RE: [EnergyPlus_Support] Solar Domestic Hot Water Problem

[Ivan Mezzacapa <ivan_slip@xxxxxxxxxxx>]

Thanks!

could not solve the problem. I do not understand how I schedule it.

In the case of my project, I need to store the water in the tank with 49°. If this starts to cool too much, the gas heating is triggered.

That I am not able to do. 

 Have some data in this example file that could be changed to do this?

I was able to get them to operate independently in the example file

Relevant fields to look into:

in the waterheater:Mixed object,    Deadband Temperature Difference {deltaC}

AvailabilityManager:DifferentialThermostat

but the one that seemed to make the difference was using a 

PlantEquipmentOperation:ComponentSetpoint

instead of the existing plant operation scheme.

I have the same issue as Ivan and it is not clear what I really must do the run a solar collector circuit.

At the WaterHeater:Mixed object, two objects are used in the particular E+ example. The first is the Instantaneous water (which is the electrical or gas heater) and the other is the storage tank connected to the solar collector. What are the exact parameters that must change so the water heater will work only when the water provided by the solar collector does not meet the water set point.

Thank you in advance
