The Winland HAIII+ is a sensor used for monitoring remote locations for rising or falling rates of humidity. A sensing element electronically detects the ambient room humidity to help maintain climate control, even when you aren't in the room.

The HAIII+ is designed and approved to be used with the EnviroAlert® family of monitoring devices including the EA200-12 & EA400-12. The HAIII+ may also be used with Winland legacy monitoring devices including the TA-2HLD, TA-3HLD, UTA-1, DTA-4 & DPM-4.

Important Note: HA-III+ must not be used with monitoring devices that are powered with 24V AC/DC. When used with Winland legacy monitoring devices such as UTA-1, TA-2HLD, TA-3HLD, DTA-4 or DPM-4, the monitoring devices must be set to read Fahrenheit.
