That input field refers to the location within a list of material layers at which a temperature calculation is performed, which can be useful when simulating radiant systems. The input is described in the I/O reference here, and details about how the temperature is calculated within the construction can be found here. The temperature can be output by including the output variable Surface Internal Source Location Temperature.
