Use The device comprises with 1 x RDJ100RF (transmitter) and RCR100/433 (receiver), is used to control the room temperature in heating systems.
Control behaviour (P01) The factory setting for control is “PID slow”, ideal for most heating systems.
Operating modes The device has the following modes: Automatic, Comfort, Energy saving and Frost protection. Move the operating mode slider to the respective position to select another operating mode. Automatic mode Automatic mode is active when symbol is displayed. The device operates as the selected 24-hour time program. Comfort mode Comfort mode is active when symbol is displayed.
Parameter setting mode 1. Press LEARN on the rear for 5 seconds until “P01” appears. 2. Press advance button, the parameter value on the second line flashes and is ready for adjustment. 3. Adjust the parameter using setting knob. 4. Press advance button once to confirm the setting. 5. Rotate the setting knob clockwise to next parameter and repeat steps 2 to 4. 6. Exit parameter setting mode by rotating the setting knob clockwise to “End” and pressing advance button once.
The service interval reminder can be enabled and reset by a service professional.

The transmitter is located in a plastic housing. Two buttons are visible on the rear when removing the baseplate. OVERRIDE Override allows for temporarily overriding the active value from the sender. Override responds differently depending on the radio connection (normal or fault). Example A: Normal connection between sender and receiver Press the OVERRIDE button to overwrite the value for ca. 14 minutes. The value then returns to the setpoint.
Notes Mounting When mounting the transmitter, attach the baseplate first. You need to mount the transmitter on a flat wall. (For details, refer to the separate mounting instructions A6V10974424.) The transmitter comes with a fold-out stand and may be used as a “mobile” device. Mounting the receiver does not require a baseplate. Connect the electrical connections first and then fit and secure the receiver in compliance with local regulations.
Disposal The device is considered an electronic device for disposal in accordance with the European Guidelines and may not be disposed of as domestic garbage. ● Dispose of the device through channels provided for this purpose. ● Comply with all local and currently applicable laws and regulations. ● Dispose of empty batteries in designated collection points.
