Wireless central heating pump controller AURATON S03 RT The AURATON S03 RT controller is tended for wireless control of a central heating (CH) pump. Before you start using the controller, please read this instruction carefully.

APPLICATION AURATON S03 RT is intended for automatically switching on and off circula- tion pumps depending on the temperature. The controller-pump assembly forces the water to circulate in the central heating system with a coal-fired boiler or a gas boiler. The controller’s sensor measures the temperature of the water on the supply side of the CH system.
Description of the controller On the front part of the enclosure there is a backlit LCD display and four function buttons. an LCD display a temperature increase button a confirmation or controller on/off button a button for the reduction a temperature of the programmed decrease button pump shutdown temperature...

Display 1. Temperature In the normal operation mode, the controller displays the temperature in the room where it is installed. 2. Discharged battery ( ) The indicator is displayed when the permissible minimum battery voltage level is exceeded. The battery must then be replaced as soon as possible. NOTE: In order to maintain the controller settings, the battery replacement should take not more than 30 seconds.

3. AntyStop mode activation indicator This mode prevents seizing of the rotor of an unused pump. 4. Temperature unit ( °C ) This indicates that the temperature is displayed in degrees Celsius. 5. Activated pump indicator ( A pictogram that indicates the operating status of the pump. It is displayed when the controlled device is switched on.

Installation/replacement of batteries The battery compartment can be found inside the controller, on the front part of the enclosure. In order to install the batteries, take off the enclosure. battery compartment 2 x AAA 1,5 V batteries Put two 1.5 V AAA batteries inside the battery compartment, paying attention to the polarity of the batteries.
External temperature sensor External Terminal block temperature sensor As a standard, after the battery is put in, the controller without a sensor connected displays the temperature from the internal temperature sensor. When the external temperature sensor is connected, the controller automat- ically reads the values measured by that sensor.
If devices with higher power are connected, the cables should be replaced with ones of appropriate cross-sections. NOTE: When installing an AURATON RT receiver, make sure that the power supply is switched off. The receiver should be installed by a profes- sional.

1. Take off the cover of the front part of the AURATON RT receiver by unscrew- ing the screws half way out. 2. Connect the heating device to the ter- minals of the control connection of the AURATON RT receiver. Follow the ser- vice instruction of the heating device.

3. In the marked locations, drill holes with diameters appropriate for the diameters of the enclosed wall plugs (5 mm). 4. Put the wall plugs in the drilled holes. 5. Fasten the AURATON RT receiver to the wall using screws so that the receiver is well fastened. Note: If the wall is wooden, there is no need to use wall plugs.

Switching the controller on for the first time After the batteries are properly installed in the battery compartment, the LCD display shows all segments for one second (a dis- play test) and then it shows the software version. After a moment, the current temperature in the room is displayed.

Switching the “AntyStop” mode on/off In order to switch the AntyStop mode on, press and hold the button pressed for 3 seconds. The display shows (the function is active). The AntyStop mode prevents seizing of the rotor of an unused pump. Also, a built in processor starts the pump every 14 days for 30 seconds after the heating season is over.
Additional functions • After batteries are installed, the controller displays the temperature from the external temperature sensor. • When the external sensor is connected (the terminal block is located under the enclosure), the controller automatically takes the readings from that sensor. •...
