1. Boiler work temperature
The boiler set temperature [C 40] – is the temperature which the controller will try
to achieve in WORK mode.
It is set by direct turning of the knob and is indicated by a short display.
2. Central heating pump work [co C] – WINTER/SUMMER mode –
character “C” indicates that the central heating pump is working. In summer time
the heating can be turned off by choosing the value “-“ with the (-) button which
means turning off the central heating pump.
3. Total bacteria control in the hot water tank – heating up - the
controller allows to manually launch the total bacteria control process in the boiler.
Choosing the “d” value with (+) button starts the process in which the boiler is
trying to achieve the temperature of 75˚C in the hot water tank. In order to start the
total bacteria control process the boiler should be in WORK mode (this mode can
be turned on by START button). E.g. [70˚d] will appear on the display. After
reaching 75˚C in the hot water tank the controller will return to its state before
choosing this option.
CAUTION: the total bacteria control function can switched on at night when the water from the
hot water tank is not used to prevent the users from burn injury.
4. Water temperature readout in hot water tank [u50˚] – this parameter
shows the measured temperature value in the hot water tank.
5. Exit from user mode – choosing the [End] on the display and
pressing OK button causes exit from the parameter setting. Exit from this mode will
also occur if no button is pressed for 1 minute.
