(1) If Control Variable is set to Maximum Temperature, the SPM symbol disappears, including the visual handle for deleting the setpoint manager.

(2) When opening an 1.4.0 osm-file with OpenStudio 1.8.0, in the plant loop schematic the symbol for a setpoint manager manager gets lost if Control Variable was set to Maximum Temperature in the 1.4.0 osm-file, lost, although apparently the data associated with the setpoint manager have been read in. in.
