11.2 Makeup and mode of operation of the
controller
PID control controls the main controlled variable according to the defined setpoint.
The controller can contain max 2 sequences in the following combinations:
 One sequence: Sequence 1 or Sequence 4.
 Two sequences: Sequence 1 and 4.
Seq. 1
Setpoint
low
The "Setpoint low" (heating setpoint) is assigned to sequence 1.
Its output signal acts reverse to the load (inputs variable).
Example for heating: Outside temperature  , sequence 1 .
The "Setpoint high" (cooling setpoint) is assigned to sequence 4.
Its output signal acts reverse to the load (input variable).
Example for cooling: Outside temperature  , sequence 4 .
Functions "Heat demand" (see Section 10) and "Refrigeration demand" (see
Section 10.2) process the controller's output signal. The settings are described in
the corresponding chapters.
