Equithermal mode – curve slope
Press the button – letter E with
the characters (-) and (1) through to (9)
attached will appear on the display. By
pressing the buttons, select the re-
quired equithermal curve. The curve’s slope
grows with the growing number (E1 < E9)
– see Fig. 2.
If you wish to turn the equithermal control
off, select (E-).
By pressing the button, the selecti-
on is saved in the memory and the system
switches to the next mode
Note:
Equithermal control requires an
external sensor to be connected to the
boiler, which must not be set to the SUM-
MER mode. If your boiler does not have an
external sensor, the error message code
F5 will appear on the display!
Equithermal mode – paralel curve
shift
Press the button – letter P with
the characters (-) and (1) through to (9)
attached will appear on the display. By
pressing the buttons, select the re-
quired shift as described below, or switch
the mode off by selecting (P-).
Values with a minus sign are subtracted
and values with a plus sign added to the
heating water temperature (determined
by the equithermal curve as a function
of the outdoor temperature). By pressing
the button save the setting in the
memory and return back to the starting
position.

Equithermal curves
Example:
• You have selected the E6 curve slope
and the outdoor temperature is -10 °C.
The corresponding heating water tempe-
rature is 73 °C.
• You have selected parallel shift P3... -6
°C, the resultant heating water temperatu-
re will be 73 - 6 = 67 °C.
