The RDH10RF provides room temperature control only.
The digital display displays the actual room temperature and the comfort temperature
setpoint. The triangle symbol appears when the heating output is active.
Setpoints and information required for operating mode changeover are retained when
exchanging batteries. The values must be checked though.
Ordering
Please provide the name and product number when ordering: Room temperature controller RDH10RF/SET.

Mechanical design
The controller consists of 4 parts:
• Plastic housing with digital display accommodating the electronics, operating ele-
ments and built-in room temperature sensor
• Baseplate (mounting base)
• Removable battery compartment
• Fold-out stand
The housing engages in the baseplate and snaps on. There is a reset button on the
rear of the unit.

Notes
Mount the room temperature controller in a location where the air temperature can be
measured as accurately as possible without being adversely affected by direct solar
radiation or other sources of heat or cooling.
The controller is delivered with a fold-out stand and may be used as a "mobile" device
(Note: Pay attention to mounting location).
Mounting height is approximately 1.5 m above the floor.
The unit can be fitted to a recessed conduit box.
Fix the baseplate prior to mounting the controller. The receiver does not require a
baseplate. Connect the electrical connections and fit and secure the receiver in compliance with local regulations (also refer to the separate mounting instructions).
Mount the controller on a flat wall.
If there are thermostatic radiator valves in the reference room, set them to their fully
open position.
For commissioning please refer to the Operating Instruction CE1B3070xx
Controller and receiver are maintenance-free except for the controller battery.
If battery symbol appears, the batteries are almost empty and must be replaced.
Simultaneously press the TEST and LEARN buttons on the rear side of the controller to
reset it (reset function).
Simultaneously press the OVERRIDE and LEARN buttons to reset the receiver (reset
function).
All individual settings are reset to the default values.

Override allows for temporarily overwriting the active value from the sender.
Override responds differently depending on the radio connection (normal or fault).
Example A: Normal connection between sender and recipient
Press the OVERRIDE button to overwrite the value for ca. 14 minutes. The value
then returns to the setpoint.
Example B: Faulty connetion between sender and recipient
Press the OVERRIDE button to permanently overwrite the value. The value
returns to the setpoint after the connection between sender and recipient works
again.
