In some cases, water pump of the YUTAKI unit is not sized for big heating installation
(small water pump). In this case, a hydraulic separator or buffer tank and secondary
water pump has to be used to ensure proper water pump dimensioning.
The boiler is congured in parallel with the heat pump. A hydraulic separator or buffer
tank has to be used to ensure proper hydraulic balancing. Additional Water pump (WP3)
and water sensor (Two3) are needed for boiler combination control (automatic added
when Boiler combination is enabled).
For more information refer to “Space water temperature control” chapter in Service
Manual.

- One power meter for all installation (IU+OU).
- Two separated power meters (one for IU and one for OU).
