<p>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.<br>
</p>
<p>kind regards,</p>

<div>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.</div>
<div>"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)."</div>
<div>I would like to have your help. Thanks.</div>
