Continuous and Switching PI Control

For the PI control, the control value is calculated from a proportional and an integral share. The calculation is governed by the following parameters:

• Temperature difference between actual value and setpoint

• Proportional range

• Reset time

In this way, the controller can correct the room temperature accurately. The corresponding control value is transferred via a 1 bit/1 byte value to the bus.

The standard control parameters for the most common system types are already installed in the controller.

Heating/cooling speed:

• Hot water heating (5K/150 min)

• Underfloor heating (5K/240 min)

• Electrical heating (4K/100 min)

• Cooling ceiling (5K/240 min)

• Split unit (4K/90 min)

• Fan coil unit (4K/90 min)

• User defined

You can also set the control parameters for the proportional range and the reset time manually, but you should know exactly which actuators are connected and the control conditions in the room.
