THERMOSTAT INSTALLATION

WIRING Refer to equipment manufacturer’s instructions for specific system wiring information. After wiring, see INSTALLER MENU for proper thermostat configuration. The wiring table shown is for typical systems and describes the thermostat terminal functions.

Damper Systems
Y| Heat and Cool Mode 1st Stage Compressor
G| Fan Relay
E| Auxiliary only Heat Mode (Emergency Heat)
C| Common wire for 24V (optional with batteries)
L| Heat Pump malfunction / Diagnostic terminal (input signal requires common)
W2| Heat Mode – 2nd stage

*Cut W2/E jumper when separate heat sources are used for W2 and E. IMPORTANT: For Dual Fuel Heat Pump applications, be sure to turn on the Duel Fuel Logic option (found in the Installer’s Menu)

Precautions

• Do not exceed the specification 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 specified voltage. Higher voltage will damage control and could cause shock or fire hazards. Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will burn out the thermostat and could cause personal injury and/or property damage. CAUTION! To prevent electrical shock and/or equipment damage, disconnect electrical power to the system, at the main fuse or circuit breaker box, until installation is complete. Battery Location Premium AA alkaline batteries are required when C-wire is not available. When C-wire is available, the batteries provide a backup source of power (this will maintain the clock in the event of a power outage).

1. W2/E Jumper Wire This thermostat electrically connects the W2 and E terminals so that you do not need to do this with a jumper wire. If your system has separate W2 and E wires, clip the W2/E jumper located on the back of the thermostat. This will isolate both terminals so they can be used independently.
2. O/B Terminal Switch The O/B switch on this thermostat is factory set to the O position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in Cool. If the heat pump is installed requires a B terminal to energize the changeover relay in Heat, the O/B switch must be moved to the B position.

INSTALLER MENU

To prevent changes that may affect system performance, this thermostat has an INSTALLER’S MENU and a USER MENU. The INSTALLER’S MENU provides access to every option, while the USER MENU provides access to items that will not affect system performance. To access the INSTALLER’S MENU press the Menu button for 8 seconds. The display will show item 30 in the table below. Use Next and Back to navigate through menu items. Press or to change a menu setting.

TROUBLESHOOTING

breaker 2.) Furnace power switch to OFF 3.) Furnace blower compartment door panel loose or not properly installed 4.) Lose connection to thermostat or system| 1.) Replace fuse or reset the breaker 2.) Turn the switch to ON 3.) Replace the door panel in the proper position to engage the safety interlock or door switch 4.) Tighten Connections
No Heat| 1.) System Switch not set to Heat 2.) Lose connection to thermostat or system 3.) Heating System requires service or thermostat requires replacement| Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within five minutes the thermostat should make a soft click sound and “Heat On” should appear on display. This sound indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed below. If the thermostat does not click after being reset, contact your heating 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 heating system is operating correctly.
No Cool| 1.) System Switch not set to Cool 2.) Lose connection to the thermostat or system 3.) Cooling System requires service or thermostat requires replacement| Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Cool and lower setpoint below room temperature. Same procedures as diagnostic for “No Heat” condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five-minute delay before the thermostat clicks in Cooling if the compressor lock-out option 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| The display can be adjusted +/-5°. See User Menu item 04
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 influencing the cycle rate| Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off 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 & 35) If an acceptable cycle rate is not achieved, contact your HVAC service person.
“Call for Service” icon appears on the display| 1.) Heating system is not able to heat the space to within 10 degrees of the setpoint within 2 hours 2.) Cooling system is not able to cool the space to within 10 degrees of the setpoint within 2 hours 3.) If “–” is displayed for the Room Temperature, a replacement thermostat is needed 4.) None of the buttons operate on the thermostat 5.) If “Call for Service” is flashing, compressor self-diagnostic is detecting an issue with the outdoor unit| 1.) See corrective action for “No Heat” 2.) See corrective action for “No Cool” 3.) Replace the thermostat 4.) Make sure keypad lockout is not turned on (denoted by the icon) 5.) Contact a service person to verify the equipment is operating correctly

Resetting the Thermostat or Thermostat Settings If the thermostat has good batteries, but has a blank display or does not respond to keypresses, 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 the Menu and Backlight buttons at the same time and hold until the display goes blank and resets.
