[esp-r] 4 stage heater

Fri Mar 8 13:58:57 GMT 2013

Dear list,

I am modelling an HVAC plant at a component level. The air handling unit includes a 4-stage heater, which can operate in one of these 4 stages: 20kW 40kW 60kW and 80kW. I have managed to control the heater with a PID controller however I have not found a way to force it to take only these 4 discrete values. Are there any techniques integrated in Esp-r in order to model/control such a component?

Kind regards,
