ABB Cylon® Building Automation · Southern California
ABB Cylon building automation & HVAC controls in Southern California.
C.E. Mechanical is an ABB Cylon Approved System Integrator providing commercial building automation design, installation, programming, integration, troubleshooting, retrofit, and service. Our controls work is backed by the mechanical field experience needed to verify the equipment behind the BAS—not just what the screen reports.
From field device to operator
A BAS is only useful when every layer tells the same story.
Sensors, actuators, controllers, networks, graphics, trends, and alarms all have to agree with what the HVAC equipment is actually doing. That end-to-end visibility is what turns building automation into a practical operating tool.
ABB Cylon platform
ABB Cylon technologies used across commercial building automation.
ABB Cylon systems can combine supervisory control, BACnet field controllers, engineering tools, IP controllers, and sensing technologies. The exact architecture depends on the existing building, controller generation, software, licensing, integration requirements, and project scope.
ASPECT®
Web-based supervisory building control for graphics, schedules, trends, alarms, and connected building data.
INTEGRA™
ABB Cylon supervisory building-management technology based on the Niagara Framework® for integrated building systems.
BACnet® CB Line
Programmable BACnet controllers for plant, airside, terminal, and equipment-level HVAC control applications.
CBX / CBXi
Flexible controller and I/O platforms used in scalable BACnet building-control architectures and integration applications.
FLXeon
BACnet/IP controller technology designed to use modern IP infrastructure for building control and monitoring.
CXproᴴᴰ
ABB Cylon engineering software for configuring, programming, testing, commissioning, and maintaining CB Line controllers.
Existing system? Product generation and compatibility matter. We verify the installed controller families, network, supervisory platform, licensing, field devices, and available migration path before recommending integration or replacement.
BAS troubleshooting guide
Start with the symptom. Verify the shortest path to the cause.
Controls problems can look mechanical, and mechanical problems can look like controls. Select the condition closest to what the building is experiencing to see the first checks that usually matter.
Comfort complaint: prove whether the zone, airside system, controls, or equipment is responsible.
Do not begin by rewriting a sequence. Correlate the complaint to zone temperature, discharge-air condition, airflow, damper/valve command and feedback, occupancy, equipment capacity, and actual field operation.
Alarm flood: separate the first cause from the downstream noise.
Alarm quantity is not alarm quality. Identify the initiating fault, time sequence, communications health, sensor plausibility, safeties, command/status mismatches, and whether alarm delays or priorities match the operating risk.
Runtime or schedule problem: check occupancy logic before chasing efficiency.
Unexpected operation may come from schedule hierarchy, optimum start, overrides, demand logic, freeze protection, after-hours requests, unoccupied setpoints, or a mechanical system that cannot satisfy load within the intended window.
Legacy BAS: preserve what is serviceable and replace what creates operational risk.
Inventory the front end, controller families, network segments, field devices, graphics, alarms, trends, drawings, licensing, owner standards, cybersecurity constraints, and shutdown limits before choosing full replacement.
Modernization strategy
Use ABB Cylon where it adds value. Preserve existing controls where they still make sense.
Not every building needs a full controls replacement. The right path may be a new ABB Cylon system, selective integration, service of the existing BAS, or a phased migration based on equipment condition, owner standards, budget, and shutdown limits.
Build around ABB Cylon.
A strong fit for new controls work and modernization when the owner wants an open, supportable platform with a clean long-term service path.
- Controllers and I/O selected to the equipment
- Graphics, trends, alarms, schedules
- Startup, TAB/Cx coordination, training
Keep a stable BAS productive.
If the existing controls are serviceable, targeted repairs, better trends, alarm cleanup, or sequence corrections may deliver more value than replacement.
- Fix field devices and sequences
- Improve trends and alarm usability
- Preserve owner investment where practical
Integrate where it helps operations.
Mixed-platform buildings can often be improved through selective integration, clear point mapping, and a usable operator view.
- Confirm protocols and licenses
- Define command versus monitor-only points
- Document ownership of each layer
Phase high-risk legacy systems.
When obsolete controls create operational risk, migration can be phased by building area, equipment group, or capital cycle to reduce disruption.
- Temporary coexistence strategy
- Rollback and shutdown planning
- Post-turnover trend verification
Mechanical + controls
Better controls start with a correct picture of the mechanical system.
C.E. Mechanical evaluates the BAS and the HVAC equipment it controls in the same service and retrofit conversation—helping separate programming issues from sensor, actuator, airflow, hydronic, equipment, and commissioning problems.
RTUs, AHUs, DOAS, VAV, economizers, VFDs.
Verify sensor accuracy, damper position, fan proof, airflow, static pressure, discharge-air control, safeties, economizer logic, schedules, and the actual equipment response.
Chillers, boilers, towers, pumps, valves, resets.
Trend temperatures and commands, verify waterflow and ΔT, confirm valve and VFD response, respect OEM safeties, and stage equipment around real plant behavior rather than graphics alone.
What we deliver
Controls that operators can understand, service, and trust.
A successful BAS project should leave the owner with verified sequences, useful graphics, meaningful trends and alarms, maintainable field devices, clear documentation, and a support path after turnover.
Design + controls scope
Sequences, points, controller selection, field devices, network architecture, control drawings, retrofit boundaries, and equipment coordination.
Install + programming
Panels, controllers, sensors, actuators, wiring coordination, programming, graphics, schedules, alarms, trends, and integration.
Startup + commissioning support
Point-to-point checks, command/feedback verification, sequence testing, TAB coordination, trend review, alarm validation, and correction lists.
Service + optimization
Diagnostics, sensor/actuator issues, network concerns, overrides, runtime review, recommissioning, phased upgrades, training, and documentation.
Existing BAS support
ABB Cylon is our preferred platform. We also support the systems already in your building.
Many facilities operate Siemens, Tridium Niagara, Honeywell, Johnson Controls, legacy Cylon, or mixed controls environments. We can troubleshoot, coordinate, integrate, and plan migrations where practical—without forcing unnecessary replacement.
