RRV918 - Synco Living, Heating Circuit Controller, RRV918

EAN: 7612914029737 - manufacturer-number: RRV918 - Synco living - Heating Circuit Controller + RF-controlled heating circuit controller for up to 8 heating circuits + RF communication based on KNX standard (868 MHz, bidirectional) + Connection facility for up to eight 2-position actuators + Mains-powered AC 230 V + 1 universal relay output + 1 universal input Use: + For integration into the Siemens Synco 900 system + Suited for use in heating plant  , ,- With central heat 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-position actuators + Universal relay output, e.g. for control of the apartment pump, DHW heating, or fan speeds + Universal input, e.g. for connection of a DHW temperature sensor or an alarm Equipment combinations: The RRV918 heating circuit controller is designed for use with the Siemens Synco 900 system. For more detailed information about equipment combinations, refer to the Data Sheet covering the central apartment unit (CE1N2707en). Scope of delivery: The RRV918 is supplied complete with Mounting Instructions. Product documentation: The Operating and Commissioning Instructions for the RRV918 are contained in the product documentation of the central apartment unit. Functions: Main function: In operation, the RRV918 maintains the required room temperature of the individual heating circuits. The central apartment unit delivers the relevant data via RF. Universal relay output: The universal relay output can be used to control different types of devices. Release is controlled via the central apartment unit and delivered via RF.[1] Universal input: The universal input is used for connection of the DHW temperature sensor, for example. The data are forwarded to the central apartment unit via RF.

Parallel operation: Several heating circuits can be assigned to one room and, therefore, operated in parallel. In that case, the first heating circuit ensures the actual room control and, at the same time, controls the other assigned heating circuits. Antilime function: The antilime function is triggered by the central apartment unit. When receiving an antilime command, the heating circuit valve will be fully opened and then closed again. When the antilime function is completed, the valve will return to the previous control position. Summer operation: Summer operation is triggered by the central apartment unit. When receiving a command to start summer operation, the heating circuit valve will be opened or closed, depending on the position predefined by the central apartment unit. If the antilime function is activated in summer operation, it will be performed. When completed, the control loops will resume summer operation. Window airing: The window airing function is triggered by the central apartment unit. The function interferes in the control process in a way that overheating of the room will be avoided both during and after the window airing time. Frost protection for the room: Frost protection for the room becomes active if the room temperature drops below the frost protection setpoint. It remains active until the room temperature returns to a level 1 K above the frost protection setpoint. Binding: The binding of the first selected channel is used by the RRV918 to sign on at the central apartment unit, thus ensuring integration into the RF system. Then, the other channels can be assigned to other rooms or function groups. The binding process is triggered via the multifunction button and indic - RRV918
