ON-OFF control, P (PD) control and PID control can be used for cooling
applications. This is accomplished by setting OUT1 to DIRT (direct action).
The other functions for
control, control
and control are the same as descriptions in section 3-4 for heat
only control. The only difference is that the output variable (and action) for
the cool control is inverse to the heat control, such as the following diagram
shows:
cool only ON-OFF cool only P ( PD )
