Operation

Operation via display

EKC 223/224 controllers come with four push buttons, a big display, easy and intuitive menu structure, and pre-
defined applications ensure ease of use.
The values will be shown with three digits, and with a "r05 Temp. unit" setting you can determine whether the
temperature is to be shown in °C or in °F.
To prevent any walk-up user from making unauthorized changes, the access to the display menu is restricted by
access codes. Besides this, the parameter "P76 Keyboard lock" provides the following options for handling of the
display keyboard:
1. The display keys are always operative.
2. The display keys will be locked automatically when not used for some time and the keyboard must be unlocked
by pressing the arrow-up and arrow-down keys at the same time.

Key operations

The buttons on the front of the display can be operated with short and long (3s) presses.
