Controller
Parameter Meaning
tyP Controller type/control direction
0 = 2-state controller, inverse (heating) / 1 = 2-state contr., direct (cooling)
SPL Lower setpoint limit
The setpoint SP can be set starting from this limit.
SPH Upper setpoint limit
The setpoint SP can be set up to this limit.
Pb Proportional band
influences the P-response of the controller.
Pb
With =0, the controller action (e.g. PID) is ineffective.
dt Derivative time
influences the D-response of the controller.
dt
With =0, the controller has no D-response.
rt Reset time (integral-action time)
influences the I-response of the controller.
rt
With =0, the controller has no I-response.
Cy Cycle time
The cycle time has to be selected so that the energy supply to the process is
virtually continous, while not subjecting the switching elements to excessive
wear.
