RF-based heating circuit controller for up to 2 heating circuits and DHW heating.
In operation, the RRV912 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)
Heating circuit control with 2- or 3-position actuators
2 universal relay outputs, 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
1 universal output DC 0...10 V for forwarding the heat / cooling demand signal
RF communication based on KNX standard (868 MHz, bidirectional)
