Overview
The VFG54+ measures the temperature of cold or hot water on pipes and other curved surfaces. The spring-loaded brass contact sensor gives a fast response and can be fitted along the pipe or sideways. It has a BACnet MS/TP interface and, as well, active 0 to 10 V or 0 to 5 V outputs. Settings are made with the USEapp, uConfig, jumpers and DIP switches. The LCD version has a colour changing display with a traffic light function. Wiring is tool-free in a USE-M enclosure with a hinged cover.
