| SIEMENS RDD 10.0 Room Temperature Controller |
Use :
This is used for 2-position control with ON / OFF output for heating.
Operating modes: normal operation and energy saving mode Automatic operating mode change over as an option.
Typical applications: Apartments , Commercial spaces , Schools
For the control of the following pieces of equipment: Thermic valves or zone valves , Gas or oil burners , Fans , Pumps
Function :
The controller acquires the room temperature with its integrated sensor and maintains the setpoint by delivering control commands. The switching differential is 1 K.
Display : |
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
Mounting :
- When mounting the unit, fix the baseplate first. Then, make the electrical connections and fit and secure the cover .
- 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.
 |
| Mounting Instructions |
- 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.
Sensor calibration :
If the temperature on the display does not agree with the room temperature effectively measured, the temperature sensor can be re calibrated.
For that purpose, both buttons + and mode changeover button must be pressed simultaneously for 3 seconds.
Then, the temperature displayed can be changed by a maximum of +/- 3 Kelvin by pressing the + and - buttons.
Five seconds after the last push of a button, the controller will automatically return to the normal operational statuses.

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