Nothing special if you control your flow of water.

The outlet temperature will depend of water flow.The maximum water temperature at the condenser outlet must not be higher than values reported on operating limits of heat pump producer. In the event of higher temperatures the safety devices will trip causing the unit to shut down. If you can avoid triggering the safety devices, than nothing important will happen.

thanks for the quick response.
if i understand correctly, if i add some
more coolant R407c (biger condenser) the system will operate normally. Thanks again.

You are not understanding this correctly.
Refrigerant should be charged by subcooling (for R407C is usually 7K-9K or even more if piping pressure drop is high) at condenser outlet WHEN unit is near set-point and condensation saturation temperature is at design temperature (usually at 40°C).
You cannot add SOME amount. It need to be as described.
