Essential recommendations for the correct operation of the system
• Low temperature sensor is not shown here, but make sure to install one to control the
circuit (using the additional wiring made available in the optional wiring kit).
• Low temperature cut-out thermostat is not shown here, but make sure to install one to
protect the low temperature circuit (to be connected to X20 terminal, ref. 14 on Prestige
24-32 Solo/Excellence wiring diagram).
