T4M versus T4R
Posted: Thu Apr 25, 2019 7:50 pm
Hi, I have used a T4M (directly wired, opentherm modulating) very succesfully with Opentherm on an Intergas combi. Just had to enable the Room Compensation parameter on the T4M.
I'm looking getting a T4R (wireless) for use with another Intergas combi install. Honeywell say it is Opentherm compatible but there is no info on the Opentherm parameters.
I phoned Honeywell tech support... they didnt know
They said phone Intergas. And then Intergas said phone Honeywell 
So... Can a T4R modulate the boiler flow temp via Opentherm?
