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 m² size 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.

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.

• Cable stripping tool
• Measuring tape
• Screwdriver
• Electric measuring device/multimeter

1. Make a drawing of the layout
   Make a drawing or sketch indicating planned layout. Indicate every area covered by fix shafts, obstacles etc.) Calculate the size of the surface to be heated. Write down all the needed size data for the surface to be heated, and define the place of the thermostat and the floor sensor.

2. Copy the drawing onto the floor
   Draw the outlines of the planned system on the floor. Leave out the places of devices to be placed as fix later. Roll out and place the first couple of meters of the heating mat. The starting point of the cable should not be more than 2.5 meters away from the thermostat.
   Important information
   Make sure that the connection point (connection cable – heating cable) of the BVF L-PRO cable is placed in a conduit. Make sure to place the floor sensor of the thermostat exactly in between two heating cables (on heated surface), in a distance at least 65 cm from the wall, in a conduit pipe, to enable replacement if necessary.

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.

Important information
Make sure to place the floor sensor of the thermostat between two heating cables, an 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 a 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

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 cut 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

HEATED FLOOR/COVER

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.

CONTROL

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.
