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. This protection is also present in the heat mode
of operation on single stage heat pump systems to protect the compressor.
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.
Low Battery Detection
This thermostat requires two (2) new,
properly installed “AA” Alkaline batteries
to maintain the system clock and to provide
proper thermostat power when 24 volt AC
power fails or is not connected to the
thermostat. When the batteries start to become
too weak to provide proper operation, the
thermostat will begin to display a low battery indicator.
The low battery indicator is provided to inform the user when the batteries
require immediate attention. We recommend replacing the batteries as soon
as the low battery indicator appears. If the batteries are not replaced after
the low battery indicator first appears, the thermostat may not provide
proper heating or cooling system operation.
Even if the low battery indicator does not appear, the batteries should be replaced
at least once a year, or if you plan on leaving the premises for over a month.
This thermostat can be powered from 24 volts AC or battery power. To determine
if 24 volt AC power is connected to the thermostat, refer to the installation and
wiring diagram section. If you cannot determine how this thermostat is powered,
call a professional service technician to determine the type of installation and the
proper operation of your system.
Resetting the Thermostat
The Reset feature allows the user to completely reset the thermostat to register
new manual switch settings. To erase all entered programs, current time of day,
day of week and other user settings, gently press the
RESET
button using a paper
clip or a small pencil tip. This will return all thermostat settings to their default
values and register all new manual switch settings for proper operation.
Non-Volatile Memory
In the event of a power failure, the Non-Volatile Memory feature allows all
settings to be recovered, eliminating the need to reset temperature and
differential settings. When AC power is restored after an outage, all settings are
retrieved from memory and reinstated.
