Your Vokèra Vision combi boiler

How to use your Vokèra Vision

Your boiler is a combi boiler, it therefore provides hot water whenever a
hot tap is opened, and central heating when required.

Setting the heating and hot water

1. Check

that the boiler is turned on at the electricity supply. If it is not,
turn the boiler ON. It will go through a self-test cycle that will last about
2 ½ minutes. Wait for this to end before adjusting the boiler.

2. Choose with the selector knob:

Standby - no heating or hot water but boiler will protect itself against

frost if cold

Summer position - no heating, just hot water

Winter position - heating and hot water

3. The temperature of the domestic hot water can easily be adjusted using the hot
water temperature selector.

Rotate the temperature selector clockwise to increase the temperature and counter­clockwise to decrease the temperature - until you reach your desired setting. The
temperature can be set from a minimum of 37°C to a maximum of 60°C.

4. Boiler pressure. When the needle is between 1 and 2 on the pressure gauge the

boiler pressure is adequate, if the needle falls below 1 the boiler will need to be
topped up using the filling loop.

can use the button to switch between the three options:

Auto - the heating will be ON only during timed periods selected on the outer clock dial.
Man on - the heating will be on 24 hours a day.
Man off - there is no heating.

Setting the times for heating

The heating ON times can be selected in half hour segments on the outer dial of the clock. An ON
period is shown by an indicator block against the hour or half hour and an OFF period has no block on
the dial.

- Press and hold the button until the display shows ‘PRO.’ The display will change to show the time

as 00:00. A block will flash by the first number on the outer dial and a line will appear beneath day 1.
You can now set the times for heating on Monday beginning at midnight.

- If you’d like the heating be to ON at that time, press the button and if you’d like the heating to

be OFF, press the button.

Note - each press of the or button sets ON or OFF periods then moves to the next half hour segment and the
whole day is set in this way.

- Monday is now set. Once you have finished, press and the line will flash beneath day 2. If you want
to repeat the same heating pattern for Tuesday, press and hold down button until the display
changes.

- Repeat for each day of the week. When day 7 is complete, one last press of button will finish
setting the times and revert back to the normal clock display.

The central heating (radiator) temperature can easily be adjusted using the heating
temperature selector.

Rotate the temperature selector clockwise to increase the temperature and counter
clockwise to decrease the temperature - until you reach your desired setting. The
temperature can be set from a minimum of 40°C to a maximum of 80°C.
