A number of control parameters can be readjusted to optimize control performance. This can be done on the thermostat via HMI or via commissioning / operating tool. These parameters can also be set during operation without opening the unit.
In the event of a power failure, all control parameter settings are retained, see page 53.
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.
Change parameters at the "Expert level" carefully, as they impact the thermostat’s control performance and functionality.
