1. IMPORTANT RECOMMENDATIONS The symbol alerts the user of non-insulated “dangerous voltage” within the product area that is sufficiently high to constitute a risk of electric shock to persons. The symbol alerts the user of important operating and maintenance (assistance) instructions found in the documentation attached to the device. Dixell Srl cannot accept any liability for damages caused by modems that are not supported. Dixell Srl reserves the right to modify this manual without prior notice.
It is good practice to bear the following in mind for all Dixell products: o o o o o o Prevent the electronic circuits from getting wet as contact made with water, humidity or any other type of liquid can damage them. Comply with the temperature and humidity limits specified in the manual in order to store the product correctly. The device must not be installed in particularly hot environments as high temperatures can damage it (electronic circuits and/or plastic components forming part of the casing).
2. INTRODUCTION iPRO is the range of programmable controllers manufactured by Dixell. The range consists of programmable controllers, I/O expansions, drivers for electronic valves and graphical interfaces adapted to cover any type of application in the air-conditioning sector, cooling sector and any relative area. As the system is one of the most technologically advanced, it is flexible and can be customised for it to be adapted to the user's particular requirements. 3.
