Desired Room Temperature
The desired room temperature can be set
from 5 to 30 °C, in 0.5 increments.
The World Health Organisation
recommends a room temperature of 18–24
°C for healthy living.
NB: If Day or Night Mode are active, the
temperature cannot be adjusted, the Plus
and Minus buttons will be greyed out.
1. The current desired room temperature is
displayed.
2. Adjust by pressing Plus or Minus button.
Domestic Hot Water
The Alde boiler stores 8.4 Litres of hot water
as standard. If the hot water cylinder is
empty, the air is heated but no damage can
result.
In a good summer, for example, lower
the desired temperature on the control panel
to around 10 °C. The central heating will not
circulate (unless the temperature drops to 10
°C), but you can still control hot water.
NB: If Day or Night Mode Sans Hot Water
are active, the hot water cannot be
adjusted, the Plus and Minus buttons will
be greyed out.
1. Hot Water Ignore. Volume bar empty. No
attempt is made to heat hot water
specifically. This saves energy when the
freshwater is drained down.
2. Hot Water Normal. Volume bar half-full.
Hot water is heated to greater than 50 °C.
NB: If Circulation Pump is set to
Continuous, this option will not be
available.
3. Hot Water Boost. Volume bar full. Central
heating circulation is disabled for 30 mins.
Hot water is heated to greater than 65 °C.
After 30 mins the system reverts to Hot
Water Normal.
4. Adjust by pressing Plus or Minus button.
Electric Heating
Check that 230 V 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 3 kW.
1. Select Off, 1, 2 or 3 kW electric heating.
More power equals better performance,
but may be restricted by the current
(amps) limit on the electric hook-up.
2. Adjust by pressing Plus or Minus button.
Max current draw from 230 V supply is 4.5 A
on 1 kW, 9 A on 2 kW, 14 A on 3 kW. 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.
1. Press the Flame button to select gas
heating. Green is on, blue is off.
Use both gas and electric heating for best
performance.
