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.)
