14.2.1 Operating principle
PID control controls the main controlled variable according to the defined setpoint.
14.2.2 Setpoints
Controllers 2+3, basic type A; controllers 1+2+3, basic type U:
Specific setpoints can be predefined for the
Comfort and Precomfort modes.
Controllers 2+3 basic type C and basic type P:
Setpoints can only be predefined for
Comfort mode.
We differentiate between the following:
Heating setpoints (sequence 1+2+3)
Cooling setpoints (sequence 4+5)
The following functions can influence the setpoints:
Universal shift (see section 15.6)
Remote setpoint adjuster, absolute (see section 8.7 )
