3.5 Remote Timers for Combis
3.5.1 Installation of a remote two channel programmer (option 1)
Connecting the programmer in this
manner will bypass the CH and HW on/
off switches on the boiler control panel.
A separate connection to the boiler 3 pin
mains plug is NOT required.
Inside the boiler control panel, remove
the purple and white wires connecting
terminals 5 and 3 on the terminal block
with terminals 9 and 28 on the PCB.
Connect the programmer to the
permanent live mains supply via a fused
isolator as shown.
Connect the boiler to the programmer via a 5 core cable as shown ensuring that the
earth is connected to one of the earth post inside the control panel and that the
permanent live is connected to terminal 2 on the PCB. Failure to connect the
permanent live to the boiler in this way will prevent the mains lamp and pump
overrun thermostats from operating. It will also prevent the built-in frost protection of
a Kabin Pak Combi from operating.
3.5.2 Installation of a remote two channel programmer (option 2)
Connecting the programmer in this
manner will bypass the CH and HW on/
off switches on the boiler control panel.
The boiler and programmer will both
be powered from the boiler 3 pin mains
plug.
Inside the boiler control panel, remove
the purple, white and brown wires
connecting the CH and HW switches to
the 6 pin connector of the terminal block.
Connect the programmer to the 6 pin
connector via a 5 core cable as shown
ensuring the earth is connected to one of
the earth posts inside the control panel.
Connect the boiler 3 pin mains plug to a permanent live mains supply via a fused
isolator. Failure to connect a permanent live to the boiler will prevent the programmer,
boiler mains lamp and pump overrun thermostats from operating. It will also prevent
the built-in frost protection of a Kabin Pak Combi from operating.
