There are a number of issues with your model. First, you have a water heater
connected to a fluid system of type “HotWater.” This should be type =
“ServiceHotWater.” Type = HotWater are used for heating hot water only.
Correcting this corrected the error having to do with the water heater required
inputs.
However, the water heater is specified as type = Storage, but you have storage
capacity of 1 gallon. This is too low for storage water heaters, so I changed
the type to instantaneous. If it is a storage water heater, then the storage
capacity should be significantly higher.
Also, on the project screen under Exceptional Conditions you have the condition
that service water heating is excluded from the building set to yes, while a
service hot water system is defined in the model. I set this condition to
“No.”
For the HVAC system, you have the supply fan and the heating coil on different
supply air segments, these should be on the same air segment. Normally, air
systems will have one supply segment and one return segment. Then all the
terminal units will be connected to the one supply segment. These two air
segments will also be referenced by the outdoor air control object.
I think if you correct these issues, you should get a working simulation. Let
me know if you have additional problems.
Noah, I think we need a checksim that catches water heaters attached to fluid
systems that are not ServiceHotWater.
