INTERNAL WIRING
The Logic Combi ES boiler comes pre-tted 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 35. If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualied persons in order
to avoid a hazard.
The Logic Combi ES boiler comes pre-tted 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 44.
3. Swing the control box down into the servicing position. Refer to Frame
50.
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 opposite.
6. Swing the control box back up into the operating condition and re-t
the front panel ensuring a good seal is made.
