The RDE10... provides normal operation and, optionally, energy saving mode or OFF.
The difference between normal operation and energy saving mode is only the room
temperature setpoint. The changeover between the operating modes can be made
either automatically according to the 7-day time switch or manually with the operating
mode selector.

Display
The digital display shows the actual room temperature, the time of day, the weekday,
the current switching pattern and the symbol of the operating mode currently active.
The switching pattern shows normal operation as a double bar and energy saving
mode as a single bar with a flashing time pointer. When the heating output is activated,
the triangle symbol appears.

In the event of a power failure, the setpoints and the information required for operating
mode changeover are retained for 3 minutes. This is enough to cope with power failures of short duration (with RDE10) or when changing the batteries (with RDE10.1).

Mechanical design
The unit consists of two parts:
• A plastic housing with digital display, which accommodates the electronics, the
operating elements and the built-in room temperatures sensor
• A mounting base
The housing engages in the mounting base and snaps on.
The base carries the screw terminals.

Change of batteries
(only with batterypowered versions)
Reset
The room temperature controller should be mounted in a location where the air temperature can be measured 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 unit can be fitted to a recessed conduit box.
• Only authorized staff may open the controller.
Caution: AC 230 V!
• The cables used must satisfy the insulation requirements with regard to mains
potential
When mounting the unit, fix the baseplate first. Then, make the electrical connections
and fit and secure the cover (also refer to separate 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.
The controller is maintenance-free.
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

If the battery symbol appears, the battery power is almost exhausted and the batteries
should be replaced.
