The fitting of Simplex is precisely and quietly, the possibility to rotate the connectors is smart. So it can be used with thermostatic left or right. However, one must note the 2.5 cm offset at the terminals and the cover fits naturally only in the intended orientation. The return can be shut off, the flow can be adjusted. A manual is included.
Although the thermostatic head has a nice design, but the temperature nearby because it deregulates too fast. For remeasured 21 degrees I need to set 4-5. On the other hand, the price is quite cheap already own for fitting.
