INSTALLER/CONFIGURATION MENU
reached, trying to raise or lower the setpoint past the limit
will cause “L” to be displayed in the times digits for about 6
seconds. This feature not available on earlier models.
16) Program Options: Configured for 7 day or 5/1/1 day pro-
gramming or non-programmable mode. The default set-
ting is P7, indicating 7 day programming. The programs
per week can be changed to P3 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.
17 & 18) Select Automatic Schedule – With just one touch
of the AUTO SCHEDULE button this feature allows
you to program a desired comfort temperature into all
the program periods along with a 6° set back for night
periods 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.
19 & 20) 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.
21) 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.
22) Select Daylight Saving Time Calculation – This feature
will allow the thermostat to calculate the DST automati-
cally and apply it to the Real Time Clock display. Default
On. Use or buttons to select the feature OFF.
23) 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 but-
ton to clear the display and restart the time to the next
filter change.
24) 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.

the thermostat to automatically select heating or cooling
depending on the indoor temperature and the selected heat
and cool temperatures. When using
AUTO, be sure to set the
Cooling temperatures more than 1° Fahrenheit higher than
the heating temperature.
