RRV912 / RRV918 heating circuit controllers or the RRV934 multi-controller. Antilime function The QAX910 can trigger the antilime function at regular intervals, aimed at prevent- ing valve plugs and pump impellers from seizing during longer off periods. The function ensures that the valve actuators will travel to the fully open and then to the fully closed position and that the pumps will be activated for short periods of time (valve kick). - Page 5 0% or 100% and the SSA955 radiator control actuators will be driven to the preselected valve positions. DHW charging / The QAX910 provides DHW control with the help of a specific DHW time switch. DHW control DHW heating is either enabled or disabled based on the temperature acquired by the DHW temperature sensor connected to the QAX910 or an RRV912 / RRV918 / RRV934.
