Before you begin programming your thermostat, you should
be familiar with its features and with the display and the loca-
tion and operation of the thermostat buttons. Your thermostat

the cover, line up the cover with the base and press until the
cover snaps onto the base.

CONFIGURATION MENU
The configuration menu allows you to set certain thermostat
operating characteristics to your system or personal require-
ments.
Press RUN to make sure the thermostat is in the run program
mode, then press PRGM and RUN 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.
OPERATION
Press HOLD to change to the next menu item or press TIME
to go backwards to the previous item in the menu. To exit the
menu and return to the program operation, press RUN. If no keys
are pressed within fifteen minutes, the thermostat will revert to
normal operation.
1) Select Temporary Hold Time
- The thermostat can hold any
temperature you set it to for the amount of time you select on
this option. Your choices are 0:00 to 8:00 hours in 15 minute
increments. 0:00 disables the function
Example:
1. You have selected 3:00 hours for the Temporary Hold
time period.
2. With the thermostat set to Heat or Cool, press HOLD
for approximately five seconds
until HOLD time (3:00
indicating 3 hours) appears as a setting reminder.
3. After releasing the button,
“HOLD”
on the display will
blink.
4. Use
or
to set the temperature to your prefer-
ence. The thermostat will maintain this temperature
setting for 3 hours with
“HOLD”
blinking to remind you
it is in Temporary Hold. After 3 hours the thermostat will
go back to the program temperature and
“HOLD”
will
no longer blink or display.
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 1.5°F.
3) Select backlit display
- The display backlight improves
display contrast in low lighting conditions. Selecting backlight
ON
will keep the light on for a short period of time after any
key is pressed. Selecting
OFF
will keep the light off.
