be done prior to installation and before any programming to avoid loss during reset step.
High Temperature Safety Switch
NOTE: The installer can reset the thermostat and bypass the compressor protection
features by pressing the RESET button. This will erase all entered programs, current time
of day, day of week and other user settings and should only be used during installation
for testing purposes or to reset a thermostat to regain normal operation. This will return
all thermostat settings to their default values. The user will have to reprogram all of the
erased settings.
Compressor Protection
This thermostat includes an automatic compressor protection feature to avoid potential
damage to the cooling system from short cycling. This thermostat automatically provides a
5-minute delay after turning off the cooling system output to protect the compressor.
While the thermostat is in the HEAT mode of operation (selector switch in the HEAT position),
the thermostat will mechanically turn-off if the room temperature raises higher than 99˚F
(37˚ C). There is also a software feature that will automatically turn-off the thermostat in
HEAT mode if the temperature raises higher than 93˚ F (34˚ C).
