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 energy 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.

Frost protection

When frost protection mode is activated, symbol appears on the display.

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:

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 changeover 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.

The following DHW operating modes can be selected:

Continuously ON: Symbol appears on the display
Continuously OFF: No symbol on the display
Auto: Symbol appears on the display, DHW is switched according to the selected switching pattern

Factory setting: Time switch for DHW

Day(s)	DHW control ON	DHW control OFF
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

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 triangle 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.

Upper row with switching pattern for DHW control

When the segment is displayed and flashing, the normal temperature setpoint is active. When no segment is displayed, the energy saving or frost protection temperature setpoint is active.

Lower row with switching pattern for heating

OFF mode and frost protection display

Backup

When taking out the batteries, the setpoints and the information required for operating mode changeover are memorized. However, the real time clock must be reset after the batteries are replaced.

Ordering

When ordering, please give name and type reference: Room temperature controller RDE10.1DHW.
Valve actuators are to be ordered as separate items.

Equipment combinations

Accessories

Mechanical design

The controller consists of 2 parts:

• Plastic housing with digital display, which accommodates the electronics, the operating elements and the built-in room temperature sensor
• 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 temperature 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.
  
  AC 230 V!
• The cables used must satisfy the insulation requirements with regard to mains potential

Mounting, installations and commissioning

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.

Change of batteries

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

Reset

To make a reset, first press and hold the button, then press the 2 buttons simultaneously for 3 seconds. All individual settings will be reset to their standard values.
