0 to 60 minutes in increments of 3 minutes. Set 0 MIN/HR to allow AUTO control for particular periods while CLEAN is used in others. Set the fan duration to 60 MIN/HR to run the fan continuously for this period.

•Press NEXT to advance to the next period. After the four program periods of day have been programmed, pressing NEXT will advance to the following day’s MORN period.

•One period ends at the start time of the next period. The end of one period may not be any closer to the beginning of the next period than one 15-minute increment. Moving a start time too close to the next start time results in the latter time being pushed ahead too.

7.2 FILTER MONITOR

•Your thermostat will warn you that your HVAC system’s air filter should be changed by displaying FILTER in the time temperature display area, after the system’s fan has run the number of hours specified by this limit.

7.2.1 FILTER USAGE

To view the number of hours the thermostat has activated the fan since the last timer reset:

•Rotate the dial to the AIR FILTER position. The current filter usage will be shown with HRS FILTER.

•To reset the timer to 0, press UP or DOWN once. Pressing UP or DOWN again will toggle between 0 and the current value. The value in display when you exit this mode will be the value retained in memory. Leave the value at 0 to reset the timer.

•To exit the AIR FILTER mode, rotate the dial to another position.

7.2.2 FILTER LIMIT

This general rule will provide you with a good estimate of your filter’s life in hours. Assume that the fan will run at 1/3 duty cycle or 8 hours per day. Common 90-day filters are then good for 90*24/3=720 hours of use. This is the default limit value. Setting the filter counter limit to 0000 will disable the change filter indicator. Valid entries are from 0 to 2000 hours.

To set the number of hours of filter use before replacement is indicated:

•Rotate the dial to the AIR FILTER position. The current filter usage will be shown with HRS FILTER.

•Hold NEXT for 2 seconds. The Filter limit will be displayed.

•Refer to your Air Filter package to determine your filter’s recommended life. If given in days, multiply by 8 to find the recommended setting in hours of filter usage.
