Hello All, Does anyone know how to calibrate the 'humidity range' on a RCOM-20 (2008 model)? I know how to calibrate it to my hydrometer but I mean actually change the range the machine is set too? I have already tried a master reset but that has not helped.
I have checked my hydrometer is correct so I am confident the inci needs adjusting. Only problem is the machine will not calibrate to the range the hydrometer is in. Hydrometer displaying 50% with inci running at correct temp with water filled, inci displaying 39%. Inci will only calibrate upto to 43% so the humidity range must be out. Despite reading older posts I can not find instructions on how to recalibrate the range. Or should I just run the machine dry and calibrate at a lower humidity level?
Thank you in advance :)
