4.14 Control parameters
A number of control parameters can be readjusted to optimize control performance.
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.
The control parameters are divided in two levels:
· “Service” level, and
· “Expert” level, including Diagnostic and Test
The “Service” level contains a small set of parameters to set up the controller for
the HVAC system and to adjust the user interface. These parameters can usually
be adjusted any time.
Change parameters in the “Expert” level only carefully, as they impact control
performance and functionality of the controller.
Change the parameters as follows:
1. Set the controller to Protection *)
2. Press buttons + and - simultaneously for 4 seconds.
Release and press button + again within 2 seconds until the display shows
“P01”.
Continue at Step 3.
1. Set the controller to Protection *)
2. Press buttons + and – simultaneously for 4 seconds.
Release and press button – again within 2 seconds until the display shows
“P01”.
