INFORMATION
On power up, the default update mode for all holding registers
is LastTouch (0).
6.4.3 Control limiting
The holding registers for control limiting allow adjustments to settings
made by a remote controller or a central controller to be limited to
specified ranges. In case of setpoints, optional limitation of minimum
and maximum values is possible. Fan speed, airflow direction and
mode controls can also be limited to specific settings using an inhibit
value. When the limit value is set to 0, no control limiting is applied.
The inhibit values for fan speed, mode and airflow direction are
calculated by adding together the individual inhibit values for each
setting to be inhibited. Example: You want to limit the possible
operation modes someone can select with the remote controller (or a
central controller) to Heating and Cooling. The inhibit values of the
Auto, Fan and Dry modes are added together: 1 (Auto) + 4 (Fan) + Dry
(16) = 21. In this case, 21 is the correct inhibit value.
