Functions

The controller acquires the room temperature with its integrated sensor and maintains

the setpoint by delivering control commands. The switching differential is 1 K.

Operating modes

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.

When normal operation is activated, symbol “ “ appears on the display. The setpoint

can be readjusted by pressing buttons , +and -.

When energy saving mode is activated, symbol “ “ appears on the display. The set-

point 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.

The changeover between the operating modes can take place either automatically

() or manually ( , ), depending on the position of the operating mode selector.

When the operating mode selector is in position “ ”, changeover will take place

automatically according to the selected switching pattern. For every weekday, a specific

switching pattern can be selected.

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 auto-

matic or manual changeover takes place.

When the operating mode selector is set to” “ or “ “, the RDE10... will maintain

normal operation or energy saving mode respectively.

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.

Automatic changeover according Normal operation Energy saving mode

to the switching pattern

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 fail-

ures 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.

Notes

The room temperature controller should be mounted in a location where the air tem-

perature 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

+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.

Five seconds after the last push of a button, the controller will automatically return to

the normal operational statuses.

If the battery symbol appears, the battery power is almost exhausted and the batteries

should be replaced.

To reset, first press and hold the button , then press the two buttons

-simultane-

ously for 3 seconds. All individual settings will be reset to their standard values.
