BPZ:RRV912 RRV912 A
RRV912 Heating circuit controller, 2 heating circuits
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. underoor 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)
