The C7000 control system offers operational reliability for
industrial applications in combination with two designs for
the user interface. The C7000IOC is responsible for the
control. The C7000 Advanced is optional and serves as a
convenient user interface.
Every air conditioning unit has its own controller, while all
controllers can be connected with one another via a bus
system.
Beyond the basic functions of air conditioning technolo-
gy, the C7000 control system offers its own interesting
functions, e.g. intelligent management of the high/low
pressure alarms, a constant fan speed regulation, which
introduces a further field of application, and time-based
functions such as:
- Week timer
- Unit sequencing within definable unit groups
A watchdog on the C7000IOC monitors the CPU function
and generates a reboot as soon as no CPU activity has
been detected for 0.5 seconds.
Up to 4 EAIO/EDIO boards for additional inputs and out-
puts can be inserted at right angles on the C7000IOC.
The C7000 control system manages 4 buses:
1. IIC bus for communication between the C7000 I/O
controller and the EAIO/EDIO
2. RS485 IO bus for communication among the air con-
ditioning units
3. RS485 BMS bus for communication with a building
management system
4. RS485 component bus (e.g. for EVD driver; µPC)
