ACTIVATING AND DEACTIVATING OPTIONAL RH RF SWITCH:
Activation:
Take the ventilation unit plug out of the socket and put it back in again. The
ventilation unit will now search for new switches for 10 minutes. Then take
out the batteries from the sensor and put them back in (see replacement of
batteries of RH RF switch).
Touch the control zone at the bottom right for at least 3 seconds. When all
of the LEDs are flickering you must release the control zone. If the linking
action is successful the LED in the upper left corner lights up green twice,
and on the right a LED lights up that indicates in which relevant position the
RH RF switch finds itself.
Tip: You can link a single switch to a maximum of 3 ventilation units.
Deactivation:
Kill the switch briefly by taking the batteries out of the sensor and putting
them back in (see replacement of batteries of RH RF switch). The switch
can unlink ventilation units for 10 minutes. Touch the control zone at the
bottom right for at least 10 seconds.
When all of the LEDs are flickering for the 2nd time you must release the
control zone. In the event of several activated ventilation units, all activated
units are deactivated as a result. The LED of the switch lights up red four
times in order to indicate that the units are unlinked.
