You can manage application settings by turning on/off a specific function or change setting values. It is strongly recommended that only installers or experts with detailed know-how about the thermostat modify the application settings.
NOTE:
- Parameter availability depends on your selected application for your thermostat.
- Numbers marked in tables are only for easy readability in this document. They don't represent the parameter numbers in the local hardware unit.

NOTE: Humidification control works with a PID algorithm if the connected humidifier is in "AUTO" mode. The algorithm continuously monitors the difference between the humidity setpoint for humidification and the measured relative air humidity in the room and switches on and off the humidifier to keep room humidity above the setpoint. The humidifier cannot be manually switched on and off in this mode. Changes to the setpoint affect humidification control and verifying functionality.
