This thermostat includes an automatic compressor protection feature to avoid
potential damage to the 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
heat pump systems to protect the compressor.
NOTE: The installer can bypass the compressor protection feature by pressing
the RESET button. This will erase all user program settings, returning all settings
to their default values. This should only be used during installation for testing
purposes or to reset a thermostat to regain normal operation.
This thermostat requires two (2) new, properly
installed “AA” Alkaline batteries 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.
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 or batteries are reinserted, all settings
are retrieved from memory and reinstated.
Status Indicators
HEAT: This will turn on whenever the
system switch is in the HEAT mode.
“HEAT” will flash when the heating
system is running.
