Batteries

Two “AA” alkaline batteries are included with your thermostat. Prior to use, open the battery door and remove the battery tag. We recommend replacing batteries every 2 years, for best results, use new premium brand alkalines batteries such as Duracell® or Energizer®. When the battery power remaining is approximately half, the will be displayed.

WARNING!
For California Residents: This product contains a chemical known to the state of California to cause cancer and birth defects and other reproductive harm.

CAUTION!
If the home is going to be unoccupied for an extended period (over 3 months) and is displayed, the batteries should be replaced before leaving. When less than two months of battery life remain, the setpoint temperature will change by 10 degrees (10 degrees cooler in Heat / 10 degrees warmer in Cool) to alert you to change the batteries before they fail. If the temperature change occurs, the normal setpoint can be manually reset. However, the temperature will change by 10 degrees within two days if the batteries are not replaced.

WARNING!

• Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.
• Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will damage thermostat and could cause personal injury and/or property damage.
• Thermostat installation and all components of the system shall conform to Class II (current limited) circuits per the NEC code. Failure to do so could cause a fire hazard.

Replace fuse or reset breaker. 2. Turn switch to ON. 3. Replace door panel in proper position to engage safety interlock or door switch.
No Heat	1. System Switch not set to Heat.   2. Loose connection to thermostat or system 3. Heating System requires service or thermostat requires replacement.	1. Set System Switch to Heat and raise setpoint above room temperature. 2. Verify thermostat and system wires are securely attached. 3. Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within a five minutes the thermostat should make a soft click sound. This sound usually indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed above. 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. Loose connection to thermostat or system. 3. Cooling System requires service or thermostat requires replacement	1. Set System Switch to Cool and lower setpoint below room temperature. 2. Verify thermostat and system wires are securely attached. 3. 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 configuration menu (Item 6).
Heat, Cool or Fan Runs Constantly	1. Possible short in wiring. 2. Possible short in thermostat. 3. Possible short in Heat/Cool/Fan system. 4. Fan Switch set to Fan On.
