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 multi-
stage systems. Use this thermostat for applications
requiring 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/temperature settings per 24
hour period. The thermostat stores settings for a five-day
(weekday) program and a two-day (weekend) program.
The thermostat will store both heating and cooling pro-
grams simultaneously. A 9 volt Energizer® battery will
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.
