Control Modes

You can select the Heating, Cooling or Heating and cooling control modes.

Modes can be switched automatically, via an object or with a button. The transition takes place automatically via the button or Heating/Cooling control value object.

Both heating and cooling are controlled by comparing the setpoint and the actual temperature.

The controller can control the connected heating/cooling systems via corresponding switch telegrams or continuous correcting variables. In this way, both PI controls and 2-step controls can be parametrized.

There are four operating modes for differentiated control with different requirements. Each mode has programmable setpoints. During ongoing operation, you can temporarily move the setpoints within adjustable limits, or move them jointly for several operation modes. Optionally, the basis for the setpoints can also be moved.

Additional functions of the room temperature control unit are:

• Selection of the operation mode after the bus voltage returns

• Status information
