III.11 Installation of HF temperature sensor
The HF temperature sensor should be installed in a place which is free from electrical
interference and as high as possible. In no case must the HF temperature sensor be
attached directly against a metal wall or reinforced concrete.
Positions near computers or fluorescent tubes should
preferably be avoided.
The temperature measurement must be made in a well-
ventilated place away from direct sunlight. The range of
the signal is approximately 150 metres (in a free field). The
sensor must be slightly out of the box (see photograph
opposite).
It is recommended to test the HF link before attaching the temperature sensor.
Position the plug and the stud before engaging it in the casing. The sensor
must imperatively be pointing downwards for
obvious waterproofing reasons.
By default, the HMT LED clock and the
transmitting sensor are configured on
channel 1. If necessary change channels by
adjusting the position of the DIP switches on
the sensor, in accordance with the channel
selected on the clock, complying with the
following table:
The channel of the receiver clock is configured
in the TECH menu (see page 32).
1. Insert the 3 batteries (type LR6), making sure they
are the right way round, or for the mains version plug
the jack plug in under the central battery.
Caution: do not use the mains version of the HF temperature
sensor outdoors.
2. Check that the LED inside the HF sensor flashes on
each transmission, on average every 15 seconds.
If the receiver is correctly configured, the temperature should
be displayed.
