in Thermostats and Controls
Hi all,

Like the title says, what thermostats if any can also control a dehumidifier?
I see the classic Visionpro 8000 series has a so called "dehumidification" setting but that apparently only runs air conditioning to lower humidity. I need one that will close contacts above a certain set point.

So far, the only thing I could find was the Honeywell Humidipro, but it's a separate unit.

Single pipe quasi-vapor system. Typical operating pressure 0.14 - 0.43 oz. EcoSteam ES-20 Advanced Control for Residential Steam boilers. Rectorseal Steamaster water treatment

    I believe the Honeywell TH8321R1001 has a contact that can be used to run a dehumidification system.

    What's the deal with "IAQ" ?

    Indoor air quality. Your able to run humidifiers, dehumidifier, uv lights and Hrvs form it.
    It also has data logging for supply air, return air, run times per hour, day, weeks and months. It will show you data for indoor and out dor temps and humidity.

    Many will. Most of the Vision Pros, Prestige models, any of the VP and Prestige with the EIM. Ecobee3 WiFi. Might need an isolation relay.

    There's a model of the Carrier Edge Pro with dehum contacts. Curiously, I'm unaware of a Trane stat with dehum, but we aren't in as deep with them as some others.

    I found a NOS VisionPro :)
    Never thought I'd type that....

    Only thing I can't tell is if it'll allow a system to fall back to 1 stage cool after the 2nd stage has been energized. Everything else seems to work nice including the dehumidification function.
