DESCRIPTION OF THE PARAMETERS
Parameter 15 (2CA/32783): Gas pressure switch attached
This parameter denes whether or not a gas pressure switch is attached to the boiler.
Parameter 16 (2DA/32784): Water pressure sensor attached
This parameter denes whether or not a water pressure sensor is attached to the boiler.
Parameter 17 (2DB/32785): Water pressure warning
If the water pressure falls below the value set under this parameter, “W:01” appears on the display and the boiler
output reduces to the level set under Parameter 24.
Parameter 18 (2DC/32786): Water pressure hysteresis
The water pressure warning is only lifted, when the water pressure rises to Parameter 17 + Parameter 18.
Parameter 19 (2DD/32787): Blocking pressure min
If water pressure falls below the value set here, the burner switches off. The blocking notication “B:05” is shown on
the display.
Parameter 20 (2DE/32788): Blocking pressure min - hysteresis
Blocking caused by insufcient water pressure is only lifted when the water pressure rises back to Parameter 19 +
Parameter 20.
Parameter 21 (2DF/32789): Blocking pressure max
If water pressure rises above the value set here, the burner switches off. The blocking notication “B:05” is shown on
the display.
Parameter 22 (2DG/32790): Blocking pressure max - hysteresis
Blocking caused by too high water pressure is only lifted when the water pressure falls below Parameter 21 – Pa-
rameter 22.
Parameter 23 (2DH/32791): Lock-out pressure max
If water pressure rises above the value set here, this causes a lock-out. Locking notication “E:16” is shown on the
display.
Parameter 24 (2DI/32792): Max. boiler performance at pressure warning
If a pressure warning (see parameter 17) is triggered during boiler operation, boiler output is reduced to the value set
here.
Parameter 25 (2EC/32793): Ionisation warning
If, during operation, the ionisation ow falls below this level, a warning “W:02” is shown.
