The RDH10RF provides room temperature control only.
The digital display shows the actual room temperature and the comfort temperature
setpoint. When the heating output is active, the triangle symbol appears.
When taking out the batteries, the setpoints and the information required for operating
mode changeover are retained for maximum 2 minutes.

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. The baseplate carries the screw
terminals. 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
acquired as accurately as possible without getting adversely affected by direct solar
radiation or other heat or refrigeration sources.
The controller can also be used in a portable manner. It features a fold-out stand allow-
ing it to be placed on a horizontal surface such as a bedside table.
Mounting height is about 1.5 m above the floor.
The unit can be fitted to a recessed conduit box.

When mounting the controller, fix the baseplate first. The receiver does not require a
baseplate. Make the electrical connections and fit and secure the receiver (also refer to
the separate mounting instructions).
Mount the controller on a flat wall and in compliance with local regulations.
If there are thermostatic radiator valves in the reference room, set them to their fully
open position.
Controller and receiver are maintenance-free.
If battery symbol appears, the batteries are almost exhausted and must be re-
placed.
To reset the controller, press both the Test and Learn buttons on the rear of the unit.
To reset the receiver, press the RESET button on the unit front.
All individual settings are then reset to their default values.
