A direct heating circuit and a DHW circuit with diverter valve (3-wire)
- Schematic diagram
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 90 seconds.

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)
