Heat demand requirements
The maximum value of the control inputs from1 to 6 is
transmitted to the output. Only the highest value is
passed. The value of the datapoint “Demand” will be
set to “1”, when the maximal value is greater than ze-
ro.

Lighting control
Several functions can be realized:
-
Full-automatic control
A typical application for the fully automatic control is
the lighting of a corridor.
The light is turned on in presence when the current
brightness value is below the threshold. By manual
operation, the light can be switched on or off for a
specific time.
-
Semi-automatic control
The semiautomatic mode allows the user or residents
to turn the lights on and off manually. The semi-
automatic only intervenes when the light was ‘forgot-
ten’. A typical application is an office room with sever-
al desks.
The light will not be switched on automatically. The
semi-automatic switches the light off when the current
brightness value is above the threshold or when for a
defined time presence is no longer detected.
-
Simple control
The simple control only evaluates the brightness and
can be used, for example, for a store window.
The light turns on if it is too dark, and automatically
turns off when the brightness limit is reached.
