Surface mounting
If recessed mounting is not possible,
use the extension frame (E 85 816 69)
for surface mounting. This is not includ-
ed and must be ordered separately
Attach the extension frame to the wall
with screws. Then mount the thermostat
as indicated in the normal instructions.
Fitting with back plate
If the existing frame will not cover the
hole, use an Back Plate. This is not in-
cluded and must be ordered separately
