- Remove X40 bridge in case of connection:
• Cascade and zone regulator;
• 0-10V signal;
• BMS;
• BUS OT;
• some types of central heating demand.
- For low-temperature zones, insert a safety thermostat in series with the relative zone pump.
- Make sure that the Openerm thermostat is compatible with the appliance.
- If the 0-10V input is enabled by means of the specic parameter, insert a 4,7 kohm resistance on terminals Y and Z.

N.B.: e new electronics of VICTRIX PRO V2 EU can now control up to 15 thermal modules in simple cascade! It can also
completely independently manage up to 2 zones of the thermal system (1 direct and 1 mixed, if any) and1 DHW production
circuit.
