setpoint below room temperature. Same procedures as diagnosc for “No Heat” condion except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a ve minute delay before the thermostat clicks in Cooling if the compressor lock-out opon is selected in the installer menu. (see INSTALLER MENU, item 50) Heat, Cool or Fan Runs Constantly Possible short in wiring, thermostat, heat, cool or fan system Check each wire connection to verify they are not shorted or touching other wires. Try resetting the thermostat. If the condition persists contact your HVAC service person. Thermostat Display & Thermometer Disagree Thermostat display requires adjustment Display can be adjusted +/-5°. See User Menu item 05 Furnace (Air Conditioner) Cycles Too Fast or Slow (narrow or wide temperature swing) The location of the thermostat and/ or the size of the Heating System may be inuencing the cycle rate Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and o more frequently, but runs for a shorter time. If you would like to increase cycle time, choose SLO for slow cycle in the Installer menu. (Reference menu items 30, 32 & 35.) If an acceptable cycle rate is not achieved, contact your HVAC service person. Resetting the Thermostat or Thermostat Settings If the thermostat has good batteries, but has a blank display or does not respond to key presses, the thermostat should be reset by removing the batteries for 2 minutes. This reset will not change the menu settings or program. If the condition persists after reinstalling the batteries, replace the thermostat. To conveniently reset only the schedule and user settings back to factory defaults, press Menu and Backlight buttons at the same time and hold until the display goes blank and resets.
