Rialto Commercial DDC (Direct Digital Controls) — AC PRO Integration

What is Commercial DDC—and why it matters in Rialto

Direct Digital Controls (DDC) give you precise, programmable control of your HVAC systems. Sensors, controllers, and supervisory software work together to maintain temperature, humidity, ventilation, and air quality while using the least possible energy. In busy Rialto facilities—offices, retail, warehouses, schools—DDC stabilizes comfort, proves performance with data, and automates compliance reporting.

Systems we design, integrate, and service

• Rooftop units (RTUs), split systems, and heat pumps
• VRF/VRV systems (zoning, heat recovery, advanced ventilation)
• Make‑up air units, DOAS, economizers, and energy recovery
• VAV/VVT with pressure‑independent control
• Boilers, chillers, pumps, and hydronic loops
• Demand‑controlled ventilation with CO₂/PM2.5/TVOC sensors
• Filtration and IAQ devices integrated into control strategies

AC PRO–compatible DDC integration

We design controls that integrate cleanly with AC PRO–supplied commercial HVAC equipment—new or existing—so you get unified command, trending, alarms, and dashboards. Whether it’s a retrofit overlay for legacy units or a ground‑up deployment, we align our controls with published equipment capabilities and sequences to protect performance and reliability.

Healthy air, engineered

Our mission is healthy air for healthier lives. We encode IAQ into the control logic—ventilation verification, filtration status, sensor validation, and fault detection—so you don’t just assume better air, you can prove it. Expect standards‑aligned strategies and reports your team can act on.

Compliance and standards

We design with California Title 24 requirements in mind, along with relevant ASHRAE guidelines and local permitting needs. From demand‑control ventilation to economizer fault detection, our DDC sequences and commissioning documents help streamline compliance and inspections in Rialto and neighboring jurisdictions.

Typical project workflow

• Discovery: goals, constraints, and existing system review
• Data: short‑term logging and utility analysis to size opportunities
• Design: sequences, control drawings, network topology, submittals
• Build: panel fabrication, wiring, controller programming, graphics
• Commission: point‑to‑point, functional tests, tuning, owner training
• Verify: trend reviews, M&V plan, handoff documentation
• Support: remote monitoring, planned maintenance, continuous improvement

Results you can measure

Well‑engineered DDC delivers comfort stability, lower kWh/therms, extended equipment life, fewer hot/cold calls, and faster troubleshooting. With trends and analytics, your team gains visibility to act before issues escalate—protecting uptime and budgets.
