Unit Controller Operation - Daikin Clima-Flex CLIC Series Installation, Operation And Maintenance Manual

GENERAL DESCRIPTION
The pCOOEM+ is an electronically programmable microprocessor-based controller that is fully compatible (software and hardware)
with the pCO family of products and systems that include programmable controllers, user terminals, gateways, communication devices
and remote device management. These devices represent a powerful control system that can be easily linked with the vast majority of
Building Management Systems (BSM) available on the market.
The controller menu can be accessed from a touch screen, this screen has all the parameters and the operating status of the equipment.
The pCOOEM+ continuously performs pre-fault scans of the equipment status to prevent damage to parts and components if a fault
occurs.
The controller menu contains different screens and submenus that provide the operator or service technician with a complete overview
of:
1. User.
2. Maintenance.
3. Service Manufacturing
SYSTEM ARCHITECTURE
The general architecture of the controls uses the following
• Unit controller.
• E/S extension modules as required based on the unit configuration.
• Communications interface slave modules.
• The units in the architecture have a configuration based on a MASTER unit and unit E/S slaves, these slaves can be connected via
rs485 serial Modbus and can be configured from the configuration screen.
All E/S slave modules can be connected directly or via a wiring harness.
The connection order of the slaves can be from left to right or from right to left, always respecting the master as the main unit.
