Description
High temperature system setpoint.
If Par 14 = 0 is the high temp. system setpoint
If Par 14 = 1 is the max temp. of the high system
Hot water system setpoint
Low temperature system setpoint.
If Par 22 = 0 is the low temp. system setpoint.
If Par 22 = 1 is the max. temp of the low system
Description
Defines difference between flow and return
temperature. This value remains constant with
changes in power thanks to the primary circulator
modulation
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
Setpoint of power supplied in hot water mode
Max. value hot water setpoint
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
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.
Burner goes out after said differential exceeds hot
water setpoint.
E.g. 50°C + 1°C = 51°C
Burner ignites after said differential sinks below hot
water setpoint.
E.g. 50°C–5°C= 45°C
Max. number of burners functioning in hot water mode
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.)
Heating power setpoint
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.
