I have a question regarding the use of the External Interface and the control of a electric baseboard. I am currently using the ZoneHVAC:Baseboard:Convective:Electric object and was wondering if it is possible to change the heating design capacity during the simulation. I would like to change the capacity depending on the outside and zone temperature. You could say that I'm trying to do what the thermostat object in EnergyPlus already does automatically. Is it possible to do something like that by using the ExternalInterface:Actuator object? I checked External Interface Application Guide but the examples there are very different and I wasn't able to find any example idfs including ExternalInterface objects. Any help or tip is appreciated.

I actually need to do this now. I need to design a controller to vary the wattage of the baseboard convective electric. How did you get on with it?

I wasn't able to find a way to do this so I switched to hot water systems. I checked the Actuator objects available and it doesn't seem like that there is a straightforward way to do it.

You can do it via EMS through Sensors getting temperatures, and an Actuator to control actual cooling capacity.

Place an Output:EnergyManagementSystem object in your IDF before running a trial simulations in order to get the EDD file. In EDD file you can find Sensors/Actuators you are looking for to use them in an EMS Program

Here the guide to use EMS

You could instead use the ZoneBaseboard:OutdoorTemperatureControlled object which has an actuator of type "Power Level".
