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 two stages of heat and/or cool. Indicator
lights show the system status. The user will program two
time/temperature settings per 24 hour period. The ther-
mostat stores programs for seven independent days. The
thermostat will store both heating and cooling programs
simultaneously. A 9 volt Energizer
the stored program for approximately one week, if incom-
ing power should fail. If power failure is extensive and the
program is lost, after power restoration, the thermostat
will automatically maintain a factory preprogrammed heat-
ing 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.
