High Discharge Temperature Warning Offset
This parameter is used to set an offset subtracted from the High Discharge Temperature Shutdown parame-
ter. If the discharge temperature exceeds this calculated value, a High Discharge Temperature Warning will
be annunciated. The warning will only be issued if the compressor is running. The value is measured in the
panel temperature units as selected on the Panel Settings screen.
