Hello!
I am wondering if there is a way to assign “Ambient Temperature Thermal Zone Name” for the IB Water Heater Mixed object. This input parameter is available in OpenStudio as per shown below. Many of the input parameters are available but this one is missing in IB. Without the ambient temperature thermal zone assigned, HB Run OSM component gives off the 1. ** Severe ** WaterHeater:Mixed = SHWSYS1 WATER HEATER: Ambient Temperature Zone not found = " error
