4. Configuration and operation

This section describes how the controller:

• Is configured

• Is operated

We have decided to work on the basis of the example we went

through previously, i.e.

• Difference thermostat,

• Difference pressostat

• Two-sensor thermostat.

The example is shown overleaf.
