Filling Storage Tank Circuit (System With Flowsensor) - Rotex Solaris RPS3 P2 Operating And Installation Manual

4 x Start-up and taking out of service

4.1.3 Filling storage tank circuit (system with FlowSensor)

1. Filling the hot water storage tank:
• Fill the heat exchanger for domestic water.
• Fill buffer storage volume via the filling and draining cock (accessory
• Close the filling and draining cock (accessory
2. Switch on Solaris RPS3 P2 control and pump unit (initialisation phase begins).
3. After completing the initialisation phase (temperature display) you must bleed the system by pressing the two arrow keys
simultaneously (starting manual mode).
4. Check the entire system for leaky joints (in the building and on the roof). Repair any leaks found.
5. Switch off Solaris RPS3 P2 control and pump unit.
6. Check the filling level in the hot water storage tank.
7. Only if the water level in the hot water storage tank is not close to the fill level:
• Switch on Solaris RPS3 P2 control and pump unit again (initialisation phase begins).
• When the initialising phase is finished (temperature display), you can start the manual operating mode by simultaneously
• Measure the time until the inflow is heated at the plate heat exchanger.
• Set the measured time plus 5 s in the parameter "Time PsE" (see chapter 5.3.6).
• Start manual operation again by pressing the two arrow keys simultaneously.
• Measure the time during which the storage tank circuit is completely filled. The filling process is complete when no air
8. Switch Solaris RPS3 P2 control and pump unit to Automatic mode by pressing both arrow keys down at the same time or
by performing another switch on/switch off. The system is now ready for operation.
9. Only when the Solaris RPS3 P2 control and pump unit is connected to two domestic hot water storage tanks via the
connection cable (storage tank extension kit CON SX):
– The measured common flow in the solar inflow must be evenly distributed over both hot water storage tanks. We

noise can be heard and a stable value for the flow is displayed (actuate "Flow" measuring point with arrow keys).
The flow of the solar panel circuit can be checked at the flow display of the ROTEX RDS1 pressure station
(settings see tab. 4-2).
If a heat meter is installed in the system, the flow can be set based on the heat meter reading (settings
see tab. 4-2).
