The brightness value set by using buttons is not saved to the non-volatile memory of the
module.
Starting detection of the connected load by using the buttons is only possible when the
automatic mode of load detection is selected for the channel in the ETS program (see full
module manual).
You can also use the buttons to restore factory settings of the module (see “Restoring the
module factory settings
”).

1.1 Load types
The module is designed for use with the following load types:
– resistive (R),
– inductive (L),
– capacitive (C).
After connecting the mains voltage, the module can automatically recognize the type of connected
load. How the connected load will be detected is defined separately for each channel in the ETS
program (see the full manual to the module).
It is recommended that automatic detection of the connected load be performed.
Selecting an incorrect type of load for the channel may damage the module and the
connected load.
You can combine different types of loads within the lighting groups connected to one channel.
Resistive (R) and inductive (L) loads, as well as resistive (R) and capacitive (C) loads can be
combined into groups. For detailed information, see the full manual.
You must not combine inductive loads with capacitive ones. Connecting the loads of
this type to one channel will damage the module.
