19. Verify that the system and its fan are operating
properly. When set to a high temperature, the heating
system should provide warm air after a short time.
Likewise a cooling system should provide cool air after a
short time. Usually sound from the furnace and air
conditioning units can be heard while they are running.
The rush of moving air should be heard within a short
time after either has been started.
20. Your installation is now complete.
5 OPERATING BASICS

display. They are used to adjust set temperatures, and
make other setting changes.
●
Pressing these keys once will adjust a setting one step
in the associated direction.

If there are many choices for a value, usually that
setting will advance while holding one of these keys.
Some settings though, must be changed one press at a
time.
5.2 SET DAY AND TIME

Return the dial to its
RUN
position.
5.3 TEMPERATURE CONTROL MODES
When a unit has first been powered up with the dial in
the
RUN
position, your thermostat will begin to control
your heating and/or air conditioning system according to
it's default program. There is a 4-position slide switch to
change temperature control modes. Slide the switch to
the mode you would like to use.
5.3.1 HEAT
●
Use HEAT mode to control your furnace and warm
your home.
●

While heating is active,
HEAT
will flash
●
If a second stage of heat is called for the flashing rate
increases.
5.3.2 COOL
●
Use COOL mode to control your air conditioner,
cooling your home.
●
In COOL mode, COOL is displayed right of the set
temperature.

Use AUTO CHANGE mode to allow your thermostat to
switch between HEAT and COOL modes automatically.
Slide the mode switch to
AUTO
and
AUTO CHANGE
will
be displayed above the set temperature. You can
determine whether your thermostat is in HEAT or COOL
mode by whether HEAT or COOL is visible in the set
temperature area of the units display. Initially HEAT or
COOL may not be active until a determination is made
that HEAT or COOL is necessary.
●
The programmed temperature for a given mode will be
used as the set temperature for that mode.

may be adjusted within the range from 1 to 4 hours. The
temporary set temperature(s) will be used for the
duration of the OVERRIDE.
