•Use UP/DOWN keys to adjust the filter limit in
•Rotate the dial to RUN to finish this setting.
7.3 ENERGY USAGE
Your thermostat records the total number of hours the thermostat has activated heating and cooling with six separate timers. They measure:
•Today’s cumulative heating time.
•Yesterday’s cumulative heating time.
•Total cumulative heating time.
•Today’s cumulative cooling time.
•Yesterday’s cumulative cooling time.
•Total cumulative cooling time.
To view HEAT and COOL energy usage:
•Slide the mode switch to HEAT or COOL.
•Rotate the dial to the ENERGY USAGE position, to review today’s usage. HRS USAGE, Mode and Current Day are all shown along with the usage value.
•Press NEXT to review yesterday’s usage.
•Press NEXT again to review Total usage. The Total timer may be changed to zero by pressing UP or DOWN while Total time is displayed. To restore count, press UP or DOWN again.
•To finish review and/or reset of this mode’s energy monitor, rotate the dial to another mode. The current values will be the values retained in memory. Leave the value at 0 to reset the cumulative timer.
7.4 CALIBRATION OFFSET
Your thermostat is accurately calibrated at the factory to within ± 1˚F. An offset value up to ±5˚F may be added to the temperature value that the thermostat measures. This may allow you to match this thermostat to another. To change this offset from its default value of 0:
•Open the door on the front of the thermostat.
•Rotate the dial to SET DAY/TIME.
•Simultaneously press NEXT and HOLD. The
Temperature Offset value will flash.
•Use the UP/DOWN keys to adjust the offset value.
•Return the dial to its RUN position to accept the new value.
7.5 RESET
Your thermostat has two RESET buttons. The Software RESET in on the front of the thermostat behind the door. It is labeled RESET. HARDWARE RESET is on the rear of the circuit board.
7.5.1 HARDWARE RESET
Use this small white button labeled H_RST after changing Setup Option Jumper positions to effect the changes. The Hardware RESET turns Heat, Air and Fan off, resets the unit’s clock, and reads the Setup Option jumper positions, before initiating normal operation.
7.5.2 SOFTWARE RESET
Use this feature to make all settings and programs their default values. The Software RESET button turns Heat, Air and Fan off, resets the unit’s clock, and reads the Setup Option jumper positions. It then makes all settings and programs their default values before initiating normal operation.
N O T E: Pressing this button will overwrite your program and install the default values of all temperature programs and setup values into the unit’s nonvolatile memory. To ease reprogramming later, record your thermostat’s programs and settings in the table provided before using this button. (See Page 16)
7.6 TEMPERATURE VARIATION / SWING
•Your thermostat works by turning your heating or cooling system on and off whenever the room temperature varies a certain number of degrees from the
