Product description
■ Expansion module (only in conjunction with the Duplex Basic double-loop solar control unit)
■ For multiple-loop solar and heating systems
■ Large display with backlight for graphical indication of schematic, operating status, temperatures output and energy yield. Simple,
menu-based operation with 4 keys
■ 18 standard systems for 1 to 4 tanks and 1 or 2 collector arrays, systems with plate heat
exchanger also selectable
■ Selectable functional blocks can be connected to the outputs (difference, thermostat, plate heat exchanger and timer), especially to
control individual solar and heating systems and additional functions
■ Two weather-compensating heating circuits with remote control, domestic hot water priority circuit and auto summer mode
■
16 inputs and 10 outputs
■ 4 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.
■ 6 outputs (relays) for standard solar and heating pumps
■ 2 inputs for VFS flow sensors for measuring flow rate and temperature and for system control, as well as energy balancing (no
wearing parts).
■
2 inputs for RPS pressure sensors and for system control
■
Integrated, permanent storage of operating data, with graphical indication on display.
■ SD memory card slot: permanent, long-term recording for data logging 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 Data log kit 1510327
■ Protective functions (overheating protection for collector and system, frost protection, pump exercise function)
■ Sensor auto check and alarm.
■ Energy saving mode (automatic display standby mode after 15 mins.)
