ON – WHEN TERMINAL E IS POWERED, THE DAMPERS GO TO MINIMUM POSITION
ON – WHEN COMPRESSOR NUMBER ONE IS ON, THE DAMPERS GO TO MINIMUM POSITION
If switches 6 and 7 are both off, the damper locks out and min. pos. must be external to C-TRAC. The C-TRAC will
continuously modulate the damper during mechanical cooling. If there is on economizer, set switches 6 and 7 to the ON
position.
