oil pressure should be between .8 and 1bar ish @1k rpm idle, i would set the warning at 0.5bar, oil pressure should be between 3 and 4 bar @3k rpm
the oil temp warning should come in around 115 degrees centigrade, most oils lose viscosity and sludge up @ 120 degrees centigrade, generally hot oil temps should be between 90 and 110 degrees.
