Notes on Disposal
As a component of a large-scale fixed installation, Thermokon products are intended to be used permanently as
part of a building or a structure at a pre-defined and dedicated location, hence the Waste Electrical and Electronic
Act (WEEE) is not applicable. However, most of the products may contain valuable materials that should be
recycled and not disposed of as domestic waste. Please note the relevant regulations for local disposal.

Guidelines for Devices with Solar Energy Storage
Due to the energy-optimized EnOcean radio technology used in ”EasySens“ wireless sensors, the devices can work without
batteries and self-charge themselves using electric energy generated by integrated solar cells. This makes the devices almost
maintenance free and environmentally sound due to not having to replace batteries.
For optimum use, the device should be mounted in a location with sufficient ambient brightness. Minimum illumination of 200 lx
(artificial light or ambient) is required for at least 3 to 4 hours each day. (The health and safety regulations at work require a
minimum illumination of 500 lx for office workplaces).
The solar cell should be mounted facing towards the window direction if possible. If the device has a temperature sensor, then
even periodic direct sun radiation should be avoided due to incorrect false temperature readings.
The mounting position should be selected so that the device will not be obstructed in the future: for example by placement areas,
additional furniture or roll-fronted cupboards.
The sensor is supplied in an operational state. If the sensor has been stored in darkness for longer periods, the internal solar
energy storage will most likely need to be recharged. This would normally happen automatically during commissioning or during
initial start up in ambient light. If the initial charge is not sufficient, the sensor will reach its full operating state up to 3 to 4 days, if
the requirements for minimum illumination per day are met. The sensor will then transmit continuously in darkness as specified f
(2/3 days on factory default telegram timing). Depending on the application it is also possible for the devices to operate in darker
rooms (with brightness <100 lx) by using the battery back-up option. Batteries to be used are listed in accessories.
The operating time when using batteries will depend on the transmission frequency as well as the component aging and the selfdischarge of the battery. Standard operating time will be 5-10 years on factory default telegram timing. Changing of the device
from solar to battery operation is done automatically by simply adding a battery to the device.

Configuration with airConfig
NO airConfig needed if default settings will be used. airConfig and a EnOcean USB transceiver (i.e. USB300) will be mandatory
if the default EEP and other settings shall be changed.
Right-click on the device icon and send configuration to initiate the transfer of the new settings. As the sensor will be sleeping it
will need to be woken up by pressing the LRN button. Once the configuration has been transferred successfully into the device
the sensor will be highlighted in green. Highlighted in Red indicates a problem during the transmission.
Note:
The more frequently a device is programmed to wake up, measure and send data, the more energy is being consumed, which
can lead to insufficient energy charge of the sensor by ambient illumination.
