• Open‑protocol controls with BACnet/IP, BACnet MS/TP, and Modbus gateways
• Custom graphics, dashboards, and role‑based remote access for teams and vendors
• Scheduling, trend logs, and alarms for proactive facility management
• Indoor air quality strategies: CO2/DCV, filtration, humidity, and ventilation balance
• Energy optimization: economizer logic, heat recovery, demand limiting, and load shedding
• Sequence of Operations (SOO) development and documentation for future serviceability
• Retrofit of legacy controls and phased migration to minimize downtime
• Commissioning, functional testing, training, and turnover packages

Daikin Integration & Open Protocols

We integrate Daikin VRV/VRF, chillers, and rooftop units into your Building Management System using open standards for long‑term flexibility. Whether your site requires BACnet/IP, BACnet MS/TP, or Modbus gateways, we engineer reliable communication paths, normalize points, and implement sequences that protect comfort and equipment health.

• VRV/VRF point mapping, mode management, and capacity tracking
• Chiller plant optimization, staging, and condenser water strategies
• Rooftop unit economizer logic, free cooling, and DCV for IAQ
• Alarm rationalization to reduce nuisance alerts and speed response
• Trend frameworks for analytics, root‑cause, and continuous commissioning

Note: We routinely work with Daikin equipment in commercial BMS environments. Our team’s factory training is with Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier.

Industries & Building Types We Serve in Fullerton

• Medical and dental clinics, labs, and wellness centers focused on IAQ
• Education: K‑12, higher‑ed, and private academies
• Office, creative space, and Class‑A commercial
• Retail, restaurants, and mixed‑use developments
• Industrial flex, light manufacturing, and warehouses
• Multifamily common areas and amenity spaces

Our Process

• Assessment & Data Pull: Site walk, drawings review, points list, and existing controls audit. We benchmark comfort, IAQ, and energy baselines.
• Engineering & SOO: Controls architecture, network topology, safety interlocks, and Sequence of Operations tuned to your goals.
• Integration & Graphics: Gateways, controllers, naming standards, dashboards, and alarm strategies that your team can trust.
• Commissioning & Training: Functional testing, trend validation, documentation, and hands‑on training for facilities staff.
• Optimization & Support: Post‑turnover tuning, analytics, and preventive maintenance options to keep performance locked in.

Common Issues We Solve

• Hot/cold complaints and unstable setpoints across zones
• High energy bills from poor sequences or disabled economizers
• Frequent alarms, short cycling, or conflicting modes in VRV/VRF
• Insufficient fresh air, high CO2, or humidity swings affecting IAQ
• Legacy BMS with vendor lock‑in and limited visibility
• Incomplete documentation and unclear control logic

Service Area

We are local to Fullerton and serve Orange County and the greater Los Angeles market, including Los Angeles County, Ventura County, and Western Riverside County. Nearby Fullerton cities we often support include Anaheim, Brea, Buena Park, Placentia, and La Habra—ideal for portfolios with multiple sites.

Health‑Focused by Design

Healthy indoor air is our core mission. We apply engineering best practices—ventilation verification, filtration upgrades, CO2‑based DCV, and humidity control—to improve occupant well‑being while managing energy spend. Your BMS becomes the hub for measurable IAQ with actionable trends and alarms.

Documentation & Training

Every project includes as‑built drawings, point lists, SOO documents, alarm matrices, and training so your facilities team can operate with confidence. Clear naming conventions and graphic standards reduce troubleshooting time and future service costs.
