cod. 3541D501 - Rev. 03 - 12/2013
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.
fig. 45
- Electrical connections
After installation, carry out the necessary electrical connections as shown on the wiring
diagram.
Then configure the controller as described in the specific section.

ISPESL safety devices (When required - not supplied)
To manage sliding temperature it is necessary to purchase the external probe accessory code 013018X0
If a hot water tank probe (not supplied) is used, it is necessary to purchase the NTC probe accessory code
1KWMA11W (2 mt.) or code 043005X0 (5 mt.)
If a hot water tank thermostat (not supplied) is used, it is necessary to purchase the kit accessory code
013017X0 (to be connected in place of the Hot Water Tank Probe)

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
