Williams Mechanical's controls division has a wide range of experience in the building automation industry with advanced knowledge in many types of control system products.  Our controls team specializes in the ASI Controls product line and we even have a partnership with the ASI Controls team.  In addition to the ASI Controls products, we also support, service and install control products such as Tridium's Niagara, Pelican Wireless and Honeywell Controls.  We can even support the Johnson Controls products as well as their Metasys product line.

Building Automation and Energy Cost Savings

ASI Controls provides tools to implement scheduled control of building environments.  Their systems can automatically control facility energy costs using capabilities that include demand limiting, load shedding, optimum start, and Modbus for control of VFD's and other energy efficient devices.  ASI Controls Energy Management Systems (EMS) can provide facilities with automated climate control, browser based monitoring, and verifiable, persistent energy cost savings.

ASI Control system products are a great choice for many reasons.

1.  Planned obsolescence is not in ASI's vocabulary.  ASI stands by all of its products; with complete backwards compatibility, we can continue to service, add, and replace ASI devices of any age without the need to spend thousands of dollars on new software or controls to be compatible again.

2. The control products are built on extremely robust hardware with applications to control VAV Boxes, Air Handlers, Rooftop Units, Central Plants and many other HVAC devices.

3. Unsurpassed manufacturer support. ASI provides direct support from their home in Northern California to our field technicians and management.

4. Value. The hardware is well built with more on board capability than other manufacturers while remaining competitively priced.

5. The complete flexibility of BACnet, Modbus or OPC integrations.

“ASI Controls value-added resellers and system integrators have configured and installed ASI hardware and software to meet digital control requirements in thousands of commercial buildings, shopping malls, equipment shelters, and many other types of facilities worldwide. Solutions available through authorized ASI Controls resellers are primarily focused on control of heating, ventilating, air-conditioning, and lighting. Other applications include control of OEM equipment such as Chillers, VAV boxes, Boilers, Rooftop and Penthouse units, and other large equipment; integrating access control and DVR technologies into a single, unified building front end; light industrial automation including control of Yokogawa DVR PLCs using OPC; irrigation control, and many other applications.”

ASI Controls Success Story

EMS Saves Hotel $127,000

A major international hotel chain retrofitted an ASI EMS at their Anaheim location to control air distribution systems, cooling towers, and a 3,150 Ton Chiller Plant.  The ability to deliver energy savings while maintaining guest comfort led the company to do ASI EMS retrofits at their other locations.

ASI Controls Zone Dial

In addition to the great products and services ASI provides, they also offer an after hours tenant billing service called Zone Dial.

Zone Dial is an after hours tenant billing software that has a user friendly and intuitive interface.  Owners can customize the settings for the flexibility of:

• Tenants access
• The dollar amount tenants are billed per hour for an after hours request
• Billable times during the day, that are after normal business hours
• Professionally generated invoices to be sent out to the tenants for monthly after hours usage.
• The option to use either a web browser or mobile device for access.

The Niagara Framework provides open system interoperability through a powerful application framework supporting industry standard open protocols such as BACnet, LON, Modbus, OBIX and many others.

If you're asking "why is this important to me?"  The answer is simple

Flexible integration's without being bound to a single control manufacturer.

Niagara can integrate a wide range of devices to a single head end.  What's more is you can integrate multiple facilities to a single head end.  This is an ideal solution for school districts, hospital campuses, hotels and resorts, and so on.  These integration's include any open protocol such as Modbus, LON and BACnet; Niagara would be a great choice if you had a combination of any of these controls protocol brands.  In addition to your HVAC equipment you can also integrate your lighting, IP cameras and energy meters for example, without the need for several different types of equipment to buy to try and access them.
