5.2.1 Pump operation
During pump operation:
– Continuous measurement of the temperature difference between solar panels and return temperature and comparison
with selected parameter "Delta T on".
– Pumps switched on if this parameter is exceeded (e.g. return temperature equal to 40 °C and "Delta T on" equal to 15 K;
solar panel temperature >55 °C).
Î
If the FlowSensor measures a stable flow before expiry of this period, the solar system is in operating mode.
– With installed FlowSensor only: the pump control systems depending on the temperature difference between the Solaris
feed and return temperature.

Operating and display components for the R3P control systems
Due to continuous improvements for optimum use of the Solaris RPS3 P2 control and pump unit, the
Solaris R3P control has been fitted with an update function. Therefore, some functions described in this
chapter are applicable to specific software versions only. These functions are indicated separately by symbols.
Software updates to the Solaris R3P control may only be carried out by a ROTEX service technician.
The ROTEX solar system is operated fully-automatically throughout the year. The speed-controlled pump
operation is controlled by the Solaris R3P control systems. The operating and display components are shown
in image 5-1.
The power switch completely disconnects the Solaris R3P control systems from the mains voltage. Switching
on the power switch requires greater pressure on the button than pressing the operating buttons.
