2 GENERAL DESCRIPTION
2.1 General
Microtech® III is a system for controlling single or dual-circuit air-cooled liquid chillers. Microtech®
III controls compressor start-up necessary to maintain the desired heat exchanger leaving water
temperature. In cooling mode it controls the operation of the fans to maintain the correct
condensing pressure in each circuit.
Safety devices are constantly monitored by Microtech® III to ensure their safe operation.
Microtech® III also gives access to a Test routine covering all inputs and outputs. All Microtech® III
controls can work in accordance with three independent modes:
Local mode: the machine is controlled by commands from the user interface.
Remote mode: the machine is controlled by remote contacts (volt-free contacts).
Network mode: the machine is controlled by commands from a BAS system. In this case, a data
communication cable is used to connect the unit to the BAS.
When the Microtech® III system operates autonomously (Local or Remote mode) it retains all of its
own control capabilities but does not offer any of the features of the Network mode.
