The RDE10.1DHW is used for the control of the room temperature in heating systems with independent control of DHW.
Typical applications
- Residential apartments
For the control of the following plant components and of DHW:
- Thermal valves or zone valves
- Gas or oil burners
- Fans
- Pumps
- Heat exchanger
- Continuous-flow water heater
- Small water heating systems

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, the symbol appears on the display. The set
point can be readjusted by pressing buttons and .
Energy saving or OFF
When energy saving mode is activated, the 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 the button depressed for 4 seconds. In that case, the symbol does not appear.
Frost protection
When frost protection mode is activated, the 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, the 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
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. The display of the switching pattern is split up into upper and lower rows.
Upper row with switching pattern for DHW control
When the segment is displayed and flashing, the DHW output is activated. When
no segment is displayed, the DHW output is deactivated.
Lower row with switching pattern for heating
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.
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. The 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 for the main 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. 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.
