Connect
Mounting the Control Unit
Mount the Central Control Unit (IV) and if required the Extension Unit(s) (V, VI) on the wall with the screws provided. If you want
to mount them side by side, they can be connected by the provided connection element.
Electrical connection for Control Unit (CCU) and extension Unit(s) (EU)
If the CCU and the EU are mounted side by side, the two units are electrically connected using the supplied cable and connect
it to port no. 20. If the CCU / EU are located further away from each other, they are electrically connected via the ROXi bus
(port 10).

CC – 01
Copper Cable
Connecting the actuators
Max. 16 actuators (XII) can be added to a Sentio system, in
doing so max. two actuators can be connected to each port
at the CCU and one per output on the EU.
Mount the actuators (XII) on the manifold.
1. Screw the grey valve adapter in the manifold by hand
2. P ress the actuator with you hand until you hear a "click"
The actuators are connected with the ports 19 (CCU) or 21
(EU), see page B.
Mounting the room thermostats/sensors
Mount the Thermostat (I)/Sensors (II) on a dry place in the
particular dry, indoor room. It is recommended to choose a
place approx. 1,5m above the floor without draught, stag-
nant air and radiant heat (from sun or electrical devices),
not on an exterior wall or near windows. Do not install them
closed to metal parts or other objects that may interfere with
the radio signals.

If wired room thermostats/sensors are used, connect the
Bus-cable at the terminals "U+, A, B and GND" (port 10).
The room thermostats/sensors are connected to the CCU
by a 2x2 wired, unshielded, twisted pair cable (2x2x24
AWG).
Closing the CCU and EUs
Before closing the CCU/EU ensure that all wires have been
routed through the wiring channels at the bottom of the
units. If the CCU and EU are connected, a part on the front
of the CCU and EU must be removed, leaving space for the
cable between the two units. The front of the CCU/EU is
pressed into place on the base plate and the locking pin (N)
is pushed upwards till you hear a "click".
