ATTACH THERMOSTAT TO SUBBASE

IT IS RECOMMENDED THAT YOU SET OPTION
SWITCHES TO DESIRED POSITION BEFORE ATTACH-
ING ON SUBBASE  
(see OPERATION).  IT IS ALSO
RECOMMENDED THAT YOU PROGRAM THE
THERMOSTAT WITH BATTERIES INSTALLED BE-
FORE ATTACHING ON SUBBASE 
(see OPERATION
GUIDE
 for programming instructions).

POWER TO THERMOSTAT MUST BE OFF BE-
FORE ATTACHING THERMOSTAT TO WALL.
FAILURE TO TURN OFF POWER BEFORE AT-
TACHING THERMOSTAT MAY CAUSE EQUIP-
MENT DAMAGE DUE TO RAPID COMPRESSOR
CYCLING.

To attach thermostat to subbase, line up the plastic snap
guides at the bottom of the thermostat and the three
connector pins on the thermostat with the connectors
near the bottom left section of the subbase (when viewed
from the front).  Gently pivot the thermostat up until the six

pin connectors and the plastic snaps lock into place (see
Fig. 12).  Be gentle when attaching thermostat.  If the
thermostat does not seem to be attaching to the subbase
easily, make sure that the connector pins and plastic
snaps are properly aligned, and that excess wire is
pushed into the wall.  Damage to the thermostat may
occur if force is used.
