The Tunze Wavecontroller 7092 is a refreshed module from Tunze which combines the features of the Singlecontroller 7091 and the Wavecontroller 6091. Mark Callahan has produced an excellent and thorough video on the 7092 Wavecontroller, and especially how it is an improvement over the dial ‘hweel’ of the old 6091.  In addition to a more streamlined control of your Tunze pumps, the Wavecontroller 7092 has an interesting Auto-Adjust function which incrementally adjusts the length of pump pulses by 1/1000th of a second to help you find that harmonic wave. The Wavecontroller 7092 first came to light at InterZoo back in May but it will become available this month in the US for around $75.
