Control tailored to the building
Desigo PXC controllers are used for control of selected HVAC and technical systems. Controller variants and I/O expansions are selected for the project.
Desigo PXC for building-wide automation
Desigo PXC controllers provide a programmable automation layer for HVAC and other compatible building systems. Different hardware models and expansion modules address different point counts, mounting arrangements and system architectures.
Typical applications
- Air-handling equipment with fans, heat recovery, temperature and pressure control.
- Heating and cooling substations, pumps and heat exchangers.
- Building-wide schedules, energy-related operating modes and equipment coordination.
- Integration of supported third-party technical systems.
Engineering and integration
Controller engineering includes I/O mapping, functional logic, trends, alarm rules and communication objects. Many Desigo solutions support BACnet integration; availability of BACnet/SC, particular engineering tools and remote access functions varies by controller generation and installed software. Confirm the exact product requirements with the manufacturer before designing security or interoperability around these functions.
Modernisation without disrupting operations
Before upgrading an existing plant, prepare an inventory of controllers, I/O modules, applications and field devices. Assess the required downtime and test the replacement logic before handover. Retain operational records so the owner can support and extend the system over time.
