Hi Guys, The new firmare is aivaliable for our FGT-001 heating valves. The version is 4.3. Im updating my 6 valves. Each valved take more than 20 minutes to complete the procedure. Cross the finger and share the experience....    If you are running HC FW older than 1.462 (beta) do not perform remove/reset/include after update TRV's FW.  (Thanks to adyboss for the suggestion)
