I wonder what he keeps in there that requires that kind of treatment.
His prized ISOM's of course
The liquid is 50/50 or distilled?
Distilled water is all thats used!
Are the switches set for a hi/lo RH level, or soecific to timing? If the switches are for timing, how long did it take to figure out you timing to achieve the proper RH? Is that control unit something you designed(I am in electronics)?
There is a sensor that tells the controller the RH & Temp. The sensor is situated inside the humidor in a location out of the flow of any 'fan' forced air. To achieve the EXACT RH
you select a precise 'set point' [within 1/10th % of a degree RH] . When the RH is 'sensed' below the set point, the controller allows current to flow to the Humdifier causing the fans to turn and generate humidity.
You also get to set the control differential [hystersis]. This is the 'sensitity' of the controller. Typically I send out my systems preset to 1/10th %. What this means is: if the set point is 67.5% and the RH is measured at 67.4% or less the humidifier will be activated. When the RH is 67.5 or greater the humidifier is inactive.
The two black knobs are used to regulate the
recirculation fans that run
independently of the RH. Instead they are regulated by an independant timer/relay that cycles indefinately between 'on' and off' . .They 'relay' requires the duration of the 'off cycle' to be set and also the duration of the 'on cycle' . The minimum duration for any cycle ['on' or 'off'] is .25 hours with a maximum duration of 5 hours.
Last question, where did you get the tiny fans? I have been looking for something like that.
Fans came from Mouser or Digikey, I forget which.... ???
