1.1.1 c.pCO controller functions
The software application for the electronic microprocessor controller, series c.pCO, was designed to manage Rooftop units.
Through appropriate configuration, this gives the possibility of managing a wide range of units with relevant specific fun
-
ctionalities.
Management of Rooftop units means monitoring that all component parts operate safely throughout the various operating
cycles.
The family of c.pCO electronic microprocessor controllers includes various module sizes. The software is flexible to the ex -
tent that the use of modules is optimized, meaning the modules used for reach application are those having the necessary
number of inputs and outputs.
The c.pCO board is connected to the various modules and communicates with them via a high speed, highly reliable field
bus.
The controller user interface consists in a colour, 4.3” touch-screen display.
