6.5 Remote Timers for Combis
6.5.1 Installation of a remote two channel programmer (option 1)
Permanent Live Supply
The boiler must be supplied with a
permanent live mains supply via a
fused isolator connected to the
boiler 3 pin mains plug into the
control panel.
Failure to connect a permanent live
to the boiler will prevent the
programmer, boiler mains lamp and
pump overrun thermostat from
operating. It will also disable the
built-in frost protection of a Kabin
Pak Combi.
Connecting the Programmer
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.
On Kabin Pak models, ensure the frost thermostat connections to pins 3 and 6 are
left in place.
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, so only one mains connection is
required.
The neutral connection to the 3-pin plug on the control panel must be the
sole mains neutral connection to the appliance.
