Controllers BAScontrol Unitary Controllers
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.

BAScontrol22D
The BAScontrol22D has the same capabilities as the BAScontrol22C while offering more application memory space. Like the BAScontrol22C, the BAScontrol22D is a 22-point unitary controller which supports BACnet/IP and Sedona using a 2-port Ethernet switch connection. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 6 relay outputs. The unit has 48 web components which link Sedona wiresheet readable/writeable data to web pages, and 24 virtual points which link Sedona wiresheet readable/writeable data to a BACnet client.
BAScontrol22S
In addition to one BACnet/IP Ethernet port, the BAScontrol22S has one BACnet MS/TP serial port for added flexibility at the job site. BACnet client/server operation is possible over IP or MS/TP. Sedona programming and archiving is accomplished over IP. Like the other models, the controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 6 relay outputs. The unit has 48 web components which link Sedona wire sheet readable/writeable data to web pages, and 24 virtual points which link Sedona wire sheet readable/writeable data to a BACnet client.
Legacy Models
BAScontrol20
The BAScontrol20 is a 20-point unitary controller which supports BACnet/IP and Sedona using a single Ethernet connection. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and either four relay outputs or four triac outputs for floating controllers. The unit has 48 web components which link Sedona wiresheet readable/writeable data to web pages, and 24 virtual points which link Sedona wiresheet readable/writeable data to a BACnet client.
BAScontrol22
The BAScontrol22 is a 22-point unitary controller which supports BACnet/IP and Sedona using a 2-port Ethernet switch connection. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 6 relay outputs. The unit has 48 web components which link Sedona wiresheet readable/writeable data to web pages, and 24 virtual points which link Sedona wiresheet readable/writeable data to a BACnet client.
BAScontrol22C
The BAScontrol22C is a BACnet/IP server that also has BACnet/IP client capability allowing the user to read and/or write points served up by devices on the BACnet internetwork. Like the BAScontrol22, the BAScontrol22C is a 22-point unitary controller which supports BACnet/IP and Sedona using a 2-port Ethernet switch connection. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs and 6 relay outputs. The unit has 48 web components which link Sedona wiresheet readable/writeable data to web pages, and 24 virtual points which link Sedona wiresheet readable/writeable data to a BACnet client.
