Press the VACATION button when
you return to resume normal operation.
AUTO CHANGEOVER
Your Thermidistat Control provides
complete, automatic control over heating
and cooling with auto changeover. Auto
changeover means your system will
automatically heat or cool as needed to
maintain your temperature set points.
Auto changeover makes life easier because
you no longer have to manually switch
the thermostat between heating or cooling
operation. Just set your heating and
cooling temperature set points and let the
Thermidistat Control do the rest!
25
NOTE: If auto changeover is not necessary in your
area of the country, your installer may
disable the AUTO mode.
SMART RECOVERY
Smart recovery is a feature of your new
Thermidistat Control designed to save energy by gradually adjusting temperatures.
When it’s time for a programmed
temperature change, smart recovery
begins working in advance, turning the
system on and off as needed to slowly
adjust the indoor temperature. During
these transition periods, you may notice
that the actual temperature and your
temperature setting don’t match. That’s
smart recovery in action, adjusting
temperatures in small increments for
greater energy efficiency. This is more
26
energy efficient than simply allowing the
system to operate at full capacity until the
desired temperature has been met.
NOTE: The Thermidistat Control will start adjusting
the temperature 1.5 hours before the scheduled
temperature change.
WHAT IF…
AUXILIARY HEAT indicator is displayed…
The AUXILIARY HEAT indicator appears on
the heat pump version of the Thermidistat
Control only. It is displayed when your

for several days if needed. Press the HOLD
button to resume normal system operation.
NOTE: This indicator does not reflect a problem
with your system.
WHAT IF…
OUT Indicator is displayed…
The OUT indicator reminds you that your
system is in vacation mode. This function
automatically adjusts the temperature and
humidity settings to levels appropriate for
when you’re away. Press the VACATION
button to resume normal system operation.
NOTE: This indicator does not reflect a problem
with your system.
EQUIPMENT ON Indicator is displayed…
When the cooling equipment is operating, the
word COOL preceded by a small
triangle is displayed below the cooling set
point. When the heating equipment is

operating, the word HEAT preceded by a small
triangle is displayed below the heating set
point. If the equipment turn on is being
delayed, the triangle and the word will flash.
NOTE: This indicator does not reflect a problem
with your system.
You have a power outage…
An internal power source eliminates the
need to reprogram the Thermidistat
Control after power outages. The comfort
schedule you have entered will be
maintained indefinitely. Clock will run for
8 hours.
WHAT IF…
