Operating Instructions RDU...

RDU... – the temperature controller that allows you to easily set the room temperature you want. You have 2 choices. You can either rely on the factory settings or make adjustments that suit your individual needs.

Display Display of actual room temperature Cooling valve open Heating valve open Normal operation Energy saving mode Settings and operation Siemens 123.5°C Operating mode selector (RDU50.2) Heating mode, Off, cooling mode Buttons for setpoint adjustments Warmer / colder Adjustment of temperature setpoints Heat Off Cool

Changing from heating to cooling mode

	Automatic changeoverWith the RDU50.2, manual changeover modes selector from heating mode, Off to cooling mode.Off = out of operation.
	Display shows that the heating output is activeDisplay shows that the cooling output is active

Changing from normal operation to energy saving mode

Changeover from normal operation to energy saving mode takes place automatically via an external contact (window switch / remote operation switch, etc.). (Exception with type RDU50.2 in Off mode) Display shows normal operation. Display shows energy saving mode.

Energy saving mode

If you want to change the factory-set temperature setpoints (16 °C for heating and 28 °C for cooling), follow the procedure given below ("Changing the control parameters").Important:The setpoint of energy saving mode can be set to Off.This means that the controller is not active in energy saving mode and the parameter display shows Off.Risk of frost!

Are your rooms too warm or too cold?

Normal operation

The + / - buttons allow you to increase or decrease the current room temperature setpoint in steps of 0.5 °C. To do this, proceed as follows:

• Press or hence
  → The setpoint display starts flashing
• Press the buttons again to change the room temperature setpoint

10 seconds after the last press, the new temperature setpoint will automatically be stored. The display stops flashing.

Changing the control parameters

(To optimize the control performance, a number of control parameters can be adjusted. This can also be made during operation without opening the controller.

Do you want to change the control parameters of the heating and / or cooling setpoints in the normal or energy saving mode? Or do you want to increase / decrease the switching differential in heating and cooling mode?

Then, proceed as follows:

(For factory settings, see above under "Commissioning")

1. Normal operation mode
2. Press the + and - buttons simultaneously for a min. of 3 and a max. of 5 seconds. Release them and within 2 seconds, press the + button again for 3 seconds. The display will show 'P01'.

1. Select the required parameter by repeatedly pressing the + or - button:

1. Press the + and - buttons simultaneously, the current value of the selected parameter appears, which can be changed by repeatedly pressing the + or - button.
2. By pressing buttons + and - simultaneously again or 5 seconds after the last press of a button, the last parameter will be displayed again.
3. If you wish to display and change additional parameters, repeat steps 3 through 5.
4. 10 seconds after the last display or setting, all changes will be stored.

If the room temperature displayed by the controller does not agree with the temperature effectively measured, the temperature sensor can be recalibrated. For that purpose, parameter P07 must be changed

Proceed as described under "Changing the control parameters" and follow steps 1 through 3 to select parameter P07.

With step 4, the room temperature displayed can now be matched to the temperature effectively measured. Each push of the + or - button changes the temperature by + or - 0.5 °C up to a maximum of + / - 3 °C. With step 7, the recalibration is automatically stored 10 seconds after the last readjustment.
