Setting Thermostat Installer Options (continued)
1. Selects Residential or Commercial (BUS) profile. Determines programming
events per day. If Residential is selected, 4 events per day are available. If
Commercial is selected, 2 events per day are available. Only the 7 day
programmable mode is available for the Commercial profile.
2. Selects the programming mode, either full 7 day or 5-2 day (weekday-
weekend) programming or non-programmable. If the Commercial profile was
selected in step 1 this option is not available.
3. Selects either a 12 hour or 24 hour clock.
4. Selects preferred temperature scale of either ºF or ºC.
5. Selects Auto Changeover on or off. When off is selected, the AUTO icon
will not be displayed when selecting the system options with the system
button. When Auto Changeover mode is enabled and selected, the system
automatically switches between heating and cooling when the room
temperature meets the programmed heating or cooling set points.
6. Selects single stage conventional (11C), 2 stage conventional (22C), single
stage heat pump (11HP), 2 stage heat pump (22HP), or 3 stage heat pump
(32HP). Any change made to the system type resets Installer Options 7 through
11 to their default values dependent on system selected.
7. Selects between 1st stage gas or electric heat Fan Control. This Installer
Option is not available with a heat pump system.
8. Selects aux-stage gas or electric heat Fan Control. This Installer Option is only
available with a 2 or 3 stage heat pump system.
9. For heat pump units with an electric auxiliary stage, both the first and second
stages of heating will run when a call for second stage heat is made. For heat
pump units with a fossil fuel auxiliary stage, the compressor stage(s) will be
locked out one minute after a second stage heat call, and the second stage
will only be used.
NOTE: Can be overridden by auxiliary balance point. See
item 20 on page 10 for details.
10. Select between turning the AC power interrupt warning off or on. During a
power loss when batteries are installed, the thermostat will display an
outage warning. The system clock will continue to run, and all settings will be
maintained until the outage period is over. This Installer Option is only
available when thermostat is installed as a hardwired unit.
11. This thermostat provides cold weather compressor protection by locking out
the compressor stage (1st stage) of heating for a period of time after a power
outage greater than 60 minutes. The lockout period is one hour less than the
outage time, up to a maximum of 12 hours. During that period of time, the
auxiliary heat stage will still be available to maintain the set point tempera-
ture. The compressor lockout can be disabled by setting this option to OFF.

12. This thermostat includes an automatic compressor protection feature to
avoid potential damage to the cooling system from short cycling. This
thermostat automatically provides an adjustable delay after turning off the
cooling system output to protect the compressor. This protection is also
present in the heat mode of operation on single stage heat pump systems
to protect the compressor.
13. During the COOL mode of normal operation the fan will stay on for 60 seconds
after the cooling system has satisfied the set point temperature and has turned
off the compressor. This allows the system to provide higher efficiency during
cooling operation.The delay is selectable between 0, 30, 60 or 90 seconds.
14. The Recirculating Fan can be “locked on”, so that the only fan selections
available to the user are CIRC and ON. The Recirculating Fan Mode provides
more even temperature distribution and improves indoor air quality by
circulating air through the furnace filtration system more often. By locking the
Recirculating Fan on, the user will only have the option to run the fan all the
time (ON) or use the Recirculating Fan Feature (CIRC). If the Recirculating Fan
lock is set to off, the thermostat is put into the Recirculating Fan Mode by
pressing the FAN button until the CIRC icon is displayed. If no call for heating or
cooling occurs within the fan off cycle set in the User Options (see User Manual),
the fan will run for 12 minutes. When the fan lock is set to on, the highest
setting, 120 minutes, will run the fan least often – 9% minimum running time.
The lowest setting, 24 minutes (factory default), will run the fan most often –
33% minimum running time. The Recirculating Fan feature is available in the
COOL, OFF, HEAT, or EMER mode.
15. Enables or disables the ARM ™ feature. During ARM ™ , room temperature is
recovered gradually by turning on the heating or cooling before the end of the
set back period. In a multi-stage configuration, room temperature is recovered
gradually by using only the first stage heating or cooling until the last 20
minutes, to minimize the use of the 2nd stage heating or cooling. The set point
temperature is changed to that of the upcoming comfort program temperature.
The start time of recovery is based on the difference between the current room
temperature and the upcoming comfort program set point temperature. ARM ™
does not operate when the unit is in the temporary or permanent HOLD mode or
if the program is temporarily overridden or if emergency heat is selected for
multi-stage heat pumps. If the ARM ™ feature is disabled the thermostat will
recover the set point temperature at the programmed set point time after the
setback period ends.
