SOFTWARE RESET:
Software reset is used to erase ALL temperature events,
and to return all user-adjustable software settings back to

1. Verify the thermostat’s keypad is not locked.
2.
Move TEMPERATURE switch to OFF.
3.
Press and hold the UP, DOWN, and NEXT buttons all
at the same time for at least 5 seconds. When the LCD

buttons at that point the screen will return to normal.
The clock will have to be changed to match the current
day and time.
Battery Replacement
This thermostat is powered by two “AA” Alkaline batter-
ies. The batteries should be replaced AT LEAST once per
year to ensure reliable operation or sooner if the LO BATT
appears on the display screen. The batteries are located
on the back of the thermostat’s circuit board. The front por-
tion of the thermostat can be removed from the back half
by using the tabs on the top edge of the thermostat hous-
ing
(Figure 3.10 on page 12)
.
When installing new batteries, it is recommended using
only brand new “AA” size alkaline batteries. Please verify
the polarity markings shown in the battery compartment
before adding batteries to the compartment. When fin
-
ished, line up the front of the thermostat to the base, and
firmly press together to securely latch the front and back
halves together properly.

lated
• Thermostat to perform an internal system check of its
components

The temperature programs are not erased when a hard-
ware reset is performed, however the clock will have to be
changed to match the current day and time.

Anytime time the batteries are physically present in the
thermostat, there will be a visual indicator showing the life
of the battery. This will appear on the display screen
