BERETTA SC ACS 160 E - 225 E LOW ENERGY
The SC ACS 160 E - 225 E is a modern domestic hot water mixer that can use the heat accumulated in a storage cylin-
der to produce high volumes of domestic hot water. The unit incorporates an AISI 316 stainless steel brazed plate heat
exchanger.
The unit is controlled by an electric panel complete with a controller for the control and management of the functions of
all system components. The unit also permits the manual operation of all system components.
The heat exchanger's PRIMARY CIRCUIT comprises:
- A 3-way mixer valve for stabilising the temperature of incoming hot water
- 2 modulating pumps with 0-10 V control, installed in parallel
- A warning system with buzzer and LED indicator to warn of malfunctions in either of the 2 pumps
- A return line diverter valve that controls two separate storage cylinders or one storage cylinder with stratification control.
The heat exchanger's SECONDARY CIRCUIT, which delivers the domestic hot water comprises:
- An electronic meter for DHW temperature and flow control.
- A variable speed circulation pump.

Page 13: Control Panel
CONTROL PANEL - The controller incorporates an illuminated display with a synoptic that identifies the unit’s active functions and instant temperatures. - In the event of a pump malfunction (irrespective of whether the pump concerned is the primary or circulation pump) a warning buzzer sounds and a warning indicator appears, clearly identifying the faulty component and therefore faci- litating its replacement. -
Page 14: Preliminary Checks
PRELIMINARY CHECKS First of all, carefully remove the outer packing, then: - Remove the cardboard from around the unit. - Remove the protective nylon sheet. - Disassemble and remove the protective wooden cage using a lever to remove the staples. - Separate the mixer from the pallet by loosening the feet (1) and sliding off the bracket (2) securing the mixer to the pallet. - Page 15 installation, and according to best professional practices. WATER CONNECTIONS On completion of all transport or handling operations, always check the tightness of the water fitting ring nuts. Take particular care when connecting the unit to the water supply. When tightening a fitting, always hold the opposite fitting steady with a second tool to avoid damage.

Page 18: About The Controller
USE AND FUNCTIONS OF THE CONTROLLER ABOUT THE CONTROLLER The controller enables efficient use and operational control of the mixer system. Intelligent control of the two parallel primary circuit pumps optimises energy consumption and ensures 60% system perfor- mance even in the event of a malfunction in one of the pumps. - When DHW is drawn off, the controller switches on the first pump. - Page 19 Before the unit can be put into service, the controller must be fitted and default settings programmed by specialist personnel as required by local and national legislation and standards and in accordance with the safety precautions and instructions given in this manual. Specialist personnel working on the controller must read this manual before proceeding.

Factory settings (Menu 6.4) This function can be used to return all settings to their default values. Doing so will permanently erase all parameterization, analytical and other user-entered data from the controller. After use of this function, all controller settings will again assume the default values listed in the table at the end of this section.

Page 28: Troubleshooting
TROUBLESHOOTING The controller is a quality product and is designed and made to withstand many years of continuous use. The occurrence of an error is often to be attributed to a fault in another component of the system rather than in the controller itself. The following descriptions of certain errors and their causes should enable the installer and operator to avoid damage and to restart the system as quickly and as cheaply as possible. - Page 29 REPLACING THE CONTROLLER FUSE Repairs and maintenance must be entrusted exclu- sively to an expert service technician. Make sure that power has been disconnected from the control- ler before commencing any work on it. Use only the spare fuse supplied, or select a similar fuse with the following specifications: T2A 250V If the controller is connected to the power supply and does not come into operation, or the display remains blank, the...
