Internal Wiring - IDEAL Logic+ Combi 24 Installation And Servicing

26 inteRnAl WiRinG

The Logic + Combi boiler comes pre-fitted with 1.8m of
mains cable. This must be connected to a permanent live
supply and NOT switched by thermostats/programmers.
For installers wishing to change this cable refer to Frame
28. If the supply cord is damaged, it must be replaced
by the manufacturer, service agent or similarly qualified
persons in order to avoid hazard.
The Logic + Combi boiler comes pre-fitted with a link
wire between the room thermostat/Timer connections on
the terminal strip. This creates a permanent call for heat
and must be removed when adding a room thermostat/
programmer.
The terminal block cover carries two spare fuses for the
main PCB.
To add thermostat/programmer:
1. Isolate the mains supply to the boiler.
2. Remove the front panel. Refer to Frame 39.
3. Swing the control box down into the servicing position.
Refer to Frame 45.
4. Route incoming cables through the grommets in
bottom panel (note, grommets are 'blind' and will
require puncturing) and secure using clamps and
screws provided in hardware pack.
5. Pull off rubber terminal block cover.
6. Connect wires to terminal block, as shown below
7. Re-assemble in reverse order.
