FACTORY PRESET TIMES
NOTE: The 2nd "ON" and "OFF" preset time will not bring the
boiler on. In most cases this may not be required but can be
programmed by the user if desired.
The programmer has an "advance" feature to manually switch
the boiler "ON" or "OFF" and a holiday feature so that you can
programme the boiler to start automatically when returning from
holiday. Details on how to set these feature are given further on
in these instructions.
Setting the Time
Make sure there is an electrical supply to the boiler and the
boiler is switched "ON".
Place the slide switch to
Press the "RESET" (res) button for a few seconds, using a
pointed object such as a pencil. When released the display will
begin to flash, see diagram 2. Using the + and - buttons, set
the display to the correct time in twenty four hour format, for
example, 1300 for 1pm, see diagram 3.
Helpful hint The + and - buttons are used to change the times.
Press and release for small changes, hold the button down and
the time will change quickly.
To use the internal, factory set, programmes place the slide
switch to the 'RUN' position. The display will show the current
time and the "ON" or "OFF" symbol will be displayed according
to whether the programmer has switched the boiler on or off.
To Override or Advance the programmer
To advance the time clock operation, that is, switch the heating
on when it is off or vice versa, press the "ON/OFF" button. The
programmer will switch the heating on or off and the "ON" or
"OFF" symbol will flash on the display to show that it has been
overridden, see diagram 4
.
Note: The boiler will stay "ON" or "OFF", as selected, until the
programmer reaches its next on or off time. From then on, the
programmer will switch the boiler on and off according to the
internal programme.
When the boiler is again controlled by the internal programme
the "ON" or "OFF" symbol will stop flashing. The operation of
the programmer can be overridden in this way at any time.
