Daikin EWLQ014KBW1N, Operation Manual

Page: 8 / 174

Keys provided on the controller:
The function carried out when the user presses one or a combination
of these keys depends on the status of the controller and the unit at
that specific moment.
LEDs provided on the controller and remote interface:
Function during main display (not inside menu)
When selecting a parameter group or parameter, different LEDs
related to the parameter group or parameter are displayed.
Example: The LEDs F and G are displayed when accessing a
parameter group or when accessing parameters directly.
Direct and user parameters
The digital controller provides direct and user parameters. The direct
parameters are important for the everyday usage of the unit, e.g. to
adjust the temperature setpoint or to consult actual operational
information. The user parameters on the contrary provide advanced
features such as adjusting time delays.
Each parameter is defined by a code and a value. For example: the
parameter used to select local or remote on/off control has code
h07
and value
1
or
0
.
For an overview of the parameters, refer to "Overview of the direct
and user parameters" on page 10.
