Heating circuit controller, 8 heating circuits

Stock no. BPZ:RRV918

Stock no. BPZ:RRV918

RF-based heating circuit controller for up to 8 heating circuits.

In operation, the RRV918 maintains the required room temperature of the individual heating circuits. The central apartment unit QAX9.. forwards the relevant data via RF.

  • Suited for use in heating and cooling plants

  • With central distributors (e.g. underfloor heating or soft steel piping system)

  • For use with motorized radiator valves (e.g. with sill covers)

  • Connection facility for up to eight 2-position actuators

  • 1 Universal relay output, e.g. for control of the room group pump and DHW heating

  • 1 Universal input, e.g. for connection of a DHW temperature sensor or an alarm

  • RF communication based on KNX standard (868 MHz, bidirectional)
