Thanks Archmage, I tried both of your suggestions,

  1. The first suggestion works but it is required to keep the thermostat to a high temperature and remove the bypass pipe.

  2. I put a loadprofile:plant after the baseboard with zero load but controlling that object flow rate can not overwrite the base board flow rate.

Dear Sir/Madam,

I am trying to overwrite the existing control of baseboard heater in EnergyPlus with an EMS program. There is no actuator for control of baseboard mass flow and I just defined an actuator on input mass flow node of baseboard and wrote a program to set this value for every time step. However, when i run the simulation, this control does not apply and the baseboard convector still operates with existing control algorithm in the energyPlus. Could you give me some hints on how to fix this problem. Any option beside modifying the EnergyPlus source codes?

Regards, Esmail

I was trying to modify an existing IDF file to include a certain zones within the file. I am keep getting the below error for a certain air loops. All the details are the same for these air loops and others. Could anybody give me a hint on how to fix this problem.
