If heat is demanded by the DHW and the elements are energized a small red indicator is
displayed to the right of the temperature display.
This light will go out when the desired temperature is reached.
The setting of the DHW temperature can be modified by pushing either the
button or the
button and
using the same buttons to adjust the setting that flashes on the display. The modified setting will be stored
automatically after a few seconds, or instantly by pushing the
button.
The DHW setting can be varied between 20 and 55°C.
The DHW has priority over the central heating operation and so the outputs are never added together.
Water storage at maximum temperature will provide the best protection against the possible formation of
legionella bacteria.
6.4 CENTRAL HEATING OPERATION
First ensure that any external controls such as room thermostat or time clock are demanding heat.
To select the heating function, push the
button.
Pushing again
will switch the function off and return display to just a red dot.
When the heating mode is selected the display will show the
temperature of the heating water.
We can modify the setting of the temperature of the water by pushing either the
button or the
button
and using the same buttons to adjust the value that flashes on the display. The modified setting will be stored after
a few seconds or instantly by pushing the
button.
The heating setting can be varied between 8ºC and 85°C.
The symbol H appears after the 85 value or before the 8 value. If this value is selected, the heating will function in
anti-freeze mode.
If the setting is higher than the actual temperature of the heating
water and external control demands heat, the heating will connect
and a small red indicator of the consumption of heating resistances
will light up.
6.5 ANTI-FREEZE MODE (Frost Protection)
It is possible to select an anti-freeze mode for frost protection during periods of inactivity. The power supply to
the boiler must be maintained.
By attempting to set a central heating temperature below the 8ºC value or above the 85ºC value the symbol H will
appear on the display. By selecting this value, the heating will only work in anti-freeze mode i.e. if the boiler
temperature falls to 7ºC the heating will activate automatically.
6.6 USER PARAMETERS.
The user can change a number of parameters to set some functions of the boiler to the needs of each customer.
To access the user parameters menu – with front display OFF, press and hold the
and
buttons for at
least 5 seconds.
