4.2.4 TEMPERATURE DISPLAY FORMAT (F/C DISPLAY)

Temperature may be displayed in Fahrenheit or Celsius
with this option.

4.2.5 CLOCK FORMAT

The time shown on the thermostats clock may be dis-
played in 12 or 24 hour format. Set this option to your
preference.

4.2.6 CALIBRATION OFFSET

Your thermostat is accurately calibrated at the factory to
within ±1°F An offset value up to ±5°F may be added to
the temperature value that the thermostat measures. This
may allow you to match this thermostat to another.

4.2.7 MAXIMUM HEAT SETTING

The temperature that this option is set to will be the high-
est HEAT SET temperature available in run mode or while
programming the thermostat.

4.2.8 MINIMUM COOL SETTING

The temperature that this option is set to will be the low-
est COOL SET temperature available in run mode or while
programming the thermostat.

4.2.9 SMART RECOVERY

Your thermostats Smart Recovery allows your HVAC sys-
tem to attempt to recover from a setback period and
reach your desired comfort temperature set point by the
beginning of your programmed comfort period. This
option allows you to choose whether to use Smart
Recovery.
If enabled, Smart Recovery will initiate if:
Recovery is valid only from a night setback to morning
●
comfort or day setback to evening comfort period.
In Heat mode the temperature set point of the comfort
●
period must be higher than the setback period.
In Cool mode the temperature set point of the comfort
●
period must be lower than the setback period.
The estimated Smart recovery time must be longer
●
than 15 minutes for an Smart recovery to be initiated.
Maximum Smart recovery time is one hour.
●
AUX heat will not be activated during the first half hour
●
of a Smart recovery. Then it will only be activated if nec-
essary to achieve the programmed temperature by the
beginning of the next period.
The Smart recovery temperature set point must be
●
achievable. If a desired smart recovery is repeatedly
ignored by your thermostat that is an indicator that you
should modify your program so that the recovery can be
achieved within the 1 hour limit.
A Smart recovery may not be initiated for 48 hours
●
after the units programs have been changed. This allows
the unit to gather the data necessary to predict a Smart
recovery time.

4.2.10 FILTER LIMIT

Your thermostat will warn you that your HVAC systems
air filter should be changed after the systems fan has run
the number of hours that this setting has been pro-
grammed for. A general rule of thumb is to assume that
the fan will run at 1/3 duty cycle. A 90 day filter will then
be good for 90*24/3=720 hours. This is the default value.
Setting the filter counter limit to 0000 will disable the
change filter indicator. Valid entries are from 0 to
2000hrs.

4.3. ADVANCED FEATURES AND OPERATION

4.3.1 EMERGENCY HEAT

To use an emergency heat system, press the MODE
●
button repeatedly until the EMER HT is shown along the
top of the display. The unit is in emergency heat mode
ready to control your emergency heating system. In heat
pump systems, the emergency heat terminal is often
wired to W1 the AUX heat terminal.
Press temperature UP or DOWN keys until your
●
desired temperature is displayed in the HEAT SET area of
the display.
Freeze protection is also provided at this terminal. See
●
FREEZE PROTECTION.

4.3.2 FAN MODES

Your thermostat provides three fan modes. They are
AUTO, CLEAN, and ON. The fan may be controlled by
your units program, or the program may be overridden
by pressing the FAN button and selecting another mode.
Appropriate indicators are visible along the top of the
units display when active.
4.3.2.1 FAN AUTO
FAN AUTO denotes that the fan will run only to fulfill your
heating and cooling requirements.
4.3.2.2 CLEAN
This enables the CLEAN CYCLE
alone in the display denotes that the fan is maintaining
the programmed minimum run time; it will also run addi-
tional time as required to maintain temperature control.
The algorithm used avoids additional fan time when the
minimum run time has been met over the last hour
through temperature control. Minimum fan run times are
met by running one third the hourly requirement at twen-
ty minute intervals.
4.3.2.3 FAN ON
FAN ON denotes that your system fan will run continu-
ously.
