General information
Intended use
Packaging content
Hydroclima 2 is a 2nd generation two-sensor electronic heat cost allocator. It is used to indirectly measure the
consumption of thermal energy emitted by a radiator.
The allocator calculates dimensionless consumption units according to the radiator temperature and room
temperature. It can also register historical data concerning temperature, heat consumption and other statistics. All
data can be sent via Wireless M-Bus protocol, based on Bmetering software configuration.
The device is designed for the metering of central heating systems with vertical heating medium distribution. The
building’s heating costs are calculated based on the units registered by the allocator.

Installation
General installation rules
1. The allocator is installed on the radiator in two steps. First the aluminium heat sink must be attached to the radiator.
2. The electronic heat cost allocator (heat sink) should be installed at 75% of the radiator’s height, counting from
the bottom. (i.e. at 3/4 of the radiator’s height) and exactly in the middle of its width. Exceptions from this rule are
presented further in this document. The installation error margin is ±1 cm. (See image below)
3. If it is not possible to install the allocator (heat sink) precisely in the middle of the radiator’s width, move it closer to
the side on which the heating medium supply pipe is located. Detailed information regarding this type of situation
can be found in this document.
6. Install the heat sink according to the installation technique (see point 4 – Installation techniques), aligning the
special groove with the previously measured installation point.
4. If the total height of the radiator is less than 470 mm, the allocator (heat sink) should be installed in the middle of
its height.
7. Place the allocator on the heat sink.
8. Close the allocator with a seal at the bottom.
5. The installation height of the heat sink must be measured from the hole in the middle of the heat sink.

Installation on radiator heaters
9. To ensure the heating cost calculation is correct, it is necessary to install all allocators of a given radiators at the
same height.
. In the case of an even number of heating elements the allocator (heat sink) should be installed in the middle of the
width and at 75% of the height measured from the bottom of the radiator:
b. In the case of an even number of heating elements, when the radiator’s mounting pin is located in the middle, the
allocator (heat sink) can be moved one heating element toward the radiator’s supply. The installation height should
remain the same (75%):
10. When performing the installation or stocktaking of allocators, the rooms in which they are located should be
described in clockwise order. (See image below)
The allocator (heat sink) should be installed using a properly selected mounting bracket.
Please consult the following installation cases:

5
HYDROCLIMA 2 - User Manual
c. In the case of an odd number of heating elements and when it is not possible to install the allocator in the middle
of the radiator’s width, the allocator (heat sink) should be moved one heating element toward the radiator’s supply.
The installation height should remain the same (75%):
d. In the case of an odd number of heating elements and when it is not possible to install the allocator in the middle
of the radiator’s width, and when the mounting pin is located closer to the radiator’s supply, the allocator (heating
sink) is moved one heating element further. The installation height should remain the same (75%):
e. In the case of heaters with 20 or more elements 1 allocator should be installed. The rules of installation do not
change and remain the same as in the cases described above:

Installation of a heating cost allocator with remote sensor
Installation on towel warmers
The installation of the Hydroclima 2 allocator with a remote sensor is shown in the figures below. The cost allocator
should be mounted on the wall at a height of 1.5 meters. The heat sink with the sensor is mounted with the handle
at the level of 75% of the height and 50% of the width of the radiator, any deviations from the assumed mounting
position are the same as described in section “Installation” point 2.
The allocator (heat sink) should be installed at 75% of the radiator’s height, on the opposite collector from the power
supply, in accordance with the figures below. The cost allocator should be mounted on a vertical profile (welding or
gluing), if the profile is not available or the round allocator should be mounted horizontally on the ladders next to the
main collector with the use of grips.

7
HYDROCLIMA 2 - User Manual
Installation on tubular radiators
The allocator (heat sink) should be glued to the radiator on a straight segment without any ribs to ensure the largest
possible contact surface between the radiator and the heat sink.
In the case of heaters
with more elements the
installation method is a
combination of the above
methods.
. In the case of a single-element radiator the allocator should be installed (before the ribbing) from the side of the
supply vertically or (if the radiator’s diameter is small) horizontally. An example of such an installation is presented
below.
b. In the case of a 2-element radiator the allocator (heat sink) should be installed in the middle of the length of the
elements’ connection. An example of such an installation is presented below.
c. In the case of a 3-element radiator the allocator (heat sink) should be installed in the middle of the length of the
connection of the first two elements from the side of the supply. An example of such an installation is presented
below.
d. In the case of a 4-element radiator the allocator (heat sink) should be installed in the middle of the length of the
first and third elements connection from the side of the supply. An example of such an installation is presented
below.

Installation techniques
Installation with mounting brackets is the most common type of allocator installation. It is important to match the type
and size of the brackets to the radiator.
The installation itself is relatively simple. It involves the preliminary selection of the installation location according to
the guidelines presented above, followed by inserting the mounting bracket between the ribs/pipes of the radiator and
finally tightening the screws securing the heat sink.
The tightening torque value should be sufficiently high to prevent the allocator from being dislocated through being
“knocked down” or rotating. Using too much force can cause irreversible damage by bending the mounting bracket.
After tightening the screws you must secure the allocator with a seal at the bottom.
The below table presents all the installation parts:

Welding
1. Ensure the spacing between the electrodes is in line with the spacing of the allocator heat sink holes (40 mm).
2. Gently remove the paint from the radiator in the pins mounting area.
3. Degrease, for instance using a solvent, the areas on which the welded connection will be made.
6. Mount the heat sink on the pins.
4. Perform the weld according to the device’s guidelines.
7. Using the dedicated M3 (BRR 6) nut and the BRR 7 driver, secure the heat sink to the radiator.
8. Place the allocator on the heat sink.
9. Close the allocator with a seal at the bottom.
5. Adjust the pin length to the depth of the water channels.
CAUTION: Welding must be done between the water channels. Improper welding can permanently damage
the radiator.
CAUTION: Improper preparation of the welding surface or incorrect welding technique will result in the
damage of the connection. This often causes permanent damage to the radiator. You should
also pay attention to the quality of the pin. It can also result in unrepairable radiator defect.
It is recommended to issue prior notice to the tenants and secure items in the immediate
surroundings of the heaters.
CAUTION: Welding may be used, for instance, in the case of panel heaters or ribbed heaters.
