Rated 1 out of 5 by 1reviewer.
Rated 1 out of 5 Completely unreliable humidity measurement I bought this humidistat to control an exhaust fan for my indoor hot tub. I was attracted to this particular model because of the LCD readout that indicates the current humidity. Most other humidistats just have a knob and don't tell you what the humidity level is.I have now installed a total of 3 1UHE2 humidistats from Grainger, thinking the first two were defective and that I'd get lucky with the 3rd but that was not the case. Here's the behavior I've observed:Humidistat set to De-Humidistat mode, 60% with short delay jumper setting. Turn on the hot tub jets, room starts filling with steam, windows fog up, there's obvious steam in the air that you can see floating around. Humidistat reads 52%. Wait 5 minutes, room is REALLY steamy. Humidistat reads 55%. Water starts condensing on the windows, air is thick with steam and you can tell in every part of the room that the humidity is really high. Eventually I lose patience and turn the knob down to 55% and the fan kicks on. Then it fails to shut off for a LONG time which wastes a lot of heat.I've used my Davis Vantage Pro 2 weather station's indoor module to read the humidity and have observed the 2 devices being up to 26% apart on their humidity reading. The Davis' reading is relatively steady and seems to match what I'd expect the humidity to be (e.g. when it's all steamy in the room, it shows around 75%+, when it feels relatively dry, around 49-55%). The specs say the Dayton device is accurate to +/- 1%, the Davis is rated at +/- 4%. I highly doubt the Dayton lives up to that claim and will be returning the 3rd device for a refund. :-( April 28, 2012
