Product Description
The Q.RCU-D-xx series are versatile communicating sensors which
provideauser-friendlyinterfaceaswellasprecisetemperaturesensing.
Tailored for occupants, the Q.RCU-D-xx intuitive design features
coloured LED indicators to provide user feedback, rotary knobs to
adjust the setpoint oset and fan speed, and a push-button to apply
occupancy override.
As a multi-function room device, the sensor can be expanded with
a combination of up to 4 Q.RCU-D-L Light or Q.RCU-D-B Blind add-
on push-button modules, for lighting and shade/sunblind control,
making it an ideal all-in-one addition to the Room Control solution.
This document describes the hardware installation procedures for the
Q.RCU-D-xx sensors. This line of communicating sensors consists of
the following models:
- Q.RCU-D-TS
- Q.RCU-D-TSO
- Q.RCU-D-TSOF
This document also covers the installation of Q.RCU-D-L Light and
Q.RCU-D-B Blind add-on modules.
General Installation Requirements
For proper installation and subsequent operation of the device, pay
special attention to the following recommendations:
- It is recommended that the device(s) be kept at room temperature
for at least 24 hours before installation to allow any condensation
that may have accumulated due to low temperature during
shipping/storage, to evaporate.
- Upon unpacking the product, inspect the contents of the carton
for shipping damages. Do not install damaged devices.
- The device is designed to operate under environmental
conditions that are specied in its datasheet.
- Ensure proper ventilation of device and avoid areas where
corroding, deteriorating or explosive vapors, fumes or gases may
be present..
- Do not drop the device or subject it to physical shock.
- If the device is used and/or installed in a manner not specied by
SBC, the functionality and the protection provided by the device
may be impaired.
- To ensure reading accuracy, handle sensor with care and avoid
installing on a vibrating surface.
Make connections to the sensor last. Yanking the cable
while it is attached to the sensor can damage the con-
nector.
Any type of modication to any SBC product will void the
product’s warranty.
Take reasonable precautions to prevent electrostatic
discharges to the device when installing, servicing or
operating it. Discharge accumulated static electricity by
touching one’s hand to a securely grounded object be-
fore working with the device.

Q.RCU-D-xx Series

Supported Quantity
The Q.RCU-D-xx sensor connects to the controller’s Subnet Port.
Other devices may also be connected to this port in a daisy-chained
fashion (see the controller’s datasheet for compatibility information
and supported quantities).
Each controller supports a maximum number of Q.RCU-D-xx sensors.
The Subnet ID of all Q.RCU-D-xx sensors must be set to be within the
shown addressing range.
Q.RCU-D-xx Serie sensors and Q.RCU-DC-xx Series sen-
sors share the same Subnet ID range: the same adress
CANNOT be assigned concurrrently to an Q.RCU-D-xx
Series sensor AND to a Q.RCU-DC-xx sensor

1. Adding devices to the subnetwork decreases the system
responsiveness. This may be the origin of a certain delay, which
could be an issue for commands needing a fast response such as
lighting and shades/sunblind commands.
2. The indicated adressing ranges are specic for each group
of device.
4 dierent Subnet ID codications are used on the Q.RC
Subnetwork :
- 1 for Q.RCU-LCD sensors
- 1 for Q.RCU-D-xx and Q.RCU-DC-xx sensors
- 1 for Q.RCS-MS-PL multi-sensors
- 1 for Q.RCE-xx Light/Blind expansion modules
Consequently, a Q.RCU-LCD-x sensor and a Q.RCU-DC-xx
sensor can have the same Subnet ID, but an Q.RCU-D
sensor and a Q.RCU-D-xx sensor must have a dierent
Subnet ID
3. A controller can support a maximum of two (2) Q.RCU-x models
equipped with a CO2sensor. Any remaining connected Q.RCU-X
Sensor models must be without a CO2sensor.
Dipswitch Location and Identication
Q.RCU-D-xx sensors have the following onsite congurable dipswitch.

About the Subnetwork Bus
Controllers use the subnetwork bus to communicate with room
devices (see the controller’s datasheet for compatibility), including
Q.RCU-D-xx sensors, using standard structural (Cat 5e) cabling
by connecting them in a daisy-chained fashion to the controller’s
Subnet Port. See Table 2 : Number of room devices supported by
controller model, and allowed adressing range.
The maximum length of the room device subnetwork bus is 120 m.

Figure 7: Subnetwork Bus Overview
For Q.RC-D1xxx Series controllers, the maximum length
between two consecutive devices on the sub-network
bus is 30 m.
Connection Cable
Connect SBC communicating sensors to the controller’s Subnet
Port with a standard Cat 5e Ethernet patch cable tted with
RJ-45 connectors.
If you make your own patch cable, use Cat 5e cable and
crimp the RJ-45 connectors at both ends of the cable
either as T568A or T568B.
