I do not understand your question or the purpose of the moving of the pump position.
In your PDF diagram, the pump is in the orage coloured pipe, lower temperature return pipe. This is the position in the SVG diagram, and is the recommended branch ordering.
It is possible to move the pump to the demand side inlet, but you should ask the support group, if the simulation fails.
The SVG diagram looks fine, although it is not the usual view, which begins with a pump without a by-pass path.
use bypass with pump , in example files of energyplus i see it use boiler branch with bypass , but in my idef i use pump branch with bypass branch .
in summer or some times of the year that produces the pressure difference due to temperature difference ,(natural circulating with out need pump )
we use bypass mode and pump is out of the work , how can i show this in simulation in energyplus ?( i want to say use bypass branch instead of pump in summer )

WaterHeater:Mixed,
Indirect Water Heater, !- Name
AUTOSIZE, !- Tank Volume {m3}
water heater Setpoint Temperature Schedule, !- Setpoint Temperature Schedule Name
field: Setpoint Temperature , determines when heater of the water heater will be on and off ,is that right?
but in ALL OBJECTS IN CLASS: BOILER:HOTWATER, there is no Setpoint Temperature Schedule field to determines when burner of boiler will be on and off , how can i control the burner of boiler?does setpoint temperature in pLant loop(hot water plant loop) controls burner of boiler ?
the setpoint temperature for plant loops it means it controls the whole plant (pump , boiler )?
