ush-mountedbox.
5.2.1 Adhesive strip mounting
To mount the DHC Room Thermostat using the adhesive
strips, proceed as follows:
1. Choose a site for installation.
Make sure that the mounting surface is smooth,
solid, non-disturbed, free of dust, grease and sol-
vents and not too cold to ensure long-time adher-
ence.
2. Insert the electronic unit (A) into the wall mounting
plate (see gure 5). Make sure that the electronic
unit properly engages into the wall mounting plate.
3. Fix the adhesive strips on the back side of the wall
mounting plate in the provided area. You should be
able to read the letters (“TOP”) on the back side
(see gure 6).
4. Removetheprotectivelmfromtheadhesivestrips
(see gure 7).
5. Press the assembled DHC Room Thermostat with
the back side to the wall (see gure 7).
5.2.2 Screw mounting
To mount the DHC Room Thermostat with screws, proceed
as follows:
1. Choose a site for installation.
Make sure that no electricity or similar lines run in
the wall at this location!
2. Position the wall mounting plate on the desired site
on the wall. Make sure that the arrows on the back
side of the wall mounting plate point upwards (see
gure 8).
3. Use a pen to mark the positions of the two screw
holes according to the wall mounting plate, with a
distance of 60 mm, on the wall (see gure 8).
4. Drill the marked holes (see gure 9).
If you are working with a stone wall, drill the marked
5 mm holes and insert the plugs supplied. If you are
working with a wooden wall, you can pre-drill
1.5 mm holes to easier insert the screws.
5. Usethe suppliedscrewsand plugstox thewall
