1. Product Description 2. General Installation Requirements

For proper installation and subsequent operation of the sensor, pay

special attention to the following recommendations:

■It is recommended that the sensor 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 sensors.

■Avoid areas where corroding, deteriorating or explosive vapors,

fumes or gases may be present.

■Do not install onto a direct sunlight source.

■Do not install close to airow (fan coil unit, ceiling air diffuser, etc.).

■The sensor’s datasheet species the power consumption, the

operating temperature range, and other environmental conditions

the sensor is designed to operate under.

■Do not drop the sensor or subject it to physical shock.

■If the sensor is used and/or installed in a manner not specied by

Distech Controls, the functionality and the protection provided by

the sensor may be impaired..

Take reasonable precautions to prevent electrostatic

discharges to the sensor when installing, servicing or

operating the sensor. Discharge accumulated static

electricity by touching one’s hand to a securely grounded

object before working with the sensor.

Any type of modication to any Distech Controls product

will void the product’s warranty.

Operating handling or servicing this product must be

achieved by a qualied operator. Turn off power before any

kind of servicing.

Certain markings (symbols) can be found on the side of the sensor

and are dened as:

CE marking: conforms with the essential requirements

of the applicable EC directives.

Figure 6-1: ECx Subnetwork

EC-Multi-Sensors operate off of a separate sub-bus linked to the

RJ-45 Subnet connector of the compatible ECx Subnetwork device

with an RJ45-RJ45 link. The Network Guide provides extensive

informationandrequirementstoimplement this subnetwork.It contains

information about network length, cable type, addressing, etc. It can be

downloaded from the Distech Controls website.

EC-Multi-Sensor can be freely combined (refer to the master controller’s

datasheet for more specication) in a daisy chain conguration, in

which case an optional ECx Subnet Adapter is required to establish a

pass-through connection.

Cable length between each device of the subnetwork (main HVAC

controller / ECx-Light/Blind expansion modules / RJ-45 Accessories)

should not exceed 30 m (100 ft).

The total maximum length of the Subnetwork bus is 180 m (600 ft).

6. Subnetwork Communications Wiring

The last daisy-chained subnetwork device must have its

EOL resistors enabled / installed. All other devices must

have their EOL resistor disabled.

If the EC-Multi-Sensor is not the last device on the ECx

subnetwork, it must be daisy chained using an ECx

Subnet Adapter. To do so, simply clip the ECx Subnet

Adapter male connector into the EC-Multi-Sensor,

and connect the next and previous devices to the

ECx-Subnet Adapter female connectors, one in each

plug.

7. SubnetworkBusTopologyandEOLTerminations

When ECx subnetwork devices are installed with a PTU Series or VAV

controller, only the last device (expansion module or room device)

EOL termination is set to ON. All other devices must have their EOL

terminations set to OFF.

The EC-Multi-Sensor’s EOL termination is dened by the absence or

the presence of the EOL jumper:

■Absence of EOL jumper: EOL termination OFF

■Presence of EOL jumper: EOL termination ON

Figure 7-1: EOL termination ON

Figure 7-2: EOL termination OFF

8. Device Addressing

Each EC-Multi-Sensor on the ECx Subnetwork must be set to a unique

subnet ID address. The address is set either with the rotary switch

located at the rear of the sensor using a small screwdriver (≤ 2.5 mm -

0.1’’) or with an EC-Remote-I.

■The Subnet ID address must be set before installing

the sensor, as the rotary switch might not be

retrievable once the rear spring installed.

■4 different Subnet ID codications are used on the

ECx Subnetwork :

– 1 for Allure EC-Smart-Vue sensors

– 1 for Allure EC-Smart-Comfort and Allure

EC-Smart-Air sensors

– 1 for EC-Multi-Sensors

– 1 for ECx-Light/Blind expansion modules

Consequently, for example, the same Subnet ID can

be assigned to an ECx-Light/Blind module, to an

EC-Multi-Sensor and to an Allure EC-Smart-Vue sensor

without any adressing issue.

Figure 8-2: Setting the EC-Multi-Sensor Subnet ID Address

Automatic addressing shall only be used if only one

EC-Multi-Sensor is connected to the ECx Subnetwork.

Figure 8-1: EC-Multi-Sensor Rotary switch

Setting the Subnet ID with the rotary switch

Set the desired Subnet ID by pointing the matching number with the

rotary switch arrow

When setting the Subnet ID using the EC-Remote-I, the

rotary switch must be set to 0 (default).

Setting the Subnet ID with the EC-Remote-I

1. Press simultaneously on the remote

control for 3 seconds: the remote control displays MAC for

1 second, followed by the current Subnet ID (default: 1).

2. Set the Subnet ID with and .

3. Press to validate.

If neither nor is pressed for 5 seconds, the

Subnet ID menu is escaped and the Subnet ID is not

modied.

The Subnet IDs that can be allocated to EC-Multi-Sensors are 0

(factory default), 1, 2, 3, and 4. All other adresses are not used.

As the measured temperature is at ceiling height, it must be necessary

to apply an offset to this measure to represent the room temperature

at standard level. Please refer to EC-gfxProgram User Guide for more

information.

Temperature sensing

9. Settings

The Waste Electrical and Electronic Equipment (WEEE) Directive

sets out regulations for the recycling and disposal of products. The

WEEE2002/96/EG Directive applies to standalone products, for

example, products that can function entirely on their own and are not a

part of another system or piece of equipment.

For this reason Distech Controls products are exempt from the WEEE

Directive. Nevertheless, Distech Controls products are marked with

the WEEE symbol , indicating devices are not to be thrown away

in municipal waste.

Products must be disposed of at the end of their useful life according

to local regulations and the WEEE Directive.

10. Disposal

Changes or modications not expressly approved by

Distech Controls could void the user’s authority to operate

the equipment.

This equipment has been tested and found to comply

with the limits for a Class B digital device, pursuant to

Part 15 of the FCC Rules. These limits are designed

to provide reasonable protection against harmful

interference in a residential installation. This equipment

generates, uses and can radiate radio frequency energy

and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio

communications. However, there is no guarantee that

interference will not occur in a particular installation. If

this equipment does cause harmful interference to radio

or television reception, which can be determined by

turning the equipment off and on, the user is encouraged

to try to correct the interference by one or more of the

following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and

receiver.

• Connect the equipment into an outlet on a circuit

different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV

technician for help.

The infrared receiver can be used to associate the EC-Multi-Sensor

to an EC-Remote-I. The matching sight range can be viewed in the

EC-Multi-Sensor datasheet. The default infrared zone number is 0.

This parameter can be modied using EC-gfxProgram. Please refer to

EC-gfxProgram User Guide for more information.

Infrared reception

11. FCC Statement

As the luminosity level in a room is not homogeneous but depends

on the measurement position and on the room layout (colors, desk

position, light sources...), the luminosity level acquired by the

EC-Multi-Sensor might not be the luminosity level at the workplace.

To precisely measure the luminosity level at the desired position, a

calibration must be achieved.

■Please note that the luminosity level calibration must

be achieved at the approximate desired luminosity

level.

1. Position the luxmeter at the exact position the user operates

(typically on a desk).

2. Note the luminosity level value.

3. Luminosity level calibration can then be achieved by entering this

value using the dedicated EC-gfxProgram custom block.

Luminosity level measurement calibration

To achieve luminosity level measurement calibration:

Motion sensitivity can be adjusted in EC-gfxProgram so as to avoid

unwanted interferences while ensuring actual movements remain

detected. Please refer to EC-gfxProgram User Guide for more

information.
