16 INTERNAL WIRING
17 EXTERNAL CONTROLS
External wiring must be in accordance with the current I.E.E.
(BS 7671) Wiring Regulations.
The wiring diagrams illustrated in Frames 19-21 cover the
systems most likely to be fitted to this appliance.
For wiring external controls to the Mexico Super 3 RS boiler
reference should be made to the system wiring diagrams
supplied by the relevant manufacturer, in conjunction with the
flow wiring diagram below and also Frame 18.
Difficulty in wiring should not arise, providing the following
directions are observed:
1.
Controls that switch the system ON and OFF, e.g. a time
switch, MUST be wired, in series, in the live mains lead to
the boiler.
2.
Controls that override an on/off control, e.g. a frost
thermostat, MUST be wired into the mains lead, in parallel,
with the control(s) to be overridden. Refer to Frame 22.
3.
If a proprietary system is used, follow the instructions
supplied by the manufacturer.
Advice on required modifications to the wiring may be obtained
from the component manufacturers.
Note.
If there are no external controls the circulating pump
MUST be wired into the control box.
