BACnet service tool gives user field access to controller point information. The tool runs on a Windows Pocket PC or laptop and automatically discovers and edits BACnet devices from third parties as well as the manufacturer’s lines of controllers. It provides multiple displays of the entire BACnet system, including objects within the device, and detailed views of the BACnet properties of selected objects. Technicians can edit and change values, set descriptions and more. For more about Roam I02 from TAC, click here .

Control device provides full capacity modulation for all sizes of direct-expansion air conditioning systems that use R-410A non-ozone-depleting hydrofluorocarbon refrigerant. The control continuously and automatically matches AC system capacity/output to changing load conditions. It is claimed to dramatically improve humidity control without overcooling the space and eliminate common maintenance problems associated with excess system capacity such as coil icing, liquid slugging, and excessive compressor cycling.

Fan-coil thermostat is low-voltage Lontalk communicating device that is said to offer reduced installation cost and delivery time by reducing wiring. Units are pre-programmed with six onboard sequences of operation. The device is suitable for two- and four-pipe applications with or without local reheat.

Room pressurization control is said by its manufacturer to be suited to VAV controller applications where stable directional airflow into or out of the space is critical. The device also performs occupancy and HVAC emergency mode control either locally or through network commands from the BAS. For more about Traccel by Phoenix Controls, click here .
