Before you begin using your thermostat, you should be familiar
with its features and with the display and the location and
operation of the thermostat buttons. Your thermostat consists of
two parts: the thermostat cover and the base. To remove the
cover, gently pull it straight out from the base. To replace the
cover, line up the cover with the base and press gently until the
cover snaps onto the base.

Operating Features
Now that you are familiar with the thermostat buttons and display,
read the following information to learn about the many features of
the thermostat.
SIMULTANEOUS HEATING/COOLING SETPOINT
STORAGE — You can enter both your heating and cooling
setpoints at the same time. There is no need to re-enter the
thermostat at the beginning of each season.
TEMPERATURE SETTING — Press or until the
display shows the temperature you want. The thermostat will
keep the room temperature at the selected temperature.
°F/°C CONVERTIBILITY — The factory default setting is
Fahrenheit. If you need Celsius temperature setting, go to
menu mode and change the fifth option to C (see configura-
tion menu, page 5).
TEMPERATURE DISPLAY ADJUSTMENT — Your new
thermostat has been accurately set in our factory. However,if
you wish, you may adjust your new thermostat temperature
display to match your old thermostat. This can be accom-
plished (within a ±4° range) by going into the menu mode (see
configuration menu, page 5).

CONFIGURATION MENU

The configuration menu allows you to set certain thermostat oper-
ating characteristics to your system or personal requirements.
With the system switch in “OFF” mode, press and keys
at the same time to enter the configuration menu. The display will
show the first item in the configuration menu.
The configuration menu table summarizes the configuration
options. An explanation of each option follows.
Press and together momentarily to change to the next
menu item. To exit the menu, change the system switch from OFF
to HEAT or COOL. If no action is taken within fifteen minutes, the
thermostat will revert to normal operation.
2) Select FA or SL (Fast or Slow) Heating Cycle Rate—The
FA setting is frequently used for gas, oil or electric heat. The
SL setting produces a longer heating cycle which is normally
for hot water or steam (hydronic) systems. Both settings
produce very accurate temperature control and can be set to
your personal preference. FA cycles the system just under
1°F and the SL setting cycles at approximately 1.5F°.
3) Not Available
4) Select Compressor Lockout LOC OFF or ON—Selecting
LOC ON will cause the thermostat to wait 5 minutes before
turning on the compressor if the heating and cooling system
loses power. It will also wait 5 minutes minimum between
cooling cycles. This is intended to help protect the compres-
sor from short cycling. Some newer compressors already
