6 Control loops
An overview of the control loops in the installation can be found under the 'Control
Loops' link in the navigation window. It always shows the actual (measured) value, the
corresponding setpoint and the difference between them. To obtain the overview, the
installation should have a structure for the house addresses that permits an optimum
representation of the system using novaWeb. The requirements for such a structure for
the house addresses are described in the programming manual for novaWeb EYW300
(document 7001050).

Cooling Water Temp 16.1 °C 16 °C 0.1 °C
To facilitate the handling of your Control Loops the deviation (or difference) is shown
with a green background for very small deviations, olive for small deviations and yellow
for large deviations. Like this the user can see very fast if he needs to act on any of
them.
The distinction between very small, small and large deviation is made regardless of the
type of control loop or the setpoint's unit (e.g. °C, Pa, rh).:
Setpoint > 10 units
Setpoint • 10 units
