Description
Defines the type of hydraulics in the boiler (0 = instant; 1 =
storage tank).
Defines the maximum operating speed of the circulator (If
A1 = A2 circulator operating at set speed).
Defines the minimum operating speed of the circulator.
Sets the pump operating mode
- DELTA T = 0: proportional head (see par. 1.29).
- DELTA T = 5 - 25 K: ∆T constant (see Par. 1.29).
Establishes the temperature to be added to the DHW
set-point to calculate the flow set to heat the storage tank (if
paired with a storage tank unit)
Temperature value to be subtracted from the DHW set-point
to calculate the boiler ignition to heat the storage tank (when
paired with a storage tank unit)
Establishes the switch-off method in DHW mode.
0 Fixed: the switch-off temperature is fixed at the maximum
value regardless of the value set on the control panel.
1 Correlated: the boiler switches off according to the
temperature set.
