To optimize control performance, a number of control parameters can be readjusted on the thermostat via HMI, commissioning tool, or Quick Config. These 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 need careful configuration because they impact the thermostat’s control performance and functionality.
