Function and device overview

The Homematic IP CO2 Sensor reliably and accurately measures the CO2 concentration, temperature and humidity in your smart home. This enables automatic monitoring of the indoor air quality. With the free Homematic IP smartphone app, you can always keep an eye on the measured values.
The device can be easily mounted in a flush-mounted box. In addition to the phase, a neutral conductor is also required for the connection.

An additional relay output enables the device to control a connected consumer, e.g. a lamp. The light can be easily switched via remote controls, wall- mounted push-but-tons, motion detectors or via the Homematic IP app. A flush- mounted box can thus be used simultaneously for the CO2 sensor and for light control.
Thanks to its 55 mm design, the sensor can be easily integrated into existing frames of common brand man-ufacturers. The design, colours and surfaces of switches already installed remain unchanged.

Installation

To install the device in a flush-mounted box, please proceed as follows:

•  Switch off the circuit breakers of the power circuit (see figure 3).
•  For installation, use an empty flush-mounted box with a neutral conductor in addition to the phase conductor and the connecting cable for the lamp.
• If you do not have an empty flush-mounted box available, you can alternatively replace an al-ready installed switch by the smart solution from Homematic IP.
•  Therefore, pull the rocker off the frame of the in-stalled switch. Then pull the frame off the switch together with the clamping/retaining piece. The clamping/retaining piece can be transparent, grey or black (depending on the manufacturer) and holds the frame onto the switch.

NOTE:

• To make removal easier, a flat, pointed object such as a slotted screwdriver can be used.
•  Loosen the fastening of the existing switch and carefully remove it from the flush-mounted box.
•  Disconnect the existing cabling from the switch.
•  Connect the power supply unit (A) of the CO2 sensor according to figures 4 and 5. Make sure that you can read the text on the front after wiring.
•  Secure the voltage supply unit using the provided screws into the flush-mounted box (see figure 6).
•  Place the clip-on frame (B) on the voltage supply unit (see figure 7). Alternatively, you can continue using your existing (multi-gang) frame with an inner dimension of 55 mm (see figure 9).
•  Place the electronic unit (C) of the CO2 sensor into the clip-on frame so that the contacts of the electronic unit latch into the voltage supply unit (see figure 8 or 9).
•  Switch the fuse of the power circuit on again to activate the teach-in mode of the device (see figure 10) (see “5.1 Installation instructions” on page 40).

Information on CO2 pollution

As CO2 sensors generally tend to deviate further and further from the real measured values over a longer period of time, the sensor installed in this device is equipped with an integrated calibration mechanism. In order to compensate for the CO2 deviations over longer periods of time and to be able to measure precisely even after longer use, the CO2 sensor performs an automatic adjustment in the background.
In order for this mechanism to work, you should venti-late sufficiently at least every 8 days to prevent incorrect measurements.

NOTE:

• The interval at which this calibration takes place is set to every 8 days by default. The function can be individually adjusted or deactivated via the Homematic IP app or the WebUI.
• CO2 pollution can become noticeable already from 1000 ppm through tiredness, lack of con-centration and headaches.

Five illuminated LEDs (D) on the top of the unit indicate the CO2 load in the room:

NOTE:

• ppm = air quality indicator
• The maximum value in indoor areas should not exceed 1500 ppm.
• The CO2 sensor provides a configurable switching threshold. This can be defined individually via the Homematic IP app or via the WebUI, e.g. in order to switch on a light once a certain CO2 lev-el is reached.

Troubleshooting

Command not confirmed

If at least one receiver does not confirm a command, the device LED (E) lights up red at the end of the failed trans-mission process. The failed transmission may be caused by radio interference (see “10 General information about radio operation” on page 52). The failed transmission may also be caused by the following:

•  Receiver cannot be reached.
• Receiver is unable to execute the command (load failure, mechanical blockade, etc.).
•  Receiver is defective.

Duty cycle

The duty cycle is a legally regulated limit of the transmission time of devices in the 868 MHz range. The aim of this regulation is to safeguard the operation of all devices working in the 868 MHz range.
In the 868 MHz frequency range we use, the maximum transmission time of any device is 1% of an hour (i.e. 36 seconds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction comes to an end. Homematic IP devices are designed and produced with 100% conformity to this regulation. During normal operation, the duty cycle is not usually reached. However, repeated and radio-intensive teach-in processes mean that it may be reached in isolated in-stances during start-up or initial installation of a system. If the duty cycle is exceeded, this is indicated by one long red lighting of the device LED (E), and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

Error codes and flashing sequences

Please try again (see sec. “7.1 Command not confirmed” on page 48 or “7.2 Duty cycle”

on page 48).

Short orange flashing (every 10 s)| Teach-in mode active| Enter the last four numbers of the device serial number to confirm (see “5.3 Teaching-in” on page 44).
6x long red flashing| Device defective| Have a look at your app for error message or contact your retailer.
1x orange and 1x green lighting| Test display| Once the test display has stopped, you can continue.

Restore factory settings
The factory settings of the device can be re-stored. If you do this, you will lose all your set-tings.

To restore the factory settings of the device, proceed as follows:

• Press and hold down the system button (E) for 4 seconds until the device LED (E) starts to flash quickly orange (see figure 12).
• Release the system button again.
• Press and hold down the system button again for 4 seconds, until the LED lights up green (see figure 13).
• Release the system button to finish the procedure.

The device will perform a restart. After the restart, you can again integrate your device into your Homematic IP system.

Maintenance and cleaning

WARNING:

The product does not require any maintenance. Enlist the help of an expert to carry out any repairs.
The mains voltage must be disconnected before the device is removed (trip the miniature circuit-breaker). Only qualified electricians (to VDE 0100) are permitted to carry out work on the 230 V mains.

Clean the device using a soft, lint-free cloth that is clean and dry. Do not use any detergents containing solvents, as they could corrode the plastic housing and label.

General information about radio  operation

Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring. Interference can also be caused by switching operations, electrical motors or defective electrical devices.

NOTE:

The range of transmission within buildings can differ greatly from that available in the open air. Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/screening conditions.
