Are you dividing your flow by a simple fraction (80% goes to the
boiler and 20% goes to recirculation for example) or is the Type11
set up so that it tries to maintain a set point temperature like a
tempering valve might do? The error that you are getting is one
that comes when Type11 is used as a tempering valve but can't
achieve the set point because both of the inlet temperatures are
already above the set point. A little additional explanation might
help me find a suggestion for how to work around the issue.
kind regards,

Good morning,simulating the operation of a condensing boiler with a power of 20kW and a setpoint temperature of 50 degrees; I get the following error, which I report later, in type 11b. With this type I divide my flow rate into the boiler flow rate and the recirculation flow rate."The inlet temperature and the heat source temperature have simultaneously exceeded the set point temperature. Gamma has been set to 0 (Mode 4) or 1 (Mode 5)."I would like to have your help. Thanks.
