ELECTRIC HEATING
Check that 230v supply is displayed on the
Standby Screen. The Alde boiler is programmed
to use power economically and there are times
when it may use no power at all, even if set to
3kW.
• Select Off, 1, 2 or 3kW electric heating.
More power equals better performance,
but may be restricted by the current
(amps) limit on the electric hook-up.
• Adjust by pressing plus or minus button.
Max current draw from 230v supply is 4.5A
on 1kW, 9A on 2kW, 14A on 3kW. If the electric
supply has unstable voltage, the amperage will
also fluctuate.
GAS HEATING
The Alde boiler is programmed to use power
economically. The gas burner has two stages,
shifting dynamically between low or full flame.
There are times when it may use no power at
all, even if gas heating is selected.
• Press the Flame button to select gas
heating. Green is on, blue is off.
Use both gas and electric heating for best
performance.
