Confirm by . • If possible, mount the receiver temporarily (e.g. using dual-sided adhesive tape) to try to identify the best possible location for RF reception. To do this, fully wire the RCR10/868 and close the front cover. • See Point "4 Test radio link / identify best RF reception location“. a) Switch on RCR10/868 b) Press the Test button on the rear or the REV24RF.. and place the unit in the best RF reception location. Test the radio link between the room controller and all connected receivers. On the RCR10/868, LED_2 flashes quickly. The test turns off automatically after 10 minutes or you can manually end it by pressing one of the following buttons: , or . c) The REV24RF.. shows the quality of the radio link to the connected RCR10/868. If more than one receiver is connected to the same REV24RF.., the display changes every 10 seconds from RCR 01 to RCR 02, etc.. Select the receiver with or . The selected receiver is tested continuously for 1 minute. d) REV24RF..: The greater the visible bar under numbers 0…9, the better the radio link. If the bar is below the number 0, radio link is not guaranteed. In this case, move the room controller to a different location and shorten the distance between the REV24RF.. and RCR10/868. Repeat the test until quality is sufficient. Insufficient Sufficient Good Very good e) RCR10/868: LED_1 also indicates the radio link quality: Red = Insufficient or no radio link Orange = Good Green = Very good f) If radio link quality is insufficient, shorten the distance between the REV24RF.. and RCR10/868.

Siemens Room temperature controller radio set REV24RF../SET CE1N2206en Building Technologies 24.04.2008 Press the override button on the receiver to manually override the relay. LED_1 flashes. Override is active for at least 15 minutes. Press again to remove manual override. If the room controller sends a control telegram within these 15 minutes, the telegram is suppressed and executed only after these 15 minutes. This function allows for testing the unit connected to the receiver. After expiration of manual override, the RCR10/868 immediately executes every control telegram received. In the even of errors (e.g. empty batteries), the room controller no longer sends control telegrams. Press the override button on the receiver to permanently turn on the connected unit. This function allows you to e.g. run the heating system even if the room controller is off. When the room controller resumes operation (e.g. after inserting new batteries), its control telegrams overwrite manual override. Synchronization takes max. 130 minutes. The receiver delivered with REV24RF../SET is connected to the controller at the factory. Manually connect RCR10/868 and REV24RF.. : a) On the RCR10/868 press the “Learn“ button for about 4 seconds: The blue LED_2 flashes slowly, learning mode is active. b) Also press the "Learn" button within 20 minutes on the REV24RF.. : The REV24RF.. now either shows confirmation that receiver (RCR 01, RCR02, etc.) is connected or that connection failed. Display on the RCR10/868: When connection is successful, the blue LED_2 briefly flashes quickly, and LED_1 goes from red to green. If connection failed, learning mode remains active: The blue LED_2 flashes slowly. c) You can connect max. 15 receivers to 1 room controller. For unique identification of each receiver, the REV24RF.. assigns a number to each RCR10/868 connected. The REV then displays this number after a successful learning process. • The error indication on the REV24RF.. can point out a radio issue to one of the connected receivers. Check the error message with . Check the receiver as needed. • LED_1 is red when the RCR10/868 receives a weak, garbled or no control telegram for about. 65 minutes. Check the display on the REV24RF.. for an error message. • As long as the RCR10/868 correctly receives the control telegrams, the receiver operates normal. If a control telegram is not received correctly, the relay remains in the position last switched. As soon as the RCR10/868 again receives a correct control telegram from the REV24RF.., the receiver resumes normal operation. • The relay switches off, if the RCR10/868 receives no or an incorrect control telegram from the REV24RF… This switches off the controlled unit. LED_1 is red. As soon as the RCR10/868 again receives a correct control telegram from the REV24RF.., the receiver resumes normal operation. • In the case of power interruption at the RCR10/868, the relay goes to OFF.
