ACCESSORY INSTALLATION
D.1. RC CALEON & RC CALEON WIFI ROOM UNITS
Description
The Caleon unit is equipped with a colour touch screen that
allows you to easily perform all user settings. It includes
a room temperature sensor that allows for more precise control.
It displays temperature and humidity in the room as well as
the outside temperature (the reading is taken from the outdoor
sensor). The unit is offered in a basic version (code 17150) or
with integrated WiFi module (code 18126), which allows control
via the internet from a mobile phone app.
Intended for variants
All variants
Installation
It shall be installed on a wall in a reference room at a height of 1.2
to 1.6 m above the floor, out of direct sunlight and far enough away
from the windows. It must not be installed near heat sources.
Settings in controller
In parameter 5.1.19.5. select the local RC Caleon unit. If the
Caleon room unit selection is not present, there is probably a
fault in the connection between the room unit and the load unit
controller.
For other settings of the room unit please consult the Manual for
RC Caleon.
Connecting terminals
+ – and CAN
El. wiring
Four-core cable (2 for power supply, 2 for CAN bus).
Up to 3 m a standard cable can be used (typically JYTY 4Dx1),
over 3 m a shielded twisted-pair cable shall be used (typically
J-Y(St)Y 2x2x0.8).
Alternatively, the power supply can be solved by a 24V source
located in the room.
The unit will then be connected with the controller using a two-
core cable.
Up to 3 m a standard cable can be used (typically JYTY 2Dx1),
over 3 m a shielded twisted-pair cable shall be used.
