I am using OS 2.4.0. I have been trying to model a DOAS unit with separate seperate unitary water to air units set to setpoint control and I have had nothing but issues. One error is that once I set it to setpoint control the electric reheat coil keeps asking for a control node which I cannot enter since it is not accessible.

** 
* Severe  ** * Coil:Heating:Electric "ELEC HTG COIL 13"
**  *   ~~~   ** * ... Missing control node for heating coil.
**  *   ~~~   ** * ... enter a control node name in the coil temperature setpoint node field for this heating coil.
**  *   ~~~   ** * ... use a Setpoint Manager to establish a setpoint at the coil temperature setpoint node.

I am not sure I am using the right setpoint managers for this approach. I really want to control to a supply air temperature and not a zone temperature. Any ideas? Here is a link to the test file I am working with: with Test Case Doas.osmlink text
