BACnet-compliant thermostats for HVAC systems

Contemporary Controls is now offersing BACnet-compliant wired or wireless communicating thermostats suitable for modulated heating, cooling, and ventilation for 4-pipe HVAC systems.

“The new thermostats are intended for modulated control of fan coil units (FCUs), which are often used on job sites because they allow the HVAC system to react to load changes within a space quickly and efficiently,” said Michał Papierz EMEA Operations Manager, Sales & Marketing at Contemporary Controls. “ By providing modulated control, the thermostats work with FCUs to provide a more consistent and comfortable environment within a building.”

The new models join Contemporary Controls’ popular BASstat Communicating Thermostat series. They are BACnet compliant to ensure seamless integration into a BACnet/IP (Wi-Fi) or BACnet MS/TP (EIA-485) networks.

The BAST-421C-B2 wired thermostat (BTL Listed) is BACnet MS/TP connected utilizing an EIA-485 serial connection. The BAST-421C-BW2 wireless thermostat is BACnet/IP connected using a wireless connection to a nearby Wi-Fi router/access point which supports IEEE 802.11b/g/n.

Both models provide modulated heating and cooling control in an attractive wall-mounted enclosure with a large LCD display. Intended for use with 4-pipe heated/chilled water FCUs, the thermostats can control 2 analog modulating water valve actuators and one binary supply fan. A large and easy to read LCD display indicates setpoint, space temperature, and current mode of operation using graphical icons.
