Comments about Fantech FH 20 Dehumidistat:

I purchased this to replace a humidistat in a 15yr old Fridgidaire dehumidifier. It turns out to be the exact replacement part. Easy to install and much more accurate than the old one that it replaced. I am thinking of buying an additional one for a bathroom exhaust fan.

I did have to adjust it slightly but, after that it works great and is quite accurate.

Comments about Fantech FH 20 Dehumidistat:

Automatically runs the bathroom exhaust fan when taking a shower (or bath). Using two switches I have manual or automatic function without touching the dehumidistat dial. It may need a few adjustments at first to avoid false starts and possibly seasonally, but so far (one month) it works reliably.

This dehumidistat cost me[$], which was a lot less than a new dehumidifier. It was a simple install; I basically cut a heavy-duty extension cord and installed the unit in a plastic outlet box, which I mounted on the surface of the wall behind the dehumidifier.The FH20 works fine, but at first I found the humidifier to be running too much, so I checked the humidity in the room (with an accurate hygrometer) and found that the room was at 32%, the FH20 was set to 50%, and the dehumidifier was still running.Pulling the cover off of the FH20, I found the usual calibration screw, so I tweaked it until the dehumidifier would shut off close to the actual humidity reading.Since that adjustment, the FH20 has been very accurate.I would recommend the FH20, but advise the installer that he/she might have to tweak the calibration screw. You should check it with an accurate hygrometer during installation.

This dehumidistat works great. I did not mount it on the wall, however. In order for the fan to turn immediately without waiting for the humidity to come down to the level where the dehumistat switch would be mounted on the wall, I took the switch out from the enclosure and mounted it inside our bathroom ceiling fan.

My dehumidifier humidistat went out and I was going to rig this unit up with a recepticle so that I could make my dehumidifier cycle as needed. It turned out that the components of this wall mount unit were the same as the dehumidistat in my dehumidifier. I swapped them and it worked great.
