Contemporary Controls’ Control Network Newsletter: New PI-Based Products to Celebrate Pi Day

New PI-Based Products to Celebrate Pi Day

In honor of Pi Day, we’re celebrating the Raspberry Pi, which was created by the Raspberry Pi Foundation as a way to make computers more accessible to people all over the world. The Foundation provides low-cost, high-performance computers so more people are “capable of understanding and shaping our increasingly digital world, able to solve the problems that matter to them, and equipped for the jobs of the future,” (Source:

Contemporary Controls strongly supports the vision of using open hardware and software to make technology more accessible to everyone. As part of our vision for open control, we’ve created products that leverage the Raspberry Pi. We chose the Raspberry Pi because it is a powerful embedded platform, it is easily accessible, and it is the micro PC with the largest community which provides support in the form of custom applications, software tricks and neat “hacks”. Given that the community already has a lot of diverse applications for the Raspberry Pi, we wanted our products to offer new capabilities.

Control Without Restrictions

The BASpi I/O board turns your Raspberry Pi into a BACnet-networked, Sedona-programmable controller with 6 Universal Inputs and 6 Relay Outputs. The BASpi hat provides enhanced hardware circuitry, web-based configuration, and free graphical programming software for control applications. We wanted to truly enhance the capabilities of the Raspberry Pi3. We also wanted to keep both the hardware and software open, so we designed our BASpi hat so it can be run in conjunction with other applications on the Raspberry Pi.

Combined with our BASpi hardware and software tools enhancements, the already powerful Raspberry Pi3 turns into an extremely capable control device with web based configuration, universal IO, and industry standard data communication and control protocol – BACnet.

We’ve created two versions of the BASpi. One is just our BASpi I/O board for those people who already have a Raspberry Pi and are experienced with programming it. The other is the entire system, which includes the Raspberry Pi 3 board, our BASpi I/O board, an industrial grade μSD card with pre-written image, international power supply, and an enclosure case.

Open Control Meets Micro PC

Our soon-to-be released BASpi BACnet Client Controller turns an already powerful micro PC, Raspberry Pi, into a BACnet client and open Sedona controller. It serves as a mini-supervisor to BACnet/IP server devices over Ethernet or Wi-Fi and BACnet MS/TP devices over EIA-485. Using custom Sedona network variable components, the BCC can initiate read/write commands from its Sedona wire sheet to BACnet/IP or BACnet MS/TP server points on remote devices. Server points need not be Sedona compliant – just BACnet compliant. Any BACnet remote I/O such as Contemporary Controls’ Cube I/O can be made into a freely-programmable controller with the addition of the BCC. More information about the BASpi BCC coming soon.

We aren’t done yet — stay tuned for more products based on the Raspberry Pi in the near future.

New BAScontrol22C with BACnet Client Capability
The new BAScontrol22C supports BACnet client capability in addition to the existing server functionality. Most BACnet devices are servers, which do not initiate requests to other BACnet devices other than an initial “I-Am” broadcast when first joining the network. BACnet clients (like the BAScontrol22C) can initiate requests and expect BACnet servers to respond to requests as data is exchanged.
BACnet-Complaint Thermostat Ensures Effortless Integration
Contemporary Controls continues its mission of “Building on BACnet” by introducing the BASstat series of BACnet-compliant communicating thermostats that are BTL Listed to ensure effortless integration into BACnet MS/TP (EIA-485) networks.BASstat thermostats are suited for single or multi-stage heating, cooling and ventilation binary output control applications such as RTU or AHU.
Training and Education with Contemporary Controls Networking and Control Equipment
Contemporary Controls is committed to helping educate the newest members of the HVACR industry in best practices for building automation by providing education and training support. Most recently, Contemporary Controls participated in the 2019 National HVACR Educators and Trainers Conference March 3-5, 2019 in Las Vegas, Nevada.
