Ive followed several threads re VR33 and OpenTherm.
Im going to replace VRC430 with a Nest 3. My system is ecoTEC plus 630VU GB 306/3-5 with VR65 + VR10 NTC, VRC430 (remote install).
I also have external Temp sensor (VR 693) connected that I assume will not be seen by Nest and is now superfluous.
I just want to confirm Ive understood the install process - disconnect VRC430, Install VR33 connected to X31, new link across RT/24V 78, the 240v link 34 is already in place.
Check all is well by short / open the OpenTherm bus and check 10C / 90C targets.
Connect Nest 3 / HeatLink and verify it is seen via d.90
Set up Nest 3 with AutoLearn and True Radiant to enable boiler modulation
Am I on the right track? Anything Ive missed? Any further tips? Welcome thank you.
