Installation Tips
Mount Thermostat
Align the 4 tabs on the subbase with
corresponding slots on the back of the
thermostat, then push gently until the
thermostat snaps in place.
Battery Installation
Battery installation is recommended even if thermostat is hardwired
(C terminal connected). When thermostat is hardwired and batteries
are installed, the thermostat will activate a compressor delay of 5
minutes when the thermostat detects a power outage from the
hardwired power supply.
Important:
High quality alkaline batteries are recommended.
Rechargeable batteries or low quality batteries
do not guarantee a 1-year life span.
Insert 2 AA
Alkaline batteries
(included). High
quality alkaline
batteries are
recommended.

Wall Locations
The thermostat should be installed approximately 4 to 5 feet above the
floor. Select an area with average temperature and good air circulation.
Installation Tip
Pick an installation location that is easy for
the user to access. The temperature of the
location should be representative of the
building.

Thermostat Quick Reference
System Operation
Indicators:
The COOL ON, HEAT ON
icon will display when the
Set At
COOL, HEAT is on.
Indicates
the current
room
temperature.
Low Battery Indicator:
Replace batteries when
indicator is shown.
NOTE: The compressor delay feature is active
if these icons are flashing. The compressor
will not turn on until the 5 minute delay has
elapsed.
Important
The low battery icon is displayed when the AA
battery power is low. Whenever the thermostat
detects low battery voltage from the AA batter-
ies, the low battery icon will begin flashing on
the screen for 21 days (if the batteries are not
changed). If the batteries are not changed 22
days after the thermostat detects low battery
voltage, the thermostat screen will only show
the flashing battery icon until buttons are
pressed. If the batteries are not changed 43
days after the thermostat detects low battery
voltage, the thermostat screen will only
show the flashing battery icon until buttons
are pressed and the set points will offset to
85°F/29°C in cooling and 55°F/13°C in heating.
At this stage, set point changes can be made
temporarily but, the set points will change back
to defaulted values after a 4-hour period. The
thermostat will continue to perform this low
battery flashing, temperature offset condition
until the internal voltage threshold is reached.
When the thermostat internal voltage threshold
is reached, all relays will be opened and the
thermostat will become inoperable until new
batteries are installed.
