1 INTRODUCTION
1.1 Introduction
The programmable controllers of the c-pro 3 micro CHILseries are devices studied for the management of singleandtwo-circuits
chillers-heat pumps up to three scrollcompressors for each circuit.
They make use of the programmable controllers, of the I/Oexpansions and of the remote user interfaces belonging tothe c-pro 3 series
and are programmed with an applicationsoftware implemented with the development environmentUNI-PRO 3.
They are available in built-in and in blind version; the blindversions must be used with a remote user interface.
The controllers can manage air to water and water to waterchillers-heat pumps; through the CAN communication portthe controllers
can also communicate with an externaldriver (EVDRIVE03) for bipolar stepper electronic expansionvalves.
They can be powered in alternating current (12 VAC). Through the programming port it is possible to make the upload and the
download of the configuration parameters (using a common USB peripheral); through the RS-485 one, with MODBUS communication
protocol, it is possible to connect the devices to the set-up software system Parameters Manager or to the plants monitoring and
supervision one via Internet CloudEvolution instead. Through the CAN communication port it is finally possible to connect the devices to
the I/O expansion, to the remote user interface and to the external electronic expansion valves driver.
The application program is capable of managing air-to-water and water-to-water units, mono or twin circuit.
The following are only some of the numerous control functions available:
