Any experience with a Villiger humidor?

Hi all,

A first time humidor user.. I picked up a used large humidor from a tabacco company called villiger.

I'm led to believe that a company called 5th avenue was the original manufacturer.

The hydration pack is just a simple well with a sponge.

As the unit is varnished it's not easy to "season" but after a few days of wet wiping it's settled down.

The mechanical hygrometer is not really accurate. I have a lab calibrated digital unit for comparison.

As I can not set anything to control the rh how do I do that??

Thanks in advance.

Oh..... my house is very warm with a minimum temperature of 25celcius or 77f for our american members, if that makes any difference.
