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 5-day (weekday) and 2-day (weekend) periods. The thermostat will store both heating and cooling programs simultaneously. Three "AA" Energizer® batteries will maintain the stored program 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 automatically maintain a factory preprogrammed heating temperature of 64°F or a cooling temperature of 82°F.

PRECAUTIONS
