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.

itself, each section or subsection deals with a specific task you can

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"
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.
When a remote digital controller is connected to a
NOTE
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.
