Final instructions for commissioning
The various parameters for the heat pump are pre-set in the factory.
These factory settings are suitable for the most common heating systems.
For other systems and situations, the parameters can be modified.
1. If necessary, deactivate the heat pump's domestic hot water mode.
2. Simulate a heat demand to start up heating mode.
3. Check start-up of the outdoor unit and the back-ups connected.
4. Check the flow rate in the installation in comparison to the minimum
flow rate.
5. Put the heat pump in shut-down/frost protection mode.
6. After about 10 minutes, vent the air in the heating system.
7. Check the hydraulic pressure on the user interface. If necessary, top
up the water level in the heating system.
8. Check the fouling level of the filter(s) inside and outside the heat
pump. If necessary, clean the filter(s).
9. Restart the heat pump and deactivate shutdown/frost protection mode
10. Explain how the system works to the users.
11. Hand over all manuals to the user.
