Re: OPERATING A HUMIDIFIER

Once a VisionPro thermostat has been configured for Humidification, you can control a humidifier directly from the thermostat interface.

To operate a humidifier from a VisionPro thermostat, you must set the Humidification Mode and the Humidity setting.

From the Home Screen press the MENU tab.
Highlight "Humidification" and press Select.
Use the Left and Right arrows to change the mode to either "Off" or "Auto".
- In the "Off" mode, all Humidifier outputs will remain de-energized regardless of the humidity level.
- In the "Auto" mode, the thermostat will energize the humidifier outputs when Heating is "On" and the sensed humidity level is lower than the desired humidity setting.
Use the Up and Down arrows to set the desired humidity level.
- A normal Winter humidity level is typically between 25 to 40%.
Once settings have been made press "Done", and a screen will appear showing that the changes are being saved.
Press the HOME tab to return to the Home Screen.
