Thermostatic device

Anything >=50% and I start the boiler.

Interesting approach! Could you describe it in some more detail in the Recipes forum, so others can repeat this method ?
Thanks

I would, but after some testing... I've decided it's no where near as good as operating in position control mode.

If they let users config the PID parameters, that'd probably help.

I don't think StellaZ does have PID. Some Stella F models have, but those aren't z-wave

Yea I appreciate that, but whatever constants etc it uses to control the valve position relative to temperature error are way off.

It's a shame, because I quite like self regulation mode.... its just not good enough as it stands.
