2.1 BEFORE SWITCHING ON
Before switching the appliance on, please familiarise yourself
with:
- how to isolate the appliance from the gas, water, and electricity
supplies;
- how to check and top-up – if necessary – the system water
pressure;
- the time clock or programmer (if fi tted);
- any external thermostats and their functions;
- the appliance controls.
2.2 APPLIANCE CONTROLS (see
fi
g. 1)
The appliance controls are situated on the lower front of the
appliance. The appliance controls include:
- pressure gauge;
- appliance mode selector;
- temperature selector
NOTE
The appliance frost protection is active in all the boiler modes.
The temperature selector can be used to vary the temperature
of the water that circulates around your radiators.
The temperature range is adjustable between 40°C and 80°C.
Refer to the main appliance status table for fault indicator and
boiler status.
2.3 LIGHTING THE BOILER
Ensure the gas and electrical supply to the boiler are
turned on.
Turn the mode selector switch to the
ON
position. When there
is a request for heating or hot water via the time clock or pro-
grammer, the boiler will begin an ignition sequence. When the
appliance reaches the CH set temperature, the burner will go
off for a minimum period of approximately 3 minutes.
When the programmer/time clock or external thermostats
heating request has been satisfi ed, the appliance will switch
off automatically.
2.4 ADJUSTING THE HEATING TEMPERATURE
Rotate the temperature selector – clockwise to increase, counter-
clockwise to decrease – to the desired temperature setting. The
temperature can be set from a minimum of 40°C to a maximum
of 80°C (if standard CH mode is selected).
2.5 EXPLANATION OF FEATURES
Although the Vokèra Mynute
i
has been designed for simplicity
of use, it utilises the latest in boiler technology, enabling a host
of functions to be carried out simultaneously.
2.6 AUTOMATIC TEMPERATURE CONTROL
The automatic temperature control function (SARA), permits the
boiler (when the heating temperature selector is set within the
blank bullet points) to automatically adjust (raise) the heating.
The activation and the disable of the function is visualized on
the display.
