Recently bought a new dry cabinet but with no manual inside.
Basically is just a knob that either turn towards the blue or red position.
I presume is cold and hot?
I tried the extreme red and extreme blue, the temp remains constant at 28 degree that means my guess is wrong? Then what's the knob for?
I read and seems like I need trials and errors to get in between 55% - 65% RH but today is the 4th day still can't get it right. As in it falls in between but is fluctuating in between and worst is either 65-67 or 52-55.
Not sure if this is ok?
Any idea what's the knob for and hot to get it correct?
Is the extreme 55 and 65 +/- 2% acceptable?
