FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of heating
and cooling systems. The user may program up to four
time/temperature settings per 24 hour period. The ther-
mostat stores independent heating and cooling programs
for each day of the week. The thermostat will store both
heating and cooling programs simultaneously. Three
"AA" Energizer
®
batteries will maintain the stored pro-
gram for approximately one year, if incoming power
should fail. If power failure is extensive and the program
is lost, after power restoration, the thermostat will auto-
matically maintain a factory preprogrammed heating tem-
perature of 64°F or a cooling temperature of 82°F.

Do not exceed the specification ratings.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
To prevent electrical shock and/or equipment
damage, disconnect electric power to system, at
main fuse or circuit breaker box, until installation
is complete.
Do not use on circuits exceeding specified volt-
age. Higher voltage will damage control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or pri-
mary control to test. Short or incorrect wiring will
burn out thermostat and could cause personal
injury and/or property damage.
