Ideal Logic Combi -
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.
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.
To add thermostat/programmer:
1.
Isolate the mains supply to the boiler.
2.
Remove the front panel. Refer to Frame 37.
3.
Swing the control box down into the servicing position.
Refer to Frame 30.
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.
Connect wires to terminal block, see instructions below.
6.
Swing the control box back up into the operating
condition and re-fit the front panel ensuring a good seal
is made.
