Manual is, a bit small, but writing is legible.
There are 3 adapter, but I have found that not a single adapter to the large diameter of the electronic valve covers to my heart valves, so I went in search for adapters to reduce the diameter.
I find anything: Xavax Adapter for radiator valves with M28 x 1.5 mm connection thread (reduction of M30 to M28), the adapter will cost 5.99 EUR
The product description of the electronic valves is correct, the fit to the diameter of M30. Of course, only I did not know what diameter had my heart and thanks to Google, I found it.
With whom the electronic valve does not work, should check whether his radiators are vented, I immediately a valve for automatic venting dazubestellt, so I have to do anything:
Enzo Rodi 782 310 Automatic air vent for radiators, set of 2
Please note: ordered sure the vent valve made of metal, there are other (cheaper), but then do not work as you'd expect.
So I'm sure that after 2 months of heating season are expected to have due to the savings in heating costs all investments :-)
