after testing the Comet valve I have know purchase the Danfoss LC-13.
Installation etc is no Problem, but it does not react at all. I tried to controll it via a virtual Thermostat and via a rule, but none of them seem to work. Also by Manual Change it aways switches back to 4°C ... not very comfortable.
I am sure here are many users of this valve. Could you please give me your solution of this "problem".
