1. PRODUCT PRESENTATION
1.1 BRH units
This chapter contains general descriptions relative to the BRH family. Please refer to the specific sections of this bulletin for more detailed information.
BRH FF and BRH FFT are the ranges of water-cooled chillers running on R410A ecological gas. They comprise indoor units with scroll hermetic compressors, plate heat exchangers, circula-tion pump (models FF) and Full Floating technology.
1.2 Operate in respect of the environment
R-410A is an ecological gas because its high efficiency reduces electricity consumption and consequently CO2 emissions and because it does not damage the ozone layer (ODP = 0).
1.3 Full Floating control logic
The new generation controller uses Full Floating Technology to manage unit logic. This technology was specifically developed by Climaveneta to optimise control of condensation pressure, the system circulation pump (Floating Flow) and the adjustment setpoint (Floating Setpoint). This makes it possible to achieve the following benefits: extensive operating limits, performance improvement both in standard and in limit conditions and shorter plant set-up times.
1.4 Versatility
Thanks to their simplicity of installation, BRH units can satisfy all system and application requirements. They can be supplied without the hydronic unit (BRH FFT) or with integrated hydronic unit on board the unit (BRH FF). The latter, in fact, are fitted with circulation pump for the system and a modulating valve on the outlet circuit for condensation control, as well as protection logics for optimising system operation.
1.5 Ease of installation
All the BRH unit connections are located in the upper part of the units, thus simplifying installation operations. This feature also makes it possible to save space as the units can be positioned near the perimeter walls without compromising access to the internal components during maintenance.
1.6 Silent-running
The BRH units stand out for their silent running. The panelling, incorporating a layer of soundproofing made from high intermedi-ate density conoid sandwich material, give all the units such low noise levels as to allow them to be used in residential and com-mercial areas without the need to install them in plant rooms.
1.7 Energy savings
The working setpoint of BRH units can be managed according to the logics that best adapt to the severest application require-ments. The ECONOMY and COMFORT functions, in fact, can change the operating conditions of the machine in a fixed or dynamic way, without compromising system functionality and assuring maximum energy saving.
Introduction
Perfect functionality of Climaveneta units is guaranteed by ac-curate tests carried out along the productive process, and by final test of every unit at the end of the work cycle, as imposed by ISO9001.

3.2 Compressor start delayTwo functions have been introduced to avoid over-frequent compressor start-ups:- minimum delay after last stop 3 minutes.- minimum delay after last start 5 minutes.
3.3 System-side circulation pump (FF models)The electronic board has an output for managing the circulation pump. This is always active. The pump switches off 1 minute after the unit switches off (stand-by). After 1 minute of pump operation, when the water flow reaches full capacity, the water flow alarm functions are activated (differential pressure switch and flow switch).The FFT models (circulation pump not included) are provided contacts (on the electrical board terminal block) for the manage-ment of an external pump.
3.4 Modulating valveThe electronic board has a 0-10V output for the management of a 2-way modulating valve. The modulating valve is opened before the compressor starts and closed a few seconds after the compressor stops. When the compressor stops the valve remains closed.3.5 Antifreeze alarm The anti-freeze function is active even if the controller is on stand-by. To prevent the plate exchanger from breaking due to the water inside it freezing, the microprocessor blocks the com-pressor and starts the plate exchanger heater if the temperature detected by the temperature probe of the water leaving the exchanger is less than +4°C. This set anti-freeze temperature can only be changed by an authorised assistance centre and only after checking that there is an anti-freeze solution in the hydraulic circuit. If this alarm trips, it blocks the compressor and not the pump which remains active. To resume normal opera-tion, the temperature of the outlet water must rise by over +7°C. Reset is automatic. If the number of anti-freeze interventions is more than 3 in an hour, reset becomes manual.
3. ELECTRONIC CONTROLLERThe HSW12 device is the new Climaveneta controller for the management of air-cooled units. The new 4-digit display offers clear reading of the variables in play, while the 14 symbols give an immediate view of machine states for system diagnostics. The 4 keys can be used to navigate the tree menu, access to which is password-protected for maximum security.The controller integrates the Full Floating function which allows the units to be used even in the absence of inertial storage boil-ers. The algorithm, in fact, assures ideal operating conditions by modifying the control parameters, thus varying the speed of the system pump and the aperture of the outlet valve, as well as the temperature setpoint of the unit. The latter characteristic can be used to adapt operating conditions in order to reduce the frequency of compressor start-ups during the periods in which the heat demand from the rooms to condition is limited.As a result, the presence of inertial storage boilers becomes superfluous and it is therefore possible to eliminate the direct purchase and installation cost, thus limiting the size of the system.The electronics also incorporates a series of protection algo-rithms in order to prevent damage being done to the main system components. The most important include parameters concern-ing compressor start-up times in order to prevent over-frequent starting times (minimum delay after last stop and minimum delay after last start). To prevent the water inside the plate exchanger
from freezing and breaking it, the control electronics also blocks the compressor if the temperature of the water measured by the probe leaving the exchanger is lower than a protection setpoint (anti-freeze setpoint). There is also a water flow alarm activated by differential pressure switches installed standard on the unit, or by optional flow switches that can be added to the system during installation.Condensation control is managed by modulating the water flow through the exchanger on the outlet side by means of a 2-way modulating valve.There are also two energy-saving functions (ECONOMY and COMFORT) that manage a temperature setpoint either in a fixed way, or dynamically according to the temperature of the water produced on the system side. To enable this function, connect an additional temperature probe to the unit, position it in the external air (accessory) and also the relative configuration parameters of the control algorithm. This function can also be used to improve the level of comfort by continually optimising the ambient according to external environmental conditions.
3.1 Heat adjustmentTemperature adjustment is based on the water returning from the system. The setpoints refer to the temperature of the return water. The temperature of the delivery water depends on the difference between the inlet and the outlet water. This is gener-ally the rated difference of 5°C. The thermal head can change depending on the type of hydraulic system.The controller is fitted with Full Floating technology which, after the scanning period, optimises the water setpoint in relation to compressor operating time and water temperature.
