VOKERA Compact A User manual

Your Vokèra Compact A combi boiler
How to use your Vokèra Compact A
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 ad usted using the hot
water 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 37°C to a maximum of 60°C.
The central heating (radiator) temperature can easily be ad usted 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.
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.

Setting the Vokèra Mechanical Clock
If your boiler has been installed with the Vokèra mechanical clock, it can be
adjusted as follows:
The time of day can be set by grasping the outer edge of the black dial and
turning it in a clockwise direction until the correct time is in line with the pointer.
Setting the “switching times”
The “ON” periods are set by sliding the white tappets, adjacent to the time
periods required, to the outer edge of the dial. The tappets that remain at the
centre of the dial will be the “OFF” periods.
Note: each white tappet is equivalent to 1 minutes and this is the shortest
switching time for ON or OFF periods.
- To select “AUTO” mode move the selector switch in central position.
- To select “ON” mode move the selector switch in the bottom position.
- To select “OFF” mode move the selector switch in the upper position.
