Contemporary Controls has always supported open protocols like BACnet, but BACnet does not provide control, only a standardized method for communications. Having BACnet is not sufficient when you are locked out of a job due to a proprietary programming language, licensing restrictions, or a proprietary programming tool only available to "partners". The BAScontrol Series is Contemporary Controls' way of providing a truly open controller by having:
The BAScontrol Series of unitary controllers are ideal for general purpose applications, such as controlling fan coils, heat pumps, lead-lag pump sequences, and constant volume air-handlers and RTUs. The BAScontrollers remain popular with system integrators, mechanical OEMs, and HVAC training institutions because of their license-free open architecture and free toolset. These controllers offer simple webpage configuration, function block Sedona programming, and are freely programmable using Contemporary Controls' BAScontrol Toolset. In addition, pre-built Sedona applications with included documentation are available to speed project implementation.
Rugged design, low profile, and wide temperature operation make the series suitable for indoor or outdoor use. The units are powered from a 24VAC/VDC source. All models support BACnet/IP server operation with newer models supporting BACnet/IP client functionality as well. An MS/TP model supports BACnet client/server operation over BACnet/IP or BACnet MS/TP.
All BAScontrol unitary controllers are programmed using Sedona—a license-free function block programming language intended for implementing control schemes. The Sedona language facilitates component-oriented programming where components (deployed in kits) are assembled onto a wiresheet, configured, and then interconnected to create applications.
The BAScontrol-E36 is an Advanced Rooftop Controller which is intended for energy optimization utilizing advanced control sequences in rooftop units. The controller has the necessary computing power and input/output (I/O) point count to execute recommended advanced sequences published in ASHRAE Guideline 36-2018 High-Performance Sequences of Operation for HVAC Systems (GL-36).
