Duplex Basic double-loop solar control unit
Product description
- Duplex Basic double-loop solar control unit
- For double-loop solar and heating systems, with extra output for secondary heat source
- Large display with backlight for graphical indication of schematic, operating status, temperatures, output and energy yield
- Simple, menu-based operation with 4 keys
- 8 standard and 4 additional systems (solar, plate heat exchanger, heating circuit return boost, secondary heat source, cooling)
- 8 inputs and 3 outputs
- 2 outputs (Triac), with either phase control for electronic speed control of standard solar and heating pump or with PWM signal for speed controlled high-efficiency energy-saving pumps.
- 1 output (relay) for solar and heating pump or valve (secondary heat source or cooling control unit)
- Input for VFS flow sensors for measuring flow rate and temperature and for system control, as well as energy balancing (no wearing parts). Input for VPS pressure sensors, for system control
- Integrated, permanent storage of operating data, with graphical indication on display.
- SD memory card slot: permanent, long-term recording for datalogging of system parameters and operating data (temperatures, pump status, operating time, output and energy yield). Detailed evaluation on a PC (system monitoring, system configuration, energy yield for energy balancing).
- Order SD card and software separately – SD Datalog kit 1510327
- Protective functions (overheating protection for collector and system, frost protection, pump
- exercise function)
- Sensor monitoring and fault display
- Energy saving mode (automatic display standby mode after 15 minutes)
- Software update slot
