SINGLE CHANNEL PROGRAMMER.
_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
This programmer will switch your central heating or hot water at your chosen times. You simply enter the 'on' and
'off' times you require and run the programmer.
Key to abbreviations:

1: Precautions Against Electric Shock Hazard:

Detaching your programmer from the wall exposes electrically live terminals in the same way as removing the cover
from a mains wall socket exposes live terminals. The programmer is detached from the wall by unlatching the clip
underneath the flap. This should only be performed by suitably qualified personnel and with the power switched off.
Ensure that your programmer has been installed by a qualified professional. Installation by non professionals could result in
serious injury. As an added precaution ensure your programmer has been mounted in a location out of the reach of children

blinking. Press the DAY button until the day pointer points to the correct day. Use the + and – buttons to set the
correct time. Press the NEXT button. The date will blink. Set using the + and – buttons. Press NEXT again. The
month will blink. Set by using the + and – buttons again. Press NEXT and use the + and – buttons to set the first

3: Entering on/off Times:

3.1: Entering on/off times:
Move the set switch to SET PROG. "CH ON 1" will blink indicating that your system is set to come 'on' as
displayed. Use the + and – buttons to set the time you require.
Press NEXT: the display shows "CH OFF 1" and the switch 'off' time. Adjust if required.
Press NEXT again to set the 'on' time for your second heating period, (CH ON 2).
Press NEXT again to set CH OFF 2.
Press NEXT again: depending on your programmer set up "CH ON 1" or "CH ON 3" will be displayed.
If "CH ON 1" is displayed, your programmer has been set-up to give two "ON" periods per day. You have already
set the times for both these periods and can now go to paragraph 3.2. (see notes 1).
If "CH ON 3" is displayed, your programmer has been set-up to give three "ON" periods per day. Enter the times
for the third period in the same way as for the previous period and proceed to paragraph 3.2. (see notes 1).
3.2: On/off Times for the Rest of the Week:
Depending on how your programmer has been set-up, (see note 1), the day pointer, (on the display), will be in
one of three formats:
a) Pointer appears at all seven days. The times entered in step 3.1 apply to all seven days. In this set up you do
not have the option to change individual days. (see note 1).
b) The pointer appears at one day only: The times entered in step 3.1 apply to one day only. Press the COPY
button. The pointer moves to the next day, copying the settings from the first day. If required, modify the settings
using the +, -, and NEXT buttons. Repeat the process for the remaining days.
c) The pointer appears at either the five week days or the two weekend days. The times entered in step 3.1 apply
to either the weekdays or to the weekend days. Press COPY. The pointer moves to the other group of days
copying the times in the process. Modify if required using the + and - buttons.
