ATTACH THERMOSTAT TO SUBBASE

WE RECOMMEND THAT YOU SET OPTION SWITCHES TO DESIRED POSITION BEFORE ATTACHING ON SUBBASE (see OPERATION). WE ALSO RECOM-

MEND THAT YOU PROGRAM THE THERMOSTAT WITH BATTERY INSTALLED BEFORE ATTACHING ON SUBBASE (see OPERATION GUIDE for program- ming instructions).

POWER TO THERMOSTAT MUST BE OFF BEFORE ATTACHING THERMOSTAT TO WALL. FAILURE TO TURN OFF POWER BEFORE ATTACHING THERMO- STAT MAY CAUSE EQUIPMENT DAMAGE DUE TO RAPID COMPRESSOR CYCLING.

To attach thermostat to subbase, line up the plastic snap guides at the top of the thermostat and the 4 connector pins on the thermostat with the connectors near the top right section of the subbase (when viewed from the front). Gently pivot the thermostat down until the 9-pin connec-

tors and the plastic snaps lock into place (see fig. 7). 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.

REVERSING VALVE DELAY OPTION

The diode designated as CR5 controls whether or not there will be a delay in reversing valve switching (see fig. 8). With the diode installed and operational, there is no delay. If the diode is not operational or is disconnected, there will be a six-second delay before the reversing valve is switched.
