It has been designed a big terminal board (TB2) in order to allow the easy electrical connection which provide all the diffe-
rent possible congurations (3-way valve, water pumps, boiler...).
Additionally, in order to help with the electrical installation works, HITACHI offers the following specic documentation:
- Service Manual and Installation and Operation Manual: All the necessary information about how to perform the
electrical works (electrical installation, connection, dip switch setting, ...) is reected in these documents.
- Schematic label: The different possible connections to the terminal boards are indicated by means of a schematic
label with the gure corresponding at the required conguration (see previous gure).
- Big Electrical Wiring Diagram and Caution Label: There are two labels sticked on the rear side of the electrical
box cover for a quick refering when electrical works are required. So, installer can get easy and clear wiring un-

- Separated terminal boards. The TB1 is the power connection board, and the TB2 is the accessories connection
board, with an additional ground socket (position 14).
