Set Max CH setpoint boundaries (MsgID=49)

Post by pengemetal »

Hi,

How can I set Max CH setpoint boundaries (MsgID=49)? I Have a Viessmann Vitodens 100W with OTGW and on-of thermostat, I can't set max setpoint higher than 39 C, because the boundaries are 39 20. THX

Other people have encountered this bug of the Viessmann Vitodens boiler. See this topic for more details and a procedure for how to reset the boundaries.
