9.4.2 Operating principle
PID control controls the main controlled variable according to the defined setpoint.
Control mode
The position of the CH OVER digital input determines whether the heating or
cooling sequences are enabled:
Enabling the
sequences
• CH OVER = 0 signifies "enable cooling sequences"
• CH OVER = 1 signifies "enable heating sequences"
The "analog output" aggregate must be configured for heating and cooling
sequences, i.e:
Note
• Heating (sequence 1 and / or sequence 2) and
• Cooling (sequence 4 and / or sequence 5)
For more detailed information, refer to section 9.5 “Sequence controllers, output
assignments”.
9.4.3 Setpoints
You can preselect individual setpoints for the Comfort and Economy modes.
Basic type U,
controller 1
We distinguish between the setpoints for:
• Precontroller "Heating" (sequence 1)
• Precontroller "Cooling" (sequence 4)
