This pre-wired humidistat is an ideal means of control for the HRSM in humidification applications requiring 80% or less relative humidity. For applications above 80% RH you (should not purchase this control) should operate the unit continuously, and throttle the fogging output to the right setting to achieve desired high RH level.

Automatically controls your Aquafog HRSM for most indoor humidification applications. It incorporates a fast-acting man-made sensing element with a large, easy access control dial. Designed to endure high humidity levels up to 80%, this control unit requires no wiring and comes with a Nema 4X watertight junction box containing a motor starter relay and convenient pre-wired electrical cords.
