Heating circuit controller, 8 heating circuits
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)
