Failure to connect thepermanent live to the boiler in this way will prevent the mains lamp and pumpoverrun thermostats from operating. It will also prevent the built-in frost protection ofa Kabin Pak Combi from operating.3.5.2 Installation of a remote two channel programmer (option 2)Connecting the programmer in thismanner will bypass the CH and HW on/off switches on the boiler control panel.The boiler and programmer will bothbe powered from the boiler 3 pin mainsplug.Inside the boiler control panel, removethe purple, white and brown wiresconnecting the CH and HW switches tothe 6 pin connector of the terminal block.Connect the programmer to the 6 pinconnector via a 5 core cable as shownensuring the earth is connected to one ofthe earth posts inside the control panel.Connect the boiler 3 pin mains plug to a permanent live mains supply via a fusedisolator. Failure to connect a permanent live to the boiler will prevent the programmer,boiler mains lamp and pump overrun thermostats from operating.
