Direct LV works across Automated Logic (ALC), Trane, Johnson Controls (JCI), and other major BAS/DDC platforms—from low-voltage field wiring and controllers to BACnet networks and the building automation front end.
Professional DDC installation, startup, troubleshooting, and commissioning for commercial HVAC systems. Direct LV works across Automated Logic (ALC), Trane, Johnson Controls (JCI), and other major BAS/DDC platforms—from low-voltage field wiring and controllers to BACnet networks and the building automation front end.
Commercial HVAC only performs as intended when the controls sequence, field devices, wiring, and network work together. We install and service the complete DDC path—from field sensors and actuators to the controller, BACnet network, and building automation front end—working from drawings, point lists, and sequences of operation on new construction, tenant improvements, and existing-building upgrades.
Whether the platform is Automated Logic (ALC), Trane, Johnson Controls (JCI), or another major BAS/DDC system, the goal is the same: accurate inputs, reliable outputs, and documentation you can trust.
Installation, routing, labeling, and termination of low-voltage control wiring for field devices, equipment interfaces, and control panels.
DDC controller mounting, termination, panel assembly, power checks, relay interfaces, terminal identification, and panel cleanup.
Sensors, thermostats, actuators, control valves, dampers, VFD interfaces, safeties, and other field devices connected and checked against the intended sequence.
BACnet communication wiring, controller addressing support, network troubleshooting, and integration work for compatible building automation systems.
Every input and output is traced from the field device through the DDC controller to confirm point identity, signal accuracy, command response, and final equipment action.
Functional testing against drawings and sequences of operation, issue documentation, corrections within scope, and verification before handoff.
We review drawings, point lists, sequences of operation, equipment, platform, access needs, and the field conditions that affect installation.
Controllers, panels, field devices, low-voltage wiring, and equipment interfaces are installed and terminated to the approved project requirements.
We verify point-to-point operation, inputs, outputs, communication, and equipment response while coordinating with the project team as needed.
The completed work is functionally tested against the sequence of operation, deficiencies are documented, and verified control points are handed off clearly.
Direct LV has experience working across Automated Logic (ALC), Trane, Johnson Controls (JCI), and other major BAS/DDC systems. Before work begins, we verify the specific platform, controller family, access, protocol, and project scope.
