1INTRODUCTION
1.1 Introduction
The programmable controller of the c-pro 3 micro CHIL erie are device tudied for the management of ingleandtwo-circuit
chiller -heat pump up to three crollcompre or for each circuit.
They make u e of the programmable controller , of the I/Oexpan ion and of the remote u er interface belonging tothe c-pro 3 erie
and are programmed with an application oftware implemented with the development environmentUNI-PRO 3.
They are available in built-in and in blind ver ion; the blindver ion mu t be u ed with a remote u er interface.
The controller can manage air to water and water to waterchiller -heat pump ; through the CAN communication portthe controller
can al o communicate with an externaldriver (EVDRIVE03) for bipolar tepper electronic expan ionvalve .
They can be powered in alternating current (12 VAC). Through the programming port it i po ible to make the upload and the
download of the configuration parameter (u ing a common USB peripheral); through the RS-485 one, with MODBUS communication
protocol, it i po ible to connect the device to the et-up oftware y tem Parameter Manager or to the plant monitoring and
upervi ion one via Internet CloudEvolution in tead. Through the CAN communication port it i finally po ible to connect the device to
the I/O expan ion, to the remote u er interface and to the external electronic expan ion valve driver.
The application program i capable of managing air-to-water and water-to-water unit , mono or twin circuit.
The following are only ome of the numerou control function available:
Available unctions
Manage up to 3 croll compre or for each circuit
Manage compre or with cooling – heating mode
Manage fan with pha e-cut module
Manage electronic valve EVDRIVE03 for each circuit
