The Wireless test should be performed prior to the wall
installation in order to exclude possible sources of dis-
turbance. Press the SET button of the thermostat in order
to test the assignment of the thermostats or the wireless
transmission. The assigned heating zone will be switched
for 1 minute, independent from the current state of opera-
tion. The channel status changes after each pressing of
the SET button (toggle function). If the Wireless Thermo-
stat cannot be assigned or if the assigned heating zone
cannot be switched during the Wireless test, the reception
conditions for the basis are unfavourable. An external re-
ceiver can be supplied optionally for this case.
This test should only be performed after the Wireless Ba-
sis has performed the first-open function, when the switch
output is not active any more.
