Hi Glenn, is it possible that the "MAX TEMP" setting on the VT unit
itself is set to a value lower than 85C - we have a model L900
temperature controller in our Inova console and use the keypad in the
rear to set the "MAX TEMP" at 50C so users can't damage our triple
resonance probe. Take care, Sean
