HARDWARE RESET: The Hardware Reset button (labeled “HW
RST”) is a small round push button that is located towards the
right side if 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 if 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, than return to normal. The thermostat will still retain the current day
and ttime even after a Software Reset has been performed.
COMPRESSOR PROTECTION BYPASS: This optional feature permits the installer
or service technician to temporarily disable the built in compressor protection
delays. This is most useful for diagnosing and testing the heating and cooling
systems after installation is complete, and should not be used during normal
operation. To activate this feature, press and hold both the NEXT and HOLD
buttons, while also perform a single press of the Hardware Reset button (the LCD
display screen will become fully populated). Continue to hold the NEXT and
HOLD buttons until the LCD display screen returns to normal. All compressor
protection delays (in all modes of operation) will be disabled for 5 minutes. After
the 5-minute duration has expired, the thermostat will return to normal operation
automatically.
