Advanced Features Of The Digital Controller - Daikin EWLQ014KBW1N Operation Manual

Advanced features of the digital controller

This chapter gives an overview of the direct parameters and user
parameters provided by the controller. In the following chapter, you
will learn how you can set up and configure the unit using these
parameters.
Overview of the direct and user parameters
The list of direct parameters is accessible by pressing the B key
for approximately 5 seconds. Refer also to "How to consult and
modify the direct parameters" on page 8.
