Multiplex expansion module
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 VPS 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 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)
- Energy saving mode (automatic display standby mode after 15 mins.)
- Software update slots for Duplex and Multiplex
