General Information

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.

Intended Use

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. Every heat cost allocator uses a specific algorithm to count the consumption units. Only devices of the same manufacturer and model can be installed in the same unit of cost.

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.
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.
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.
5. The installation height of the heat sink must be measured from the hole in the middle of the heat sink.
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.
7. Place the allocator on the heat sink.
8. Close the allocator with a seal at the bottom.
9. To ensure the heating cost calculation is correct, it is necessary to install all allocators of a given radiator at the same height.
10. When performing the installation or stocktaking of allocators, the rooms in which they are located should be described in clockwise order.

Installation on Radiator Heaters

The allocator (heat sink) should be installed using a properly selected mounting bracket. Please consult the following installation cases:

Case a: Even number of heating elements

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.

Case b: Even number of heating elements with middle mounting pin

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%).

Case c: Odd number of heating elements, not possible to install in middle width

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%).

Case d: Odd number of heating elements, mounting pin closer to supply

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 (heat sink) is moved one heating element further. The installation height should remain the same (75%).

Case e: Heaters with 20 or more elements

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

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.

Installation on Towel Warmers

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, the round allocator should be mounted horizontally on the ladders next to the main collector with the use of grips.

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.

Case a: Single-element radiator

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.

Case b: 2-element radiator

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.

Case c: 3-element radiator

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.

Case d: 4-element radiator

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.

In the case of heaters with more elements, the installation method is a combination of the above methods.

Installation Techniques

Mounting Brackets

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.

CAUTION! 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.

For more details on models and availability of brackets, contact B METERS sales department.

Gluing

1. Measure the heat sink installation points on the radiator according to “General Installation Rules”.
2. Before starting gluing, degrease and clean the gluing area on the radiator.
3. Apply around 3 cm strips of Loctite AA 330 glue (yellow tube) on contact points between the heat sink and the radiator.
4. Apply the SF 7386 activator to the glue strips.
5. Apply the quick-drying Loctite 454 glue (blue tube) in select spots before the Loctite AA 330 glue fully hardens and bonds with the activator (around 15 minutes).
6. Place the heat sink on the measured installation point and press for about a minute.
7. Place the allocator on the heat sink.
8. Close and secure the allocator with a seal at the bottom.

CAUTION: The glue bonding time can be longer if the radiator is cold.

Configuration

Programming and configuration of the device is carried out by radio, using an RFM-RX2 and BMetering software. To trigger the configuration procedure, the BMetering software must be properly configured:

• For the factory state of the allocator, press the button for < 1s.
• For an already configured allocator, press the button for > 5s, until the display shows the message “rF”. The method of configuration for the allocator has been described in the documentation concerning the BMetering software user manual.
