XHCC - System-Controller

The Xtra large controller for flexible regulation of complex heating systems

  • Attractive housing (H 228mm W 180mm D 53mm) with various installation possibilities
  • High-contrast, white illuminated large display with extensive full-text and graphic mode
  • Self-explanatory operation via 4 softkey entry keys
Connections:
  • 8 sensor inputs for Pt1000 temperature sensors
  • 2 sensor inputs for Grundfos VFS sensors for heat metering (flow and temperature measurement), alternatively pressure monitoring via Grundfos RPS sensor
  • Sensor expansion jack for 3 additional sensors
  • 2 outputs 0..10V or PWM signal for control of high efficiency pumps, large pumps and frequency converters
  • 2 switching outputs for speed control of standard pumps
  • 4 relay outputs mechanical 230VAC
  • 1 relay output potential free
  • Micro SD Memory Card Slot
  • Ethernet connection (optional)
  • Digital connection / bus system
Hydraulic variants:HCC 6

There are 6+ basic systems selectable which can be extended easily and flexibly by activating diverse additional functions via the unassigned relays.
