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.
