Setting The User Parameters - ATTACK DPX15 Instructions For Use Manual

3.5 SETTING THE USER PARAMETERS

The menu for displaying and setting the user parameters is accessible after short pressing of the
OK button. The „+" and „–" buttons are used to browse in settings and parameters. The
appropriate parameter selected becomes adjustable by the „OK" button and starts to flicker.
Then it can be changed by the „+" and „–" button and confirmed by „OK". Some of the
parameters are only informative and they cannot be changed. To exit the menu, confirm the
[End] by „OK" button. After remaining more than 1 minute without the user´s intervention, the
controller switches the display to the basic mode.
Table 2. User parameters:
Indication Parameter
C 45 Adjusted boiler temperature
Operating mode of the circuit pump ('C' –
co C
WINTER, '–' – SUMMER)
Operation of the D.H.W. pump ('u' – casual
cu u
mode, 'd' – elimination of legionella bacteria)
Current temperature measured in the
u50°
accumulation tank or D.H.W. tank
150° Current flue gas temperature
End Exit from user parameters
[C 45] – Adjusted boiler temperature – this is the value of boiler water temperature the
regulator is going to reach while in the WORK mode. It is set by turning the thermostat knob
manually (8) and shown briefly on the display (6).
[co C] – WINTER/SUMMER mode – the winter mode is indicated by the 'C' letter. Then is the
circuit pump controlled by the room thermostat and distributes the heat into the heating
system. The summer mode is indicated by the „–" sign. Then is the circuit pump out of order and
the heat generated by boiler is only used to heat the D.H.W. tank. If there is not D.H.W. tank in
the system (additional sensor is not connected), it is not possible to select the SUMMER / WINTER
mode.
[cu u] – Mode of D.H.W. tank warming – the regulator enables the casual D.H.W. tank warming
„u" or the mode to eliminate the legionella bacteria „d". After the „d" mode is selected, the
temperature of 75 °C is achieved in the D.H.W. tank. When this temperature is achieved, the
controller switches into the mode of the casual D.H.W. tank warming „u". The option of
elimination the legionella bacteria is not available, if the additional outlet and sensor are not set
for the D.H.W. warming.
CAUTION! Not to get hurt by the hot water, it is recommended to set this mode, when
the D.H.W. is not being used (e.g. during the night).
[u50°] Temperature of additional sensor – this is the value of current temperature of the
D.H.W. tank or of the accumulation tank of the heating system. This temperature is not displayed
in the user menu, if the additional output is not used.
[150°] Flue gas temperature – this value represents the current temperature of flue gas, if the
parameter for flue gas temperature is set in the service parameters.
