3.4. Installing the window contact
► Connect any sensor with floating contact to the HCW 82
(installation to connection 1 and connection 2, see
Fig. 7(2), Page 9).
► Assign the HCW 82 to the Hometronic Manager
HCM 200D as a sensor (refer to the HCM 200D
instructions "Assigning a room to a sensor").
If several floating contacts are used, these have
to be connected in series.
4. Changing batteries
Change the batteries if the red LED of the room temperature
sensor flashes and the device is not in test mode.
► Remove the housing cover of the HCW 82/HCF 82
(see Fig. 1).
► Remove the batteries.
Dispose of the batteries according to the
local statutory requirements and not with
the used domestic refuse.
Always replace both batteries together.
Only use 1.5 V batteries of the type LR06, AA.
► Insert the batteries with the right polarity into the batteriy
compartment (see Fig. 2).
► Place the housing cover on at the top and latch it in
downwards (see Fig. 4).
5. Checking radio
transmission
The HCW 82/HCF 82 can send a test signal to the allocated
receiver (for example an underfloor heating controller) in
order to test the signal strength.
► Keep the teach-in button pressed for at least 30 s until the
red LED extinguishes.
The device is now in test mode and sends a test signal
every 5 seconds.
The LED flashes briefly at every test signal.
► Check the radio transmission at the receiver. Refer to the
respective instructions for information about receiving and
evaluating the test signals.
The test mode is terminated automatically after
5 minutes. The test mode can also be terminated
by removing the batteries, disconnecting the
power supply or by pressing the teach-in button.
