Hi, I have installed Baxi Nuvola 3 Comfort with Nest 3rd gen thermostat
over OpenTherm. The heating works, however there is no hot water. The
boiler doesn't come on when hot tap is opened. Any ideas?Thank you
The problem is the boiler doesn't have any other controls than the
thermostat which you can install on the wall or on the boiler and
configure it as such. Then I can control the hot water. However both
cases it occupies OpenTherm terminals so there i...
I performed the install. I wired boiler's M2 pins 1, 2 (wires for
proprietary thermostat, which should communicate over OpenTherm) with
HeatLink OT1, OT2.
It occurred right after I installed NEST. I installed it on 29th
November. The hot water doesn't work since so I had to revert to
original Baxi thermostat.
The configuration is Combi bolier of course. Tried also System boiler
with no hot water control, but none of them works. When I connect the
original Baxi thermostat back, everything works as expected
