Your English is very good. I know what you are saying. The problems is that you were not looking at a part and describe it probably.
but in real system in DHW tank i dont have any thermostat
The secondwater heater for the DHW, you did not show. It has its own thermastat and control switch build-in.
what do you mean second water heater?? in my building there is only one tank !!!
The electric heater in your automatic kettle you know. How does it work?
yes i know!!
You have a HW furnace, or tank, or boiler tank.
You also have DHW water tank. Therefore there are two tanks.
In one of your email, you said that there is back up heater for the domestic hot water tank..
no there is no heater for domostic hot water , there is only one heater that this is boiler

Subject: [EnergyPlus_Support] availabilityManager:High temperaturTurnoff
Dear memebers ,
ref : Document :EngineeringRefrence.pdf -983
"High temperature turn off :
The input object availabilityManager:High temperaturTurnoff is used to turn off a central air system or a plant loop if a sensed node temperature exceeds a temperature limit."
i want to know availabilityManager:High temperaturTurnoff , turn off the plant loop or just the turn off the component ?
for example : i set field :Sensor Node name : at the outlet of boiler .. in this plant loop there is pump and boiler as a component.
then availabilityManager:High temperaturTurnoff turn off boiler or plant loop ?if it turn off the plant loop it means it turned off pump too?
thanks
