MultiSensor
Mymesh Building Light Control
The Mymesh MultiSensor is part of the Mymesh Building Light Control product suite for wire-
less lighting control. The MultiSensor is a motion and light sensor with a lifetime battery for
exible wall mounting. The MutliSensor oers the possibility for daylight harvesting and
automatic light control based on presence and light level.
Application
- Refer to the MultiSensor product sheet (see chess-wise.eu/downloads) for the product
specications and the environmental conditions.
Installation
- Attach the mounting plate with at least 2 screws or double-sided adhesive tape to a wall or
ceiling. Avoid positions vulnerable for mechanical impact (e.g. by transport carts).
- Use the optional 45° mounting bracket to place the sensor under an angle.
- Insert the MultiSensor at one side in the mounting plate and push the switch until it locks.

Installation instruction

Placement
When you mount a MultiSensor on a wall or ceiling, please mind the following:
- Aim the MultiSensor at the desired detectionzone. Refer to the MultiSensor product sheet
(see chess-wise.eu/downloads) for the detection specications.
- Place the MultiSensor on a location without direct or (in-)direct sunlight. Ie; reection of
water or parked cars outside the space.
- Make sure that the MultiSensor is not inuenced by light from another lighting group in your
building.
Examples of placement
Conguration
Use the iPad Mymesh commission app for the conguration of the MultiSensor. First enable
commissioning mode by pressing the hidden button (an arrow is placed on the backside).
When the commissioning mode is activated, the PIR will blink red 3 times. When in
commissioning mode, the motion detector is active. (Red LED = motion detected). After
pressing the button or waiting 60 seconds, the MultiSensor switches back to normal mode.
Possible congurations of the MultiSensor:
- Motion detection (one or multiple sensors)
- Automatic daylight harvesting (with one sensor)
- Motion detection (with one or multiple sensors) and automatic daylight harvesting (with
one sensor).
- Standard conguration for the MultiSensor is motion detection.

Calibration
A MultiSensor with automatic daylight harvesting will calibrate itself during the night, within
24 hours after installation. Part of this calibration is that the connected lights will be briey
switched on. The MultiSensor needs to be re-calibrated when it is moved from its original
position. This can be done via the Mymesh Commissioning app.
Note: the lights can’t be switched o with a oor of building (master) switch.
The automatic daylight harvesting continuously measures the light levels and will restore
the level that was measured during the calibration. If there is a higher presence of sunlight,
the light levels will dim down and with less sunlight, the lights dim up. The benchmark can
be manually changed in the Mymesh Commissioning app.
Usage
After the commissioning process, the MultiSensor will automatically switch back to normal
mode. It will function autonomously within the Mymesh network.
Compliance
This product complies with the European directives and relevant standards for low voltage,
EMC, RED, REACH and RoHS. The Remote switch three button contains a radio. The
