Air King DH55 Reviews

Rated 4 out of 5 by from Fast response I am impressed with the fast response, I'm using it to dehumidify a bathroom and it ticks on not far into a shower. While rated for 120VAC, the switch is a type that works fine on low voltage systems such as our heat recovery ventilator (HRV). The quality of the construction seems good and I don't expect any problems with this in the future, set it and forget it. While this isn't the best looking product, it should be fine in most applications. With any thermostat or humidistat, you should seal the opening in the wall so the air in the wall doesn't change the setting. "Duct Seal" putty from the electrical department of a hardware store works well.
