Description
6 Hot water mode 0 0 6
Hot water system configuration:
0 = hot water off
1 = rapid exchanger with probe (instantaneous hot
water)
2 = water tank with probe (hot water produced with
accumulation)
5 = rapid exchanger with flowmeter
6 = water tank with thermostat
7 h.w. max. poten. 230 1 255 Setpoint of power supplied in hot water mode
8 h.w. max T. 60°C 10°C 80°C Max. value hot water setpoint
9 h.w. Priority 0 0 2
Hot water system priority.
0-1 = Hot water functioning with heating until reaching
the heating setpoint. Heating goes off after reaching
the setpoint and hot water continues to work.
2 = Hot water priority
10 T plus water tank 30°C 0°C 50°C
Determines the delivery temperature for domestic hot
water production.
E.g. DHW set point 50°C+30°C. The primary circuit will
be at 80°C.
11 h.w. on diff. 1°C 0°C 20°C
Burner goes out after said differential exceeds hot
water setpoint.
E.g. 50°C + 1°C = 51°C
12 h.w. off diff. 5°C 0°C 20°C
Burner ignites after said differential sinks below hot
water setpoint.
E.g. 50°C–5°C= 45°C
13 Max h.w. Burner 60 0 60 Max. number of burners functioning in hot water mode
14 CH1 adjustment 1 0 3
High temp. heating system configuration
0 = Temperature at fixed point.
1 = Weather with probe outside
2 = 0–10V: power (Acts on power)
3 = 0–10V: temperature (Acts on Temp.)
15 Max. fan speed. 230 1 255 Heating power setpoint
16 Heating priority. 0 0 2
0 = No functional priority
1 = High temp. system priority
The burner always works on high heating if the H.T.
contact is not open.
2 = Low temp. system priority. The burner always
works on low heating, if the H.T. contact is not open.
