Installation instructions
MAKE SURE MAINS INPUT HAS
A
3 AMP
FUSE FITTED.
Installation should be carried
out by a qualified electrician or
heating engineer.
Position the wallplate with
70 mm clearance to its right,
25 mm above and 150 mm below.
Ensure that the supporting
surface will fully cover the back
of the timeswitch.
Fix the wallplate, terminals at
the top, either direct to a flat
wall using wall plugs and 1" x
No.6 woodscrews or on a flush
mounting single conduit box
type UA1 (BS4662) using M3.5 x
14 mm screws. DO NOT use a
surface mounting box.
Make wiring connections as
Tempus 7 electronic programmer
User instructions
shown in the wiring diagram. For
surface wiring, snap out the
cable entry strip on the bottom
edge of the wallplate. Tempus 7
is double insulated and needs
no earth connection but an
earth continuity terminal is
provided if required.
Select 5/2 day or 7 day mode
and pumped or gravity
operation by referring to the
jumper positions diagram.
There are two jumpers
marked A/B and C/D. Jumpers
should be removed if necessary
and placed across the pins which
correspond to the desired option.
Fit the Tempus 7 onto the
wallplate and tighten the
securing screws. Check that the
fuse is rated correctly (3A) and
switch on the mains supply.
Never fit the
programmer to a live
wallplate

The Tempus 7 electronic
programmer will automatically
switch ON and OFF up to three
times a day. You can select one
set of times for weekdays and
different times for weekends
(5/2 day), or programme
different times for each day of
the week (7 day). Hot water and
heating times can be set
independently.
The BOOST feature gives an
extra one or two hours ON time
when selected. The display will
show the next switching time as
well as the actual time of day. In
the event of a power failure, the
battery back-up will hold the
programme times in memory.
All changes to clock and
programme times are made
using the slider switch, together
with the TIME and DAY buttons.
Follow the step-by-step
instructions overleaf to set your
desired programme.
Please read the following
notes before programming
your Tempus
You cannot set the first ON
before midnight (i.e. the
previous day).
If you try to set an ON time
after
it's matching OFF time,
both will ‘lock’ and the ON and
OFF symbols in the display will
flash alternately.
To omit one day from your
programme whilst in 7 day
mode, set each pair of ON and
OFF times together. Times must
be different for each pair to
avoid disrupting the logic of the
Tempus.
Press SELECT and TIME
+
at
the same time to return all
settings to factory pre-sets.
The slider switch must be in
the RUN position before the
cover will close.
To select 5/2 day or 7 day
modes see installation
instructions on back page.
