The installation of Direct Digital Control (DDC) systems follows a structured process to ensure efficiency and reliability in commercial.

HVAC systems. Our installation process includes:

  1. Pre-Installation Planning – We review project specifications, electrical schematics, and control diagrams to ensure proper integration with the building’s HVAC system. Coordination with general contractors and engineers is essential.

  2. Mounting and Wiring – Our team installs the DDC controllers in designated control panels or enclosures, ensuring proper positioning for accessibility and ventilation. We then connect field devices (sensors, actuators, relays) to the controller using low-voltage wiring, following best practices for cable management.

  3. Power and Network Configuration – Controllers are wired to power sources and connected to the BACnet or Modbus network, ensuring seamless communication with the Building Automation System (BAS).

  4. Sensor & Equipment Integration – We integrate temperature, humidity, pressure, and occupancy sensors, along with actuators, dampers, and variable frequency drives (VFDs), configuring inputs and outputs as required.

  5. Programming and Commissioning – Our technicians will maintenance & calibrate sensors, and test system responsiveness.

  6. Final Testing and Client Handover – We perform a functional performance test (FPT), verify alarms and trend logs, and provide training for facility managers before finalizing the installation.

"Our goal is to ensure seamless automation, energy efficiency, and long-term reliability in every DDC system we install."

"Our company specializes in seamless Building Automation System (BAS) integration, ensuring that all HVAC components communicate efficiently for optimized performance, energy savings, and ease of operation."

Our BAS Integration Process:

  1. System Design & Coordination – We collaborate with general contractors, engineers, and facility managers to install a custom BAS solution tailored to the building’s HVAC infrastructure and operational needs.

  2. Controller & Device Installation – Our team installs DDC controllers, sensors, actuators, and other field devices, ensuring proper wiring and connectivity for real-time data collection and control.

  3. Network Communication Setup – We integrate controllers into the building’s BACnet, Modbus, or LonWorks network, ensuring interoperability with third-party equipment. Secure IP or MSTP configurations are implemented for reliable data exchange.

  4. Testing & Commissioning – A comprehensive physical point-to-point check is conducted to validate sensor readings, actuator movement, and network communication. Functional performance testing (FPT) ensures system reliability before full deployment.

  5. User Training & Handover – We provide hands-on training for facility personnel, ensuring they can monitor, control, and troubleshoot the system through the BAS workstation or remote access.

"Our BAS integration enhances building efficiency, reduces operational costs, and ensures long-term HVAC system performance."
