Operating modes
The RDE10.1DHW provides auto, normal operation, energy saving (or OFF) or frost
protection mode. The difference between normal operation and energy saving mode is
merely the room temperature setpoint. The changeover from normal operation to en-
ergy saving or frost protection mode, or vice versa, is made by pressing a button.
In auto mode changeover between operating modes is accomplished automatically
according to the 7-day switching pattern.
Normal operation When normal operation is activated, symbol appears on the display. The setpoint
can be readjusted by pressing buttons , +and -.
Energy saving or OFF When energy saving mode is activated, symbol appears on the display. The setpoint
can be readjusted by pressing buttons , +and -.
In energy saving mode, the unit can also be switched to OFF. This is accomplished by
selecting a setpoint of 5 °C and then keeping button -depressed for 4 seconds. In
that case, symbol does not appear.
When frost protection mode is activated, symbol appears on the display.
Frost protection
7-day time switch The changeover between “normal” and “energy saving” temperature setpoints can take
place either automatically ( ) or manually ( , ), depending on the selection of the
operating mode.
When pressing the operating mode button until appears on the display, changeover
will take place automatically according to the selected switching pattern. A specific
switching pattern can be selected for every weekday.
Factory setting: Day(s) Normal operation Energy saving mode
Mo (1) – Fr (5) 6:00 – 8:00 h and
17:00 – 22:00 h 22:00 – 6:00 h and
08:00 – 17:00 h
Sa (6) – Su (7) 7:00 – 22:00 h 22:00 – 7:00 h
The current setpoint can be temporarily readjusted by pressing buttons +and -. The
setpoint will then be reset to its initial value the next time automatic or manual change-
over takes place.
When the operating mode button is set to or , the controller will maintain normal
operation or energy saving mode respectively.
DHW mode The RDE10.1DHW features independent control of DHW.

Display The digital display shows the actual room temperature, the time of day, the weekday,
the current switching pattern for heating, the switching pattern for DHW, and the symbol
of the operating mode currently active. When the heating output is activated, the trian-
gle symbol appears.
Display of the switching pattern is split up in upper and lower row.
When the segment is displayed and flashing, the DHW output is activated. When no
segment is displayed, the DHW output is deactivated.

Notes
The room temperature controller should be mounted in a location where the air tem-
perature can be acquired as accurately as possible without getting adversely affected
by direct solar radiation or other heat or refrigeration sources.
Mounting height is about 1.5 m above the floor.
The controller can be fitted to a recessed conduit box.
•Only authorized staff may open the unit.
Caution: AC 230 V!
•The cables used must satisfy the insulation requirements with regard to mains
potential
Mounting, installa-
tions and commis-
sioning
When mounting the controller, fix the base first. Then, make the electrical connections
and fit and secure the cover (also refer to the relevant Mounting Instructions).
The controller must be mounted on a flat wall and in compliance with local regulations.
If there are thermostatic radiator valves in the reference room, they must be set to their
fully open position.
Maintenance The controller is maintenance-free.
Sensor calibration If the temperature on the display does not agree with the room temperature effectively
measured, the temperature sensor can be recalibrated. For that purpose, both buttons
+and must be pressed simultaneously for 3 seconds. Then, the temperature
displayed can be changed by a maximum of +/- 3 K by pressing the +and -buttons.
5 seconds after the last push of a button, the controller will automatically return to the
normal operating state.
