To optimize control performance, a number of control parameters can be readjusted on the thermostat via HMI, commissioning tool, or the Quick Config app. The parameters can also be set during operation without opening the unit.
Power failure
In the event of a power failure, all settings for control parameter, setpoint, operating mode and changeover value are retained.
The control parameters are assigned to 2 levels:
- Service level, and
- Expert level, including communications, diagnostics and test
The Service level contains a small set of parameters to set up the thermostat for the HVAC system and to adjust the user interface. These parameters can be adjusted any time.
The parameters at the Expert level require careful configuration since they impact the thermostat’s control performance and functionality.
