3. Installation of the sensor
Place the thermostat’s floor sensor lead in a
conduit pipe. It is advised to use a conduit pipe
to enable easy replacement in the unlikely case
of malfunction. The thermostat’s floor sensor and
conduit pipe shall be led to the wall module box
of the thermostat. The conduit pipe shall be partly
encased in the floor.
i Important information
Make sure to place the floor sensor of the thermostat between two heating cables, in equal distance.
Secure the conduit pipe as well to avoid floating.
4. Preparation of the subfloor
Clean or vacuum the subfloor removing all kinds of contamination which may damage the cable. The
pre-installation manual presents the method of preparation in detail.
Check the flatness of the floor. Fill in any gaps or uneven parts to prevent cable damage. Install XPS step-
proof insulation board with minimum thickness of 6mm on the whole surface and fix them together with
tape.
5. Read system resistance (1
st
time)
By using an electric measuring device, carry out a resistance reading (between the blue and brown
terminals) and compare the data with the values shown in the table (Section 3.2). Record the date on
the Warranty card. Recorded resistance values may be required during later eventual warranty issues.
Then, read the resistance between the blue, brown and the grounding, which should show an open circuit
reading. For more information on resistance reading see Chapter 5.
6. Placement of the heating mat
I
NEVER CUT OR SHORTEN THE HEATING MAT!
Begin the placement in a way that the connection
cable and the sensor are put on its places when
starting the placement. Lead the connection cable
and sensor cable to the thermostat’s connection
point.
Install the heating mat evenly on the previously
marked places. When reaching the wall, cut the
foil, and turn the heating mat in the needed
direction. Cross-connect the cutted parts of the
heating elements with alu tape pieces provided
to ensure proper grounding. Connect he heating
element parts with the fiberglass aluminium tape
lengthwise.
Make sure that BVF L-PRO is directly fixed to the
floor on the entire surface. Avoid stepping on the
placed heating mat. If it is inevitable, use smooth
bottom shoes.
Remember that cutting the cable is prohibited!
