The TIDA-00838 reference design implements a heat cost allocator system following the EN834 standard with the “two-sensor measurement method". The solution achieves better than 0.5 degrees Celsius accuracy across a range of +20 to +85°C. Two analog temperature sensors are available as matched pairs to eliminate the need for calibration during manufacturing and lowering OEM system cost. Wireless MCU offers wM-Bus support for S-, T- and C-modes (Meter device) at 868MHz and controls the two temperature sensors.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
