2.5 Connection to an external tank for domestic hot water production
Connection with circulating pump
The unit's electronic board is arranged for managing an external storage tank for domestic hot water production. Carry
out the plumbing connections according to the diagram fig. 9 (pumps and non-return valves must be supplied separate-
ly). Carry out the electrical connections as shown in the wiring diagram (see fig. 17). A FERROLI probe must be used.
At the next lighting, the boiler control system detects the hot water tank probe and automatically configures the DHW
function, activating the display and relevant controls.
