Overview

Automatic Humidifier Control. This is a 24-volt duct-mounted humidistat. It is capable of operating in automatic or manual mode. In automatic mode, it uses the included outdoor air temperature sensor to compare the outdoor air temperature to an internal program and automatically raises and lowers the humidity setting of your home based on how cold it is outside. The purpose of this feature is to reduce or eliminate fogging of your windows. It can not be wall-mounted. When installed in manual mode it operates without the use of an outdoor air temperature sensor and keeps the humidity setting to whatever level you set it to. We recommend installing it in the automatic mode since this requires less adjustment all winter long.

Older versions of this humidistat included I+ and I- data connections on the terminal block. These are no longer included with this item and you will need to upgrade to the automatic digital humidistat, see related products, for this feature. Most installations did not use these terminals and you should remove the cover of your existing to verify if any wires are connected to I+/I-.
