FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of multi-
stage systems. Use this thermostat for applications re-
quiring up to three stages of heat and up to two stages of
cool. Indicator lights show the system status. The user
may program up to four time and two temperature settings
per 24 hour period and may program each day independ-
ently. The thermostat will store both heating and cooling
programs simultaneously. A 9 volt Energizer
maintain the stored program for approximately one week,
if incoming power should fail. If power failure is extensive
and the program is lost, after power restoration, the
thermostat will automatically maintain a factory
preprogrammed heating temperature of 64°F or a cooling
temperature of 82°F.
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
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 heat anticipator and could cause per-
sonal injury and/or property damage.
