About Alerton Building Automation Controllers

A building management system of this type is a tiered network. At the bottom sit application-specific controllers dedicated to one piece of equipment, a VAV box, a fan coil unit or a heat pump, with a fixed input and output count matched to that equipment and a configuration rather than a full custom program. Above them sit programmable field controllers with a larger and more varied I/O count that run air handling units, chiller plant sequences and central plant logic, and that also act as a routing point between the field bus and the building-level network. All of it communicates over BACnet, either over the MS/TP twisted-pair field bus or over IP on the building network, and the two are bridged by a router or a controller acting as one. The practical consequences for a replacement are that input and output counts and types must match the wiring already in place, that the controller's device instance and MS/TP address have to be set to the values the system expects, and that the application program or configuration has to be reloaded from the site database.

Alerton Building Automation Controllers in Saudi Arabia

Building management is a large and growing segment in the Kingdom because cooling dominates energy use in almost every occupied building. Controllers of this type run air handling units, chilled water plant, VAV terminal boxes and fan coil units in office towers, hospitals, hotels, universities, airports, shopping centres and government buildings in Riyadh, Jeddah, Dammam and the new developments at NEOM and along the Red Sea coast. Because the cooling load runs at or near design condition for much of the year, control quality translates directly into energy cost, and retrofit projects driven by efficiency programmes are a steady source of controller replacement. Local supply for control transformers and field devices is derived from a 380/400 V 60 Hz system. Ceiling voids and plant rooms run hot, which makes controller ambient rating and enclosure ventilation worth checking rather than assuming.

Ordering and lead time

Quote the Alerton model number as printed on the controller label, for example VLC-1600 or VAVIH-SD, because the model fixes the input and output count and type. When replacing a controller, record the existing device instance, the MS/TP address and baud rate, and the terminal assignments before removal, since the replacement must be addressed and wired identically and the application program reloaded from the site database. State whether the unit sits on an MS/TP field bus or on the IP network. Give the control transformer voltage available at the equipment. If sensors or actuators are required alongside the controller, list them with their signal type, such as resistance temperature input or 0 to 10 V analogue output. Items are sourced to order with a typical lead time of three weeks and delivered duty-paid to site.
