The SC SUN 300 is a separation module incorporating a plate heat exchanger used in systems where energy is supplied
to two hot water buffer storage cylinders – or at two different heights to a single buffer cylinder – by a solar heating system
equipped with arrays of collectors. The electronic control system governs the revolutions (0-10 V speed control function)
of the high efficiency pumps on the primary and secondary circuits so as to ensure optimum exploitation and manage-
ment of the energy produced. The controller is also designed to allow remote control of the system by way of an Ethernet
port, save system-related operating data to an SD card, and report any irregular or abnormal events that may occur.
The primary circuit is equipped with an electronic flow meter (Vortex flow sensor) displaying the flow rate and allowing
computation of the amount of heat exchanged.

    - Any work required on electrical connections must be entrusted to an expert service technician. - Water circulating inside the SC SUN 300 module may be very hot and highly pressurised. Before the module is disassem- bled for whatever reason, the system should be drained of water, and the shut-off valves securely closed.

  • Page 10: Installation

    INSTALLATION HANDLING The responsibilities of the user include providing the equipment needed to handle and unload the module, checking the number of items delivered, and verifying the integrity of the material. The module is positioned on a pallet; use only a transpallet truck for handling purposes and fix the pallet securely, bearing in mind that the module will be at risk of tipping over if not restrained, given its weight and high centre of gravity.
  • Page 11 To ensure correct operation of the module, the following parameters must be observed for each of the components indi- cated: Deviation from these specific values could result in the SC SUN 300 being damaged, and consequently invalidate the manufacturer’s warranty.

  • Page 12: Filling Procedure

    START-UP The system must be filled and started up by an authorised specialist company. Technicians overseeing the procedure must test the operation and leak-tightness of the entire system, including factory-assembled components. The operation of the safety valve must be tested at regular intervals. It is recommended that the system be serviced annually by a spe- cialist company.

  • Page 13: Warranty And Liability

  • Page 24 6.3.1 Modes The following speed modes can be set: Off: no speed control whatever. The connected pump is activated or deactivated at full speed. Mode M1: following the purge time, the controller activates the maximum speed setting. If the difference in temperature ΔT between the reference sensors (collector and storage cylinder) is less than the setting, the speed will be reduced by one stage once the control time has elapsed.
  • Page 25 6.3.7 Minimum speed This is where the minimum speed of the pump at relay R1 is set. During the setting procedure, the pump runs at the se- lected speed so that the flow rate can be determined. Settings range: from “J.14.6 – Speed when On” to maximum speed minus 5% / Default: see table. 6.3.8 Setpoint This value is the control setpoint.
