Installation and Connection
Control overview
The infra-red remote control variant offers the option of
operating the cassette using an infra-red transmitter
supplied separately. A number of other functions can be used
via inputs and outputs CA/CF and D0 that can be confi gured
using DIP switch D1. In addition, up to 20 units in one group
can be controlled with a remote control.
CA input: On/Off or Heating/Cooling
Input CA can be used to process a centralised signal (e.g. from
a building control system). The cassette reacts according to the
external command depending on the setting on DIP switch 9
(D2/D1).
CF input: External On/Off
Input CF can be used, for example, to integrate a window
contact or presence detector.
Remove jumper MC1 if the contact is used.
Output D0 can be used to pass the current status of the
cassette to an on-site controller. The output indicates whether
the cassette is switched on or off or whether the fl oat switch
signals a condensation fault depending on the confi guration of
DIP switch 8.
