Ideal Logic System - Installation and Servicing
25 INTERNAL WIRING
The Logic System 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 31.
Connecting the Switched Live to the Boiler
1. Consult the Y Plan and S Plan diagrams below.
2. Isolate the mains supply to the boiler
3. Remove the front panel. Refer to Frame 7.
4. Swing the control box down into the servicing position.
5. Route incoming cable through a grommet in the bottom panel (note that
the grommets are “blind” and will require puncturing) and secure using the
clamp and screws provided in the hardware pack.
6. Connect the switched live to the terminal block as shown.
FROST THERMOSTAT - WIRING
If parts of the system are vulnerable to freezing or the programmer is likely to be left off
during cold weather, a frost stat should be tted in conjunction with a pipe thermostat.
