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.
