14.1 CONNECTING THE PUMPS

Turn the control box downward to access terminal boards M1 and M3 used for the electrical connections by removing the protective covers (see figure 12).

Terminals M1 a – b: connection of the primary loop pump for the heating system (PLP)

Check the correct size and rating of the pump by referring to its hydraulic resistance table.

Terminals M3 11 – 12: connection for heating pump (P1)

Terminals M3 13 – 14: connection for hot water tank pump (PDHW)

The electrical specifications of the pump must be as follows:

230 V AC; 50 Hz; 1 A max; cos φ > 0.8.

If the specifications of the installed pump are different, a relay must be wired between the boiler control circuit board and the pump.

It is advisable not to adopt any electrical connection other than those described.
