Use The device comprises of 1 RDH100RF (transmitter) and 1 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.
Commissioning notes Parameter list Parameter Description Factory setting Setting range Remark P01 Control behavior PID slow (4) 0 = 2P, 1.0 K 1 = 2P, 0.5 K 2 = PID fast 4 = PID slow P02 Maximum temperature range 30 °C P03…30 °C Limit of comfort and economy setpoint P03 Minimum temperature range 5 °C 5 °C…P02 Limit of comfort and economy setpoint End Exit parameter setting Parameter setting The parameter setting remains in non-volatile memory and is not erased when the battery is removed.

Display The digital display shows the current room temperature and the comfort temperature setpoint. When the heating output is active, the triangle symbol is displayed.
Elements 1 Display of the room temperature in °C / °F 2 Indicates a request for heating 3 Temperature setting knob 4 Battery compartment 5 Comfort temperature setpoint 6 RF TEST Indicates RF signal test Indicates low battery power; replace batteries 7 The receiver is located in a plastic housing with LEDs and buttons. 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. Example B: Faulty connection between sender and receiver Press the OVERRIDE button to permanently override the value.
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 A6V10974421.) 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.
