Got the I-Cabi HD-20 Dry Cabinet from the IT Show and am setting it up. However, dont seem to find any knob to settle for any fine-tuning. Only see a L, M, H switch to toggle the RH setting. Cant seem to find the user manual either. Might have misplaced it or dumped it together with the box.
Is there really a hidden knob for this unit? Or am I stuck with only this switch to toggle the RH levels?
Looks like the L settles around 20-25%, the M settles around 55-60% etc. H probably results in 'ponding'.
Thanks in advance!
