[TRNSYS-users] PID Type 23 # of Warnings Exceeded

[Devin Rohan <drohan@purdue.edu>]

I have a PID controller (type 23) controlling the operative temperature of a room modeled in Type 56 through the an active layer floor heating system, where I control the water supply temperature and have a constant mass flow rate.  I tried to base it of the floor heating example TRNSYS provides in the feedback control example folder.  When I run the simulation, I get an error saying that the number of warnings allowed for a simulation has been exceeded.  How can I fix this?  Here is how I have my controller connected to the multizone building model:

 Equation Editor                    PID                        Type 56

T_operative_set=23  ---------> Setpoint

                                      Control Signal   --------->   T_supply

                                Controlled Variable  <--------    TOPLW  (long wave operative temperature)

Thanks for any help
