HARDWARE RESET: The Hardware Reset button
(labeled “HW RST”) is a small round push
button that is located towards the right side of
the circuit board, just below the battery holder.
Pressing this button will cause the LCD display
screen to become fully populated, the heating
and cooling load relays to cycle off, read the
position of the Hardware Setup Option
switches, and will perform an internal system
check of the thermostat components. If your thermostat appears to be
acting in an erratic manner, pressing the Hardware Reset button may
remedy this behavior. The temperature programs are not erased when a
hardware reset is performed, however the clock will have to be changed to
match the current day and time.
SOFTWARE RESET: The Software Reset button
(labeled “SW RST”) is a small round push
button that is located towards the left side of
the circuit board, just below the battery holder.
A Software Reset is used to erase all heating
and cooling temperature programs, and any
user-adjustable software values such as: Swing,
Offset, and Calibration, to their original factory
default values. To perform a Software Reset,
press and hold the Software Reset button for at
least 5 seconds. The LCD display screen will become fully populated,
then return to normal. The thermostat will still retain the current day and
time even after a Software Reset has been performed.
