•
Connect the neutral wire (coloured blue) to the terminal marked with the letter “ N ”;
•
Connect the permanent live wire (coloured brown) to the terminal marked with the letter “ L ”;

The appliance MUST be supplied with a permanent live in order for the boiler’s protective functions to
operate correctly. These functions include frost protection, post-ventilation, pump overrun and pump
& 3-way valve inactivity protection. On first connection to the power supply, the appliance must be
switched on using the ON/OFF button on the control panel to activate all of the above protective
features. The appliance can then be switched off but the protective features will remain active.
The terminals marked Ta and Se are for external zero-voltage controls including room thermostats, time clocks,
zoned system controls and weather compensating controls. Connection of these controls is covered in Section 7.
