Subject: [TRNSYS-users] Fwd: issue with active layer

Hello,
I am trying to model a multi-floor building with Ceiling heating. The temperature of each floor is controlled by a thermostat, that closes inlet valve when indoor temperature reaches a specific level. But I have a problem to model this control, because as you see in the picture below there is a "min. allowed inlet mass flowrate" . So if the valve closes the inlet water I receive an error that flowrate is below the level.

  *   How can I design it in a way that the inlet flowrate can be zero sometimes?
  *   Also my other question is about the surfaces section also shown in the picture below. I do not know why two CEILINGs appeared there, and I cannot delete them.
Thank you
