3 DESIGNING FLOOR HEATING AND CHOOSING THE PRODUCT
3.1 Pre-installation planning
1. Assess the surface to be heated
Define the surface to be heated by leaving out the territory covered with fix furniture (wardrobe) and
obstacles (shafts etc.) Calculate the size of the surface to be heated.
Example: the wardrobe shown on Figure 2 is 8.75 m². When deducting the area covered by the wardrobe
and shafts the remaining area is only 6.45 m². Choose the 6 m²size heating mat with the competent
capacity.
2. Check grid voltage and available capacity
The system operates on 230 V alternate current. Check the available load capacity, and request extension
from the provider if necessary.
3. Design the system
Plan the optimal placement of the heating mat with full coverage. When defining the place of the
thermostat, take note of the 2.5-meter-long connection cable of the heating mat required to reach the
thermostat, as well as of the signal transmitter of the thermostat in the floor to be in adequate distance.
It is advised to lead/install the connection cable of the heating mat from the place of the thermostat. See
Figure 3.
i Important information
To ensure even heat distribution, keep cable distance as set by default during installation.
By increasing cable distance, cooler floor areas may be created.

proof insulation board with minimum thickness of 6mm on the whole surface and fix them together with
tape.
5. Read system resistance (1st 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!

User Manual for
BVF L-PRO
floor heating system
1. Ensure the electric floor heating’s steady heat radiation, avoid placing sizeable objects/
furniture without legs on the floor.
2. Avoid covering the floor with materials having high thermal insulating qualities
(thick rug, mattress, under-bed bin, thermal proof materials, etc.) during operation.
3. Protect floor covering from moisture, long-term wetting.
1. Calibrate the thermostat using a room thermometer, since default settings of any type may
be different than the actual temperature. (For details see the User Manual of the actual
thermostat)
2. In case of individual heating, place the sensor operating mode of the thermostat to double
(floor+room) position, where the thermostat shows the air temperature based on data
provided by the built-in sensor, and the floor sensor sets the limit temperature of the floor
(heat sink) in the value of the set temperature.
3. Set the disable temperature of the floor sensor to 29-31°C. (For details see the User Manual
of the actual thermostat)
4. If the system is equipped with a programmable thermostat, for the most efficient operation
the use of programming functions is advised.
5. BVF L-PRO floor heating system is NOT a heating storage or partly heating storage system,
thus shorter heating-up times shall be taken into consideration when starting and
programming heating cycles. Heating-up, depending on the floor’s original temperature
and thickness (thermal storage capacity/thermal inertia) may take longer time.
6. During the heating season, for the best results, avoid turning off the heating system, when
out of use set air temperature back by 3-4°C the maximum, thus preventing the overcooling
of walls and other devices. In case the heated premises are to be out of use for a longer
period, the use of anti-freeze program option is advised for conservation purposes.
