PROGRAMMING AND REGULATION
MICROPROCESSOR CONTROL
INTRODUCTION
The control system consists of a microprocessor base circuit fitted in the unit and a user interface which can
be either local or remote.
Sophisticated algorithms enable monitoring and protection of unit components and the user interface
provides clear information on unit status and any current alarms.
The main functions of the microprocessor control are:
•
chilled water temperature regulation
•
anti-freeze
protection
•
compressor protection and timing
•
alarm code signalling and collection for cumulative remote alarm communication
•
compressor run hour counter
•
remote on/off command
•
LAN
connection
•
Serial output connection.
