A0 Hydraulic model Denes the type of hydraulics in the boiler (0 = instant; 1 = storage tank) 0 ÷ 1 0
A1
Maximum pump
speed
Denes the maximum operating speed of the circulator
(If A1 = A2 circulator operating at set speed)
A2 - 9 9
A2
Minimum pump
speed
Denes the minimum operating speed of the circulator 1 - A1 6
A3
Pump operating
mode
Sets the pump operating mode
- DELTA T = 0: proportional head (see Parag. 1.28)
- DELTA T = 5 ÷ 25 K: ∆T constant (see Parag. 1.28)
0 ÷ 25 15
A4
Storage tank ow
oset
Establishes the temperature to be added to the DHW set-point to calculate
the ow set to heat the storage tank (only useful with a coupled storage tank
and parameter A0=1).
5 ÷ 50 °C 25
A5
Storage tank
activation oset
Temperature value to be subtracted from the DHW set-point to calculate the
boiler ignition to heat the storage tank (only useful with a coupled storage
tank and parameter A0=1).
0 ÷ 15 °C 3
A6 DHW thermostat
Establishes the switch-o method in DHW mode.
0 Fixed: the switch-o temperature is xed at the maximum value regardless
of the value set on the control panel.
1 Correlated: the boiler switches o according to the temperature set.
0 ÷ 1 0
