Setting Your Energy Saving Programs
Tips Before Starting
5.4.1
• It is important for you to set the current time of day (note AM/PM indicator in display), and the current day of week correctly to avoid problems with program execution. This must be done prior to entering any program settings.
• Both the heating and cooling programs use the same setpoint times, but allow different setpoint temperatures.
• This thermostat is pre-programmed with setpoint times and temperatures recommended by the U.S. Environmental Protection Agency & the U.S. Department of Energy in their Energy Star program. These settings provide efficient energy savings during normal heating and cooling modes of operation. Review these time and temperature settings prior to establishing your personal program settings to maximize your savings, & minimize programming requirements.
• Make sure you place the system switch in the HEAT or COOL modes of operation as appropriate. The thermostat will not allow you to enter a program in the OFF position. The EMER (Emergency Heat) mode will be considered the same as the HEAT mode of operation for programming purposes. We do not recommend programming in the EMER mode.
• When you place the system switch in the COOL, OFF, HEAT or EMER, modes of operation, the appropriate indicator will also appear in the LCD display when the system is running.
Whole Week –
allows you to program all seven days (M, TU,W, TH, F, SA, SU will show in display) at the same time. Then you can use individual day programming to fine tune your program for the few setpoint times or temperatures that you may wish to change.
Weekday –
allows you to program all the weekdays (M, TU,W, TH, F will show in display) at the same time. Then go to Weekend group mode to finish programming your weekend setpoint times and temperatures. Individual day programming can be used to fine tune your settings to match your daily needs.
Weekend –
allows you to program the weekend days (SA, SU will show in the display) at the same time. Again, individual day programming can be used to change specific setpoint times or temperatures.
5.4.2
Using Quick Program Groups or Individual Day Programming
Once you enter program mode, you can select the Quick Program Group or Individual Day Programs as you desire.
See
Entering Your Program
section
You can select one of three Quick Program Groups or Individual Day programming to allow you to change the daily setpoint times and temperatures to meet your individual schedule needs. The Quick Program Groups can be used to set the main portion of your schedule, allowing you to later modify specific days of the week as required using the Individual Day programming capabilities.

Multi-Colored LED Status Indicators
The three multi- colored LED Status Indicators located on the front of your thermostat above the display will notify you of key system information.
AUX (Green): This will turn on when the auxiliary second stage of heating is active. The
auxiliary stage of heating is usually the least economical stage of heat.
CHECK (Red): Indicator will activate when a malfunction occurs in the heat pump system.
When the light is active, call a professional service technician to verify system performance and switch the system to Emergency Heat Mode if required to maintain room temperature.
EMER(Red): This indicator will light when you select Emergency Heat Mode of operation using
the system selector switch. When you select Emergency Heat Mode, the heat pump stage of heat is turned off and the emergency (auxiliary) stage of heating is used to maintain the setpoint temperature.

Verify your program setpoint time entries. The heating and cooling programs utilize the same setpoint times,but have individual setpoint temperatures for the MORN, DAY, EVE and NIGHT setpoints. See Setting Your Energy Saving Program section of this manual.
Thermostat program has been temporarily overridden and program indicator is flashing in the display. Wait till next setpoint and the temporary override will expire or change setpoint temperature to desired comfort level.
Thermostat program is in Permanent Hold (Vacation) Mode and HOLD and TEMP is showing in display. Press HOLD button to release permanent hold and return the thermostat to normal program operation.
Thermostat turns heating or cooling system on too often or not often enough.
Increase or decrease first stage temperature differential setting as appropriate to provide the desired performance level. See
Setting Temperature Differential and Residual Cooling Fan Feature section of this manual.
SYMPTOM POTENTIAL SOLUTION
Thermostat does not turn on heating or cooling system.
Check to see if OFF is shown in display. This indicates that the system is turned off at the thermostat. Move the system selector switch to the HEAT or COOL position. After the compressor short cycle protection 5-minute period expires the system should start within a minutes time.
Compressor protection features may be in effect due to compressor short cycle conditions. See Compressor Protection section for full explanation of this feature.
Heat Pump may be malfunctioning. Review the CHECK status indicator light to see if it is lit. If the CHECK status indicator light is lit, call a professional service technician to confirm heat pump operation and provide necessary service. If heating is required you can slide the system switch to EMER setting which will start the Emergency Heat source to provide heating until the heat pump can be serviced.
Thermostat turns on heating instead of cooling.
Check thermostat wiring to make sure that the heating and cooling stages are connected to the correct terminals on the wiring terminal block. See Installation and Wiring Diagrams sections of this manual.

SYMPTOM POTENTIAL SOLUTION
Thermostat turns on second (auxiliary) stage of heating or cooling too quickly or not quickly enough.
Increase or decrease second (auxiliary) stage temperature differential setting as appropriate to provide the desired performance level. See Setting Temperature Differential and Residual Cooling Fan Feature section of this manual.
Low Battery Indicator is shown in thermostat display.
Replace back-up batteries as soon as possible. See Low Battery Detection and Replacement section of this manual.
OFF is shown in thermostat display and heating or cooling system will not start.
This indicates that the system is turned off at the thermostat. Move the system selector switch to the HEAT or COOL position. After the compressor short cycle protection 5-minute period expires the system should start within several seconds.
Thermostat display is blank.
It is possible that AC power is not present at the thermostat and the back-up batteries are fully discharged.Check fuse, circuit breaker and thermostat wiring as appropriate to verify AC power is available. Replace back-up batteries before re-programming thermostat to make sure you have back-up power. See Low
Battery Detection and Replacement and SettingYour Energy Saving Program sections of this manual.
If AC Power is present, call a professional service technician to verify thermostat and system performance.
Thermostat will not allow me to program a setpoint temperature higher than 90˚ F (32˚ C).
This is above the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).
HI is shown in the thermostat display where the room temperature is normally displayed.
The temperature sensed by the thermostat is higher than the 99˚ F (37˚ C) upper limit of the thermostats display range. The display will return to normal after the sensed temperature lowers within the 40˚ to 99˚ F (5˚ to 37˚ C) display range. Turn on the cooling system or use other methods to lower the temperature accordingly.
This condition could occur from the system being turned off during an exceptionally warm period or upon installation when the thermostat has been stored for a long period of time in a warm vehicle or location prior to being installed. The thermostat is equipped with a mechanical high temperature safety switch that will turn off the system should the temperature exceed 99˚ F (37˚ C).

SYMPTOM
POTENTIAL SOLUTION
Thermostat will not allow me to program a setpoint temperature lower than 45˚ F (7˚ C).
This is below the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).
Fan continues to run all the time whether the system is on or off.
Check that the fan control switch is in the AUTO position. This will allow the fan to run only when the heating or cooling system is turned on and running.
Check thermostat wiring to make sure that the fan control wiring is connected to the correct terminals on the wiring terminal block. See Installation and Wiring Diagrams sections of this manual.
Fan continues to run in cooling mode when the system has turned off.
The Residual Cooling Fan Control Feature can allow up to a 90 second fan delay after cooling system shutdown for energy efficiency gains. The default setting is 60 seconds. This can be changed to disable this feature or shorten the time period if desired. See Setting Residual Cooling Fan Feature section of this manual.
The room is too warm or too cold.
See Review Set Temperature section of this manual to verify the current setpoint and make any modifications that are necessary.
LO is shown in the thermostat display where the room temperature is normally displayed.
The temperature sensed by the thermostat is lower than the 40˚ F (5˚ C) lower limit of the thermostats display range. The display will return to normal after the sensed temperature rises within the 40˚ to 99˚ F (5˚ to 37˚ C) display range. If the temperature in the controlled space seems to be normal, wait for the thermostat to acclimate to the correct room temperature. If the room seems to be colder than usual, turn on the heating system to raise the temperature as needed for comfort within the room.
This condition could occur from the system being turned off during a cold weather period or upon installation when the thermostat has been stored for a long period of time in a cold vehicle or location prior to being installed. The thermostat should be allowed to warm up prior to installation to allow proper heating control once installed.
