139 Remote Control: it can be installed in place of 72 to manage the request of the 1st zone (direct)
300 Burner On indication (voltage-free output): the example shows the connection of an hour counter at 230Vac
301 Fault indication (voltage-free contact output): the example shows the connection of a lamp at 230Vac
302 Remote reset input (230Vac): the example shows the connection of a double-pole switch at 230Vac, allowing
the resetting of a block type fault
357 Fault indication (230Vac): the example shows the connection of a lamp at 230Vac
Two mixed heating circuits, one direct heating circuit and one DHW circuit with
circulating pump
- Schematic diagram
The zone control card FZ4B can manage different types of systems. An example is given.
Use diverter valves with 3 wires:
- OPENING PHASE 230V
- CLOSING PHASE 230V
- NEUTRAL
with switching times (from all closed to all open) of not more than 180 seconds.
