INSTALLER/CONFIGURATION MENU

The programs per week can be changed to P2 or P0 by

pressing the or keys. A selection of 0 Days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped.

19 & 20) Select Automatic Schedule – 1F85 only, with just one touch of the Auto Schedule key this feature allows

you to program a desired comfort temperature into all the

program periods along with a 6° set back for night peri- ods of both Heat and Cool programs. Factory default is “On” for both. When Heat AS On and Cool AS On are activated while in Heat or Cool mode, select desired setpoint temperature and press Auto Schedule. This value will be copied into all the morning, day and evening program periods. The night program periods will have a 6°F set back.

21 & 22) Select Fast Second Stage ON or OFF – Heat pump or Multi-stage only, in the run mode, with the fast Heat feature enabled (FA Heat On), if the Heat setpoint temperature is manually raised by 3°F (2°C) or more

above the actual temperature using the second stage will energize immediately. With FA OFF, second stage will not energize until the setpoint temperature is 1°F or more above actual temperature for more than ten minutes. The Fast Cool feature (FA Cool) provides the same controls when the setpoint temperature is lowered.

23)Comfort Alert with Active Protection – Turn this feature ON to enable active protection. This allows the thermostat to identify fault codes sent by the Comfort Alert module when compressor damage is possible and react to those codes by turning the compressor off. Fault codes from the Comfort Alert module will flash on the thermostat. (Refer to Comfort Alert Yellow Alert Codes

in Troubleshooting section.) If a Comfort Alert module is not connected, or to disable active protection, turn this feature OFF. If a Comfort Alert module is connected and this feature is turned OFF, the thermostat will still receive and flash the fault codes from the Comfort Alert module, but the active protection will not be enabled to protect the compressor.

24)Select Daylight Saving Time Calculation – 1F85 only, this feature will allow the thermostat to calculate the DST automatically and apply it to the Real Time Clock display.

Default On. Use or touch keys to select the feature OFF.

25 & 26) Select Filter Replacement Reminder and Set Run Time – Select the “Change Filter” reminder On or OFF. If selected On, press MENU to select the time period from 25 to 1975 hours in 25 hours increments. In a typical system, 200 hours (default) of run time is approximately 30 days. After the selected time of blower operation, the thermostat will display “Change Filter” as a reminder to change or clean your air filter. When “Change Filter” is displayed, press MENU or RUN SCHED button to clear the display and restart the time to the next filter change.

27)Select Reversing Valve Output – The O/B option is factory set at “O” position. This will accommodate the majority of heat pump applications, which require the

changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in HEAT, the O/B option should be set at “B” position.
