INTRODUCTION 

1.1

 

Introduction 

EV3 CHIL and EVD CHIL are controllers for running single-

circuit air-water and water-water chillers with up to two 

compressors. 

 

EV3 CHIL is available in the standard 74x32mm format with 

built-in user interface consisting of a double custom display, 

with decimal point and function icons, and four touch keys. It 

guarantees IP65 protection for easy cleaning. 

 

EVD CHIL is available in standard 4-module DIN format, in a 

blind version that can be connected to a remote user interface 

(EV3K01) if required. 

 

These controllers are capable of running compressors and fans 

of both the on-off and modulating types. 

 

EV3 CHIL is available with a 12VAC power supply, while EVD 

CHIL can be supplied with a 115... 230VAC power supply. 

 

EV3 CHIL is designed to be installed on a panel with snap-in 

brackets, while EVD CHIL is fitted to a DIN rail in a control 

panel.
