During this test I had a lot of obstructiv apnoes with pressure below 11 and above that it changed more and more to centrals.
The total numbers of apnoes stayed nearly unchanged.
A few suggestions/guesses for you to consider.
Not sure what your Min PS setting is, but you could try increasing it to see if that might help avoid the sweating.
Conceptually, if obstructive apneas are occurring below 11 when in standard CPAP therapy mode, I would think EPAP should be 11 or higher when in ASV (non-Auto) therapy mode, and should be allowed to raise itself to at least 11 when in ASVAuto therapy mode.
Might be interesting to gradually increase Min PS near to your median PS, and then try gradually increasing the Min EPAP and Max EPAP.
But, on the other hand, after gradually raising the Min PS at least to 2, perhaps it would be best to leave EPAP alone and, instead, make sure you will not roll onto your back while asleep.
Obstructive Sleep Apnea is usually strongly positional, and sleeping flat on our back "supine" usually requires higher pressures to treat, which can aggravate complex/central sleep apnea.
If we take measures to prevent the possibility of rolling onto our back while asleep, this will usually lower our pressure needs, which often lowers the number of CA events we get, too.
Some 'PAP users have found marvelous improvement by making sure we won't roll onto our back while asleep. Some sleep wearing a light knapsack on our back with something light but bulky in it. Others sew a sock or pockets onto a teeshirt with a couple tennis balls inside, between the shoulder blades along the spine. Others use long body pillows under the sheet to help remain on their side. Others sleep in comfortable recliner chair so the head and neck are elevated but stay aligned. Whatever it takes.
