A second press subtracts one hour from the original time, and a third press returns the unit to the original time. After one minute with no new DST button presses, the sequence is reset staring with the current displayed time.

4.3.5 AIR FILTER

This unit incorporates a timer, which records the number of hours the thermostat has activated the fan. This timer is intended to indicate when your HVAC systems filter should be cleaned or replaced.

●Refer to the User setup menu to set the number of hours the timer will use to indicate that changing the filter is recommended.

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

4.3.6 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

●Today’s cumulative cooling time

●Yesterdays cumulative heating time

●Yesterdays cumulative cooling time

●Total cumulative heating time

●Total cumulative cooling time

To view this set of timer values:

●Rotate the dial to the ENERGY USAGE position. Timer values will repeatedly display the above sequence.

●The cumulative timers may be reset by pressing the UP or Down arrow key once. Pressing an arrow key again will toggle between 00:00 and the current value. Pressing the UP or Down arrow key also stops the scroll- ing.

●Press NEXT to resume scrolling.

●When you rotate the dial to another mode, the current values will be the values retained in memory. Leave the value at 00:00 to reset the cumulative timers.

4.3.7 FUTURE OUTDOOR SENSOR

An optional outdoor sensor may be installed to enable the thermostat to display the temperature outside your home. This sensor may also be used to instruct the unit to switch from a heat pump to another source of heat. Once installed the outdoor temperature will alternate with the time in the display. To install an outdoor sensor refer to the Installation Section of this manual. To enable an outdoor sensor or change heat pump settings refer to the Installers Setup Section of this manual.

4.3.8 FUTURE REMOTE INDOOR SENSORS

Up to three optional indoor sensors may be installed. The temperature measurements of all active indoor sensors will be averaged and used in temperature control. With remote indoor sensors functioning, the units’ internal temperature sensor may be enabled or disabled to allow the thermostat to be mounted in locations that would otherwise be non-ideal.

To install indoor temperature sensors refer to the Installation Section of this manual. To enable or disable the units internal sensor or other remote indoor tempera- ture sensors refer to the Installers Setup Section of this manual.

4.3.9 RESET
