Honeywell Thermostat: TH8320R & TH8321R VisionPro
Re: CONTROL A HUMIDIFIER
Both the TH8320R and TH8321R thermostat can be configured for direct-control of a Humidifier.
► The TH8320R does not have an internal humidity sensor or humidifier outputs so you will be required to add additional REDLink accessories.
