15. Information about radio operation
Transmission of data between heating control and valve op-
erating mechanism is performed wirelessly per radio trans-
mission.
The transmitting power is less than 10mW, i.e. much below
the transmitting power of a mobile phone which may have
a transmitting power that is 200 times as great. Therefore,
negative effects on sensitive people or animals are not to
be expected.
The radio heating thermostat system works in the 868MHz
range which is also used by other radio services. There-
fore restrictions in the operation and the range can occur
through the devices which work on the same or neighbour-
ing frequency.
The range stated of up to 100m is the free-field range, i.e.
the range at sight contact between the transmitter and the
receiver.
