Caution
C.1 Wall installation
Install the controller only in dry areas and under the ambient conditions descri-
bedunderB.1„Specications“.Carryoutthefollowingsteps1-8.
1. Unscrew cover screw completely
2. Carefully pull upper part of housing
from lower part.
3. Set upper part of housing aside, being
sure not to touch the electronics when
doing so.
4. Hold the lower part of the housing up
totheselectedpositionandmarkthe3
mountingholes.Makesurethatthewall
surface is as even as possible so that
the housing does not become distorted
when it is screwed on.
5. Using a drill and size 6 bit, drill 3 holes
atthepointsmarkedonthewalland
push in the plugs.
6. Insert the upper screw and screw it in
slightly.
7. Fit the upper part of the housing and
insert the other two screws.
8. Align the housing and tighten the three
screws.
