temperature of 18oCis attained. In the event that the water

temperature falls below 3oC, the diverter valve switches to Domestic

Hot Water and the burner fires on minimum power until a

temperature of 33oCis attained.

This device is only activated when the boiler is operating perfectly

and

-the system pressure is sufficient;

- the boiler is powered electrically;

- gas is available.

Schedule an annual maintenance check-up for the boiler with a

CORGI registered Service Engineeer in the UK and with a competent

person as described in I.S.813 for IE.

cold water inlet connection and the C.H. flow

connection;

- Open the black lever on the valve for the C.H. return

connection and slowly open the black handle on the

valve for the cold water inlet until water is heard

passing through the valves;

- Once the pressure gauge 33 (Fig. 6.1) reads between

1and 1.5 bar close the levers on both the cold water

connection and the C.H. return connection

- Switch the power to the boiler back on.

NOTE:THE FLEXIBLE HOSE MUST BE REMOVED ONCE THE

SYSTEM HAS BEEN FILLED.

clockwise until the correct time is lined up with the arrow C(Fig. 8.1).

3. To Set the "On" and "Off" times

The clock uses a 24hours system. e.g. 8 = 8.00 am and

18 = 6.00 pm "ON" periods are set by sliding all tappets between the

"ON" time and the "OFF" time to the outer edge of the dial.The tappets

remaining at the centre of the dial are the "OFF" periods.

Operating the time switch

The steps marked with the symbol “ ” are necessary to carry out a

switching program.

Preparing for Operation

Activate the “Res” switch (=RESET) to reset the time switch to its

default setting (activate using a pencil or similar pointed instrument).

Do this:

-every time you wish to “reset” the time switch

-to erase all switching times and the current time of day.

After approximately two seconds the following display appears:

Enter current time and weekday

-Keep the “ ” key pressed down

During the summer time period press the +/- 1h key once.

Enter the hour using the “h” key

Enter the minutes using the “m” key

Enter the day using the “Day” key

1=“Monday”..............7 = Sunday

-Release the “ ” key.

Entering the switching times

You have 20 memory Iocations available. Each switching time takes

up one memory location.

Keep pressing the “Prog” key until a free memory location is shown in

the display “– –:– –”.

8.2 Setting the Digital Clock

Programme ON or OFF with the “ ” key:

“ ”= OFF; “ ”= ON

Enter the hour using “h”

Enter the minutes using “m”

If a switching command is to be carried out every day (1 2 3 4 5 6

7) then store using the “ ” key, otherwise select the day(s) it is to

becarried out by using the “Day” key.

When the day seIection is left bIank, the programmed switching

instruction operates at the same time every day

123456 = Monday – Saturday

12345 = Monday – Friday

67 =Saturday – Sunday

Selection of single days: 1 = Mon. .............. 2 =Tues.

Save the switching time with the “ ” key.

The time switch enters the automatic operating mode and displays

the current time of day.

Begin any further entry of a switching time with the “Prog” switch. If

your entry is incomplete, the segments not yet selected will blink in

the display. After programming is completed, and you return the

time clock to the current time display with the “ ” key, the time

clock will not activate any switching instruction required for the

current time. You may need to manually select the desired

switching state with the “ ” key. Thereafter, as the unit

encounters further switching instructions in the memory in real time,

it will correctly activate all subsequent switching instructions.

Manual Override Switch “ ”

With the “ ” you can change the current setting at any time. The

switching program already entered is not altered.

Reading the programmed switching times

Pressing the “Prog” key displays the programmed switching times until

the first free memory location appears in the display “– – : – –”.

If you now press the “Prog” key once again, the number of free memory

Iocations will be displayed, e.g. “18”. If all memory locations are

occupied, the display “00”appears.

Changing the programmed switching times

Press the “Prog” key repeatedly until the switching time you want to

change is displayed. You can now enter the new data. See point

“Entering the switching times”.

Notes on storing switching times:

If you end your entry of the switching times by pressing the “Prog” key,

then the switching time you have entered will be stored and the next

memory location displayed.

In addition, a complete switching command is stored automatically

after around 90 seconds provided no other key is pressed. The time

switch then enters the automatic operating mode and displays the

current time again.

Deleting individual switching times

Press the “Prog” key repeatedly until the switching time you wish to

delete is shown in the display. Then set to “– –” using the “h” or “m” key

and keep the “ ”key pressed down for around 3 seconds. The

switching time is now erased and the current time is displayed.

AM / PM time display

If you press the “+/-1h” and “h” keys at the same time, the time display

switches into the AM/PM mode.
