General recommendations
Before switching on the unit, read following recommendations:
1 When the complete installation and all necessary settings have
been carried out, close all front panels of the unit.
2 The service panels of the switch boxes may only be opened by a
licensed electrician for maintenance purposes.
3 To prevent the evaporator from freezing and to avoid damage to
the LCD displays of the digital controller, never switch off the
power supply during winter.
OPERATION
The EWAP units are equipped with a digital controller offering a user-
friendly way to set up, use and maintain the unit.
This part of the manual has a task-oriented, modular structure. Apart
from the first section, which gives a brief description of the controller
itself, each section or subsection deals with a specific task you can
perform with the unit.
Digital controller
User interface
The digital controller consists of an alphanumeric display, labelled
keys which you can press and a number of LEDs.

How to enter a menu
■ Digital built-in controller
Scroll through the main menu using the g and h keys to move
the
mark in front of the menu of your choice. Push the q key
to enter the selected menu.
■ Digital remote controller
Press the corresponding menu key indicated in "User interface",
paragraph "Digital remote controller" on page 6
Connection of a remote digital controller to the unit
For a remote digital controller a cable length of up to 600 metres
between the remote digital controller and the unit is allowed. This
gives the opportunity to control the unit from a considerable distance.
Refer to "Cable for remote digital controller" in the installation manual
for cable specifications.
For units in a DICN configuration, the remote digital controllers of the
units can be installed at a distance of up to 50 metres by using a
6-ray telephone cable with a maximum cable resistance of 0.1 Ω/m.
Working with the unit
This chapter deals with the everyday usage of the unit. Here, you will
find how to perform routine tasks, such as:
■ "Setting the language" on page 7
■ "Switching the unit on" on page 7
■ "Consulting actual operational information" on page 7
■ "Adjusting the temperature setpoint" on page 8
■ "Resetting the unit" on page 8

NOTE
Temperature readout tolerance: ±1°C.
Legibility of the alphanumeric display may decrease in
direct sunlight.
NOTE
When a remote digital controller is connected to a
stand-alone unit, the adress of the remote digital
controller has to be set to 2 by means of the DIP-
switches on the back of the remote digital controller.
Refer to the installation manual "Setting the adresses
on the remote digital controller" for setting the adress.
When a remote digital controller is connected to a unit
that is part of a DICN network, the addresses have to
be set according to the instructions in the installation
manual.
