This thermostat is configured from the factory to operate a heat/ cool, fossil fuel (gas, oil, etc.), forced air system. It is configured correctly for any system that DOES NOT require the thermostat to energize the fan on a call for heat. If your system is an electric heat or heat-pump system that REQUIRES the thermostat to turn on the fan on a call for heat, locate the ELECTRIC/GAS switch on the back of the thermostat (see fig. 1) and switch it to the ELECTRIC position. This will allow the thermostat to energize the fan immediately on a call for heat. If you are unsure if the heating/cooling system requires the thermostat to control the fan, contact a qualified heating and air conditioning service person.
Figure 1. Thermostat Base
2 "AA" alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage. You must remove the battery tag to engage the batteries.
If "BATT" is displayed, the batteries are low and should be replaced. For best results, replace all batteries with new premium brand alkaline batteries such as Duracell® or Energizer®. To replace batteries, install the batteries along the top of the base (see Fig. 1). The batteries must be installed with the positive (+) end to the left.
This thermostat is set to operate properly with a forced-air heating system. If you have a hydronic heating system (a system that heats with hot water or steam), you must set the thermostat to operate properly with your system. Change the second option in the configuration menu to SL (see CONFIGURATION MENU).
If at any time during testing your system does not operate properly, contact a qualified service person.
Turn on power to the system.

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.
This section will help you plan your thermostat's program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program.
Planning Your Program
Look at the factory preprogrammed times and temperatures shown in the sample schedule. If this program will suit your needs, simply press the RUN button to begin running the factory preset program.
If you want to change the preprogrammed times and temperatures, follow these steps.
Determine the time periods and temperatures for your weekday and weekend programs. You must program four periods for both the weekday and weekend program. However, you may use the same heating and cooling temperatures for consecutive time periods. You can choose start times, heating temperatures, and cooling temperatures independently for both weekday and weekend programs (for example, you may select 5:00 AM and 70° as the weekday 1st period heating start time and temperature, and also choose 7:00 AM and 76° as the weekday 1st period cooling start time and temperature).
Use the following table to plan your program time periods and the temperatures you want during each period. Fill in the complete table to have a record of your programs.
Entering Your Program
Follow these steps to enter the heating and cooling programs you have selected.

If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by pressing , and TIME at the same time. This also resets the factory defaults to the configuration menu and program. If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.
Batteries
For optimum performance, we recommend replacing batteries once a year with fresh "AA" alkaline batteries.
Symptom | Possible Cause | Corrective Action |
No Heat/No Cool/No Fan
|
1. Blown fuse or tripped circuit breaker. 2. Furnace power switch to OFF. 3. Furnace blower compartment door or panel loose or not properly installed. |
Replace fuse or reset breaker. Turn switch to ON. Replace door panel in proper position to engage safety interlock or door switch. |
No Heat |
1. Pilot light not lit. 2. SYSTEM Switch not set to HEAT. 3. Loose connection to thermostat or system. 4. Furnace Lock-Out Condition. Heat may also be intermittent. 5. Heating System requires service or thermostat requires replacement. |
Re-light pilot. Set SYSTEM Switch to Heat and raise setpoint above room temperature. Verify thermostat and system wires are securely attached. Many furnaces have safety devices that shut the system down when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance. Diagonistic: Set SYSTEM Switch to HEAT and raise the setpoint above room temperature. Within a few seconds 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. |
Set SYSTEM Switch to COOL and lower setpoint below room temperature. Verify thermostat and system wires are securely attached. Same procedure 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. FAN Switch set to Fan ON. 2. Possible short in wiring. 3. Possible short in thermostat. 4. Possible short in Heat/Cool/Fan system. |
Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under terminal screws. Try resetting the thermostat. If the condition persists the manufacturer of your system or service person can instruct you on how to test the Heat/Cool system for correct operation. If the system operates correctly, replace the thermostat. |
Furnace Cycles Too Fast or Too Slow(narrow or wide temperature swing) |
1. The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate. | Item 2 in the Configuration Menu is the adjustment that controls the cycle rate. If an acceptable cycle rate is not achieved using the FA (Fast) or SL (Slow) adjustment contact a local service person for additional suggestions. |
Cooling Cycles Too Fast or Too Slow(narrow or wide temperature swing) |
1. The location of the thermostat and/or the size of the Cooling System may be influencing the cycle rate. | The cycle rate for cooling is fixed and can not be adjusted. Contact a local service person for suggestions. |
Thermostat Setting and Thermometer Disagree |
1. Thermostat thermometer setting requires adjustment. | The thermometer can be adjusted +/- 4 degrees as listed in item 7 of the Configuration Menu. No other adjustment is possible. |
Clock Loses or Gains Time |
1. Loss of power to thermostat and low batteries. | The thermostat will maintain its program in memory even with no power/no batteries but the clock time will be incorrect when power is restored. See No Heat/No Cool/No Fan (common problems) above for items to check in the system. |
Heat or Cool Starts Early |
1. EMR activated | See Configuration Menu (Item 4). |
Thermostat Does Not Follow Program |
1. AM or PM set incorrectly in program. 2. AM or PM set incorrectly on the clock. 3. Voltage spike or static discharge. |
Check current clock and program settings including the AM or PM designations for each time period. If a voltage spike or static discharge occurs use the Reset Operation listed above. |
Blank Display and/or Keypad Not Responding |
1. Loss of power and dead batteries. 2. Voltage Spike or Static Discharge. |
