communication cable or a crossover network cable.
Ventilation application, overview of functions
The controller comes loaded with programs for control of a ventilation unit. The temperature
controller is based on a supply air PI-controller for heating control with a pre-programmed
set of control modes. A number of different control functions as well as analogue and digital
input and output functions can be bound to this controller. Certain functions are necessary,
while others can be considered optional. This flexibility means that what is shown in the
display may differ from one unit to another, depending on which functions have been
selected.
Functional choices are not made in the operator level, but in the Admin access level by
educated personnel with specialised knowledge. The same applies to other configuration.
The program for an air handling unit contains, apart from other things, the following
functions:
Different temperature control modes:
• Supply air temperature control, with or without outdoor temperature
compensation.
• Room temperature control (cascade control).
• Extract air control (cascade control).
• Seasonal switching between supply air temperature control and room/extract air
temperature control.
• Outdoor compensated room/extract air control.
