INTRODUCTION

The CMa10w/CMa11w is a 1-way wireless M-Bus communicating

temperature and humidity sensor for indoor use.

For a complete description of the product or for information in Swedish,

visit the Elvaco AB website, www.elvaco.com.

OVERVIEW

CMa10w/11w

Indoor wireless M-Bus temperature and humidity sensor

1. Push-button (SW2) (CMa10w)

2. Display (CMa10w)

3. LED 1

4. Push-button (SW1)

5. Serial number (identiﬁcation)

6. Do not use for mounting

MOUNTING

When mounting the CMa10w/CMa11w, avoid rooms with a lot of

supplementary heat, such as kitchens or south facing rooms. Position

the sensor away from direct sunlight. Avoid placing on an external wall

or near an external door. Make sure that the sensor is not positioned

closer than 1 m from the nearest radiator and at least 1.5 m above the

ﬂoor.

The CMa10w/CMa11w can be mounted directly on the wall, or over a

mounting box. If the CMa10w/CMa11w is placed over a conduit pipe,

it is recommended to ﬁll the pipe to prevent air ﬂow which could affect

accuracy of the values.

Remove the rear cover to be able to press the installation button SW1

(4).

IMPORTANT

• Do not use mounting holes (6) as shown in overview.

• Turn the rear cover as shown in the overview.

• Do not mount the product inside a steel cabinet, which will

dramatically lower the possibilities to connect to a master.

• If the product should be demounted from the wall, use a

screwdriver to separate the product from the rear cover. The

screwdriver should be inserted carefully in the upper part of the

holes as shown in the ﬁgure.

WIRELESS M-BUS

The product is delivered with the radio turned off. The radio must be

manually switched on during the installation procedure.

The product will not be activated until the installation procedure is

started.

INSTALLATION

The product can be installed and enabled in two modes. Please advise

your project manager which operation mode is used in your project.

Unencrypted mode: Meter data is sent unencrypted and the encryption

key is not needed to decrypt the data.

1. Press and hold button SW1 (4) for 6 seconds, until LED1 (3)

ﬂashes quickly.

2. Release SW1 (4).

Encrypted mode: Meter data is sent in encrypted mode and the

encryption key is needed to decrypt the data.

1. Press and hold button SW1 (4) for 13 seconds, until LED1 (1)

ﬂashes slowly.

2. Release SW1 (4).

* If the button is released in this mode, the CMa10w/CMa11w will return to

inactive mode. This also applies if the button is pressed down for longer than

25 seconds.

IMPORTANT

Make sure that the product is activated by pressing SW1 in normal

operation. If the product is activated, LED1 will ﬂash shortly.

OPERATION

The product will automatically, after the installation procedure, send

T1 messages every 6th minute containing sensor data, such as

instantaneous temperature and humidity. The product will also send

product status information, containing battery status and other relevant

information.

CONFIGURE USING LCD DISPLAY (CMA10W)

The display shows current sensor information when push button SW2

is used. The display is also used to change and view the CMa10w

conﬁguration. The display is turned off in normal operation mode. End

users only have access to the Standard menu. The Setup menu can only

be entered using the push-button SW1 on the rear of the product.
