I'm trying to model different thermostat control logics for an AirLoopHVAC:UnitaryHeatPump:AirToAir:Multispeed with DX coils. I'm able to institute deadbands by changing component availabilities using EMS, but now I would like to control the speed, speed ratio, and cycling ratio. However, I do not see any EMS actuators for speed or the speed and cycling ratios in the EMS Application Guide. Any suggestions on how I can accomplish this? Thanks.

I don't see any EMS actuators for Multispeed coils. Only for single-speed DX coils. You would have to modify the source code or request these actuators be added via the UserVoice suggestion web site at

Thank you. I wasn't aware of the suggestion site.
