PROMATIC SGC Solar controllers 15
PROMATIC SGC Solar controllers HIGHLIGHTS ycontrol of up to 65 different hydraulic schemes. ymeasurement and display of gained energy. ysupport for electronic pumps (ErP). yremote control via SeltronHome platform. yoverheating and frost protection. PROMATIC SGC is a modern and powerful controller designed for demanding hydraulic systems. Effectiveness and universality of SGC controller is achieved with a built-in 0-10 V and PWM control of the solar circulation pump and the possibility to select between many different pre-set hydraulic schemes. For hydraulic schemes with two storage tanks, different loading strategies are available for optimal usage of the solar energy. The unused output can be freely programmed. PROMATIC SGC solar controllers control speed of solar circulation pump and keep constant temperature difference between solar panels and d. h. w. storage tank. This way the maximum efficiency of solar systems can be achieved. SGC solar controllers are performing also a variety of other control and logic functions to ensure an effective operation of many hydraulic systems with solar panels and other energy sources. Integrated solution Seltron simplicity adds a unique and easy note to the controller at start up and use. The 14-language support, simulation of the temperature sensors, graphical presentation of measured temperatures and gained energy offers to user even greater comfort and oversight of the solar system. Large illuminated graphical display allows a clear demonstration of the system operation and all other data. 16
SIMPLICITY SOLUTION SELTRONHOME USER FUNCTIONS Provide additional comfort and benefits when using the controller. One time domestic hot water warming The function switches on the water heating instantly. PROMATIC SGC controllers can be connected into the SeltronHome environment for a comprehensive remote control and operation regulation. Remote access is provided by the Clausius application for the end users and the Kelvin application for installers and servicemen. SETUP WIZARD Holiday mode for the solar system Holiday mode activates cooling down of the storage tank to minimum temperature during night time. Cooling is carried out through solar collectors. Anti-legionella program * The controller ensures the medium is bacteriafree by periodically heating water to 60 C. The controller leads you in 2- steps through the first commissioning; all other parameters are pre-set. SOLAR SYSTEM PROTECTION SYSTEM SIMULATION The controller has built-in mechanisms that protect solar panels as well as medium and heat storages against overheating or freezing. The simulation program is a special function which allows temperature sensor simulation, and thereby enables the user to test the system operation. INTERACTIVE HELP Fast and easy access to short manuals, notifications, warnings, software version, etc. PC INTERFACE Through dedicated USB inverter the PROMATIC SGC solar controller can be connected to a PC. The accompanying Selcontrol software allows setting and monitoring of controller operation using a PC. The solution also operates in the SeltronHome environment. * The above functions are available only by schemes with oil boiler, electric heather or heat pump. 17

OVERVIEW OF GAINED ENERGY SIMPLE CONTROLLER SETTING AT THE FIRST BOOT SGC controllers provide rough and precise measurement of the gained solar energy. To obtain a rough measurement, the maximum media flow reading from a mechanical gauge should be input into the controller settings. For precise energy measurement the flowmeter with impulse generator or vortex flow sensor VFS should be installed in the solar circuit. At the first boot the controller requires only two-step setting.
