The Vokera 2 channel 7 day programmer will automati-
cally switch your central heating system ON and OFF
once, twice or three times a day, whichever you wish and
at whatever times you choose each day of the week.
It incorporates a rechargable battery back-up system to
protect the programme during power cuts of up to 24
hours, even though display will go blank.
The clock in the programmer has to be set to the actual
day of the week and time of day.
It must then be told at what times you want it to switch your
Central Heating (CH) and Hot Water (HW) system ON
and OFF for each day of the week. This set of switching
times is known as a programme.
The programmer has an in-built programme of standard
switching times. They may well be right for you, but if they
are not exactly what you want you can change them.
The standard programme is shown in the table on the
following page, and, for simplicity, the switching opera-
tions are described as ON1, OFF1, ON2, OFF2, ON3,
OFF3 from now on.
SETTING THE CLOCK
Use the chart to plan your own programme before
proceeding.
Switch on the mains supply to the boiler, then switch the
mode selector switch (1) ON. Press and release the
button marked SET.
The display will show
Press and release the button marked YES to answer the
question and the day part of the display will flash. Use +
and - buttons to change to the correct day then press SET
again.
This will cause the hour part of the display to flash. Use
the + and - buttons to change to the correct hour (check
AM or PM) then press SET again. This will cause the
minutes part of the display to flash. Again use the + and
- buttons to change the minutes as required, then press
SET again.
The display will now show
(see later instructions for changing your programme).
Press the SET again
The display will now show
(again see later instructions)
Press the SET button again.
The display will show
(again see later instructions about this holiday setting
feature). Press SET once again and the display will show
actual time of day and day of the week you have set.
PROGRAMME TEST
As described earlier, there is a place in the programming
sequence where you will be given the opportunity to
press YES when the display shows TEST ? This feature
is available so you can quickly run through the ON and
OFF times set to make sure they are what you want.
Answer YES and the display will show a time just past
midnight on the morning of the day of the week you are
actually in. Now press and hold down the YES button
again. The time display will start to “run” and will pause
for 2-3 seconds when it reaches the ON1 time for that day,
the ON indicator light will be energised as will the circuit
being controlled. If you release the YES button the
display will stop running and give you more than 2-3
seconds to think about a switching time.
Continue pressing YES and the display will now “run” to
the OFF1 time when it will pause again and the time
switch will switch off. It will then “run” to the ON and OFF
times in turn, pausing at each before moving to the next
day and identifying the ON and OFF times in the same
way.
The programmer will continue identifying the ON and
OFF times in this way for each day in sequence until you
press the SET button when it changes to the holiday
setting mode. Pressing SET button again returns the
module to normal operating mode.
HOLIDAY SETTING
NOTE: This useful feature allows you to set the number
of days you want your system to be permanently off
before automatically switching on at the programmed
time.
The programmer counts each pass through mid-night as
one day, so if on Saturday morning you don’t want the
system on again until Tuesday morning you set the
counter to 3. If when the display shows SET H’DAY ? you
press the YES button the display will show OO. By using
the + and - buttons you can now set the number of days
you want the system to be off, a maximum of 99 days is
possible.
Now press SET again and the display will be blank apart
from H’DAY. Having counted down to zero, the
programmer will switch the system on at the times set for
that day. If you wish to cancel the H’DAY setting, press
any button and normal operation will be resumed. Your
module is now in the operating mode and ready to work
using the built-in standard programme times.
PROGRAMME OPTIONS
Hot water and central heating can be operated
independantly.
The programmer gives you 4 options for both CH and
HW:
OFF - Off all the time
TIMED - On/Off at all periods set in programme
ONCE - On for one period each day (ON1 >> OFF3)
ON - On all the time
