Mechanical design
The unit consists of two parts:
∂ A plastic housing which accommodates the electronics, the operating elements and
the built-in room temperature sensor
∂ A mounting base
The housing engages in the mounting base and snaps on.
The base carries the screw terminals. The DIP switches are located at the rear of the
housing.
