RE: [EnergyPlus_Support] availabilityManager:High temperaturTurnoff





This is why you must not change names and create different names of the objects.
 
"HW pump" is not the same as "pump" to me.  I do not associate 3 and 4 with the spread sheet as they are only for two other variables.
 
HW pump on and boiler off is a valid state, because the pump is not controlled by the boiler.
 
The pump is on the supply side water loop, the boiler fire is on the heating tank source side, and is not in the water loop.  Your statement on EPlus is not correct.

   thanks for looking that
The data looked normal.
 
You should have taken the temperature values at the same time.
  yes i take it but in the excel file that i send you there is nt,
You did not record the DHW pump on the spread sheet.
i  recorded  DHW pump , but in this file that i send you it is only HW pump
 
HW pump off, boiler off not listed below,
i wrote wrong in number 3, sorry , it must be HW pump off ,boiler off   there is on the spread sheet.
 in my energyplus result i dont see number 4 case (HW pump on and boiler off ) i dont undrestand why?

 ) Hw pump off but boiler on   (DHW is being heated)
2)Hw pump on and boiler on  (Normal )
3)HW pump 0ff but boiler on  (HW below set point, DHW not in use)
4)HW pump on and boiler off  (Tank is hot enough for a while)  i dont this  case result ( HW pump on and boiler off ) in my energyplus result ,

This is an indication that you did not plan the experiment well, and do not record the actual condition on site.
 
Instead of 0 and 1's on the spread sheet, you should combined the states and then list the meaning of each state.  Two pumps and a boiler fire should give you 8 states.
 yes you are right i have 8 states, but in the excel file that i sent you , there is only the result of HW pump and boiler 
Some states may not be possible, and then your should try to explain them.

please see the file that i attached :this is the real experiment data that i measured :
 
it shows some times all of below
1) Hw pump off but boiler on   (DHW is being heated)
2)Hw pump on and boiler on  (Normal )
3)pump 0ff but boiler on  (HW below set point, DHW not in use)
4)pump on and boiler off  (Tank is hot enough for a while)
