NOTES:
a. Wiring diagrams show connections necessary to
a twin switched live output programmer, i.e. one
with separate control of heating and hot water.
b. If simple, single switched, live timeclock is used,
connect switched live supply to both room ther-
mostat and cylinder thermostat, e.g. connect
switched live to either terminal 4 or 6 at junction
box, then link 4 and 6 with a bridge wire.
c. If using boiler with integral programmer, refer to
boiler manufacturers instructions on wiring.
GENERAL
N.B. if using 6” wire, V4043H in S-Plan White wire is not
needed and must be made electrically safe.
