3.14 Control parameters

A number of control parameters can be readjusted to optimize control performance.
This can be done on the thermostat using the HMI, or the 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 section 3.14.
The control parameters are assigned to one of the two levels:
· Service level - 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.
· Expert level including communications, diagnostics and test. - At the Expert
level, you must change the parameters carefully since they impact the
thermostat's control performance and functionality.
