1. Completely loosen the cover screw
2. Carefully remove the terminal box cover from the bottom section. Loosen the two screws in the top
section and remove the top section from the base.
3. Mark the three fixing holes (see ”C.1.1 Housing base”). Make sure that the wall surface is as flat as
possible to prevent the housing distorting when the screws are tightened.
4. Using a drill and a size 6 mm bit, drill three holes in the wall at the points marked and insert the plugs.
5. Mount the controller from the top screw.
6. Insert the two bottom screws and tighten them.
Install the controller only in rooms that are dry and meet the environmental requirements set
out in “B.1 Technical data”.
The controller must not be accessible from behind.
