Installation

Wireless components cannot be installed at
absolutely any location; you must take into
account the effects of structural and other
ambient conditions.
Because attenuation caused by building mate-
rial or other objects in the room is difficult to
calculate, we recommend temporarily fixing
the components and testing them before you
finally install them.
The green LED on the receiver board at the
boiler provides information on the wireless
connection, see section 6.1 on setting up the
box.
