This document gives all the necessary information to configure the regulation system and also givesthe various menus and their displays.This document must only be used when the regulation system configuration software is not available.Nevertheless, it is used as a reference documentThe indices used (1 and 2) correspond to the unit refrigerant circuits. For single circuit units, onlyindex 1 is to be taken into account.Scrolling through menus and sub-menus as well as modifying parameters in the menus and sub-menus are mode with "UP" and "DOWN", "+" and "-" keys located on the front face of the regulationmodule system "UP" and "DOWN" keys allow to scroll from one menu or one parameter to another.They also allow to move from one character to the other in a parameter when it has more than one"+" and "-" keys allow to modify the value of the parameters when it can be modified "=" keyincrements the value and "-" also allow the scrolling down to a sub-menu when the correspondingmenu header is displayed.Pressing more than 3 seconds on I, unit will be reset.
