AIR FLOW position, the display shows half degree
differences between the heated and unheated sensors in the
air flow module. When the air is dead calm, this reading
often reaches 45. With strong air flow, it drops below 15.
The program keeps an eye on this air flow number and
when it rises above 18 (the default setting), it shuts off the
compressor. The procedure to change this setting is similar
to changing the thermostat’s SET temperature.
Enhancing and Expanding the
Smart A/C Controller
This project has enormous expansion capabilities. The
optional parts RLY2, RLY3, SEN4, LED4, LED5, S6, RESN,
DIPSW1, and associated parts are shown in the schematic.
The circuit board was designed to include these parts.
