I am trying to create the necessary plant loops for a DHW system with indirect solar thermal pre-heating with a heat pump water heater. I have been able to create both plant loops, but cannot find how to define availability managers. Is this still something that requires a measure that adds them using AvailabilityManager_DifferentialThermostat as discussed in "Fix 2410 - Implemented AvailabilityManagerAssignmentList and all missing AVMs" (https://github.com/NREL/OpenStudio/pull/2844)? Also, I am using the new Water Heater Heat Pump options in OS and there appears to be a disconnect between the Water Heater Heat Pump and Plant Loop. I have added the Water Heater Heat Pump as zone equipment, but the tank defined by the heat pump does not show up in My Model for me to drag and drop the tank onto the plant loop. I cannot drag and drop the water heater heat pump directly onto the plant loop either. Is there a work around for this issue and will it be addressed in the next release? Thanks.
