Two options are available to actuate the EREBATMheat pump: - An easily adjustable and economic silent mode reduces ● User interface WUI the compressor speed. ● ModBus protocol - The R-410A refrigerant is easier to use than other fluids. User Interface WUI NHC Control NHC control associate with compressor and fan variable frequency driver combines intelligence with operating simplicity. The control constantly monitors all machine parameters and precisely manages the operation of compressor, expansion devices, fans and of the water heat exchanger water pump for optimum energy efficiency. ■ Ease-of-use This interface can be installed up to 50 m away. It is connected to the NHC control using4 H07RN-F 0.75 mm cables.2 - NHC control can be associated with a new User interface (WUI) which allow an easy access to the configuration The WUI has an internal sensor to measure the room parameters (frequency compressor, refrigerant circuit temperature. temperature, sets points, air temp, entering water temp, Regulation can be based on the room air temperature. alarm report…). ■ Modbus - This user interface is also very intuitive in its use. It allowsDirect access with Modbus connection to set, configure and reading and easy selection of the operating mode. The monitor the EREBATMHe unit. functions are represented by icons on the LCD backlit screen. To facilitate the use of this interface, 3 levels of access are available: end user, installer and factory. 314 314 CATALOGUE 2021
