Description

The MFR012 is designed to control therelative air humidity inside of enclosures.When connected to an enclosure heater,(de-humidifier), it will turn the heater on atthe set humidity level in order to raise thedew point. This helps prevent damage andmalfunction of electronic componentscaused by condensation and corrosion. TheMFR012 can also be used to control coolingfans, warning lights or other devices.

Will the MFR0122 work to de-humidify ( turn on a make up air unit ) a wand-wash car wash bay? Do the contacts close on humidity rise? and switch on 24VAC?

Asked by: Humidor
Thank you for your inquiry. This product is designed to be installed in an enclosure to monitor the relative air humidity and control an electric heater to dehumidify the air within enclosure. It cannot be installed outdoors or in a location with direct exposure to water.
