Description
Minimum D.H.W. temperature setting (°C).
D.H.W. activation program
(0=active; 1=not active)
Maximum temperature (°C) of the central heating circuit HC1 corresponding to:
- the main circuit in systems with just one zone;
- the circuit of the zone where the QAA73 room temperature control device is installed in case
of systems with more than one high-temperature zone;
- the high temperature zone circuit in mixed systems and if the SIEMENS AGU2.500 accessory
is used.
Maximum temperature (°C) of the central heating circuit HC2 of a system with more than one zone,
corresponding to the circuit of the low-temperature zone if the SIEMENS AGU2.500 accessory
is used.
Automatic Summer / Winter switching temperature (°C).
Selection of temperature curve of central heating circuit HC1 (see Graph 1)
Selection of temperature curve of central heating circuit HC2 (see Graph 1)
PWM (%) Setting: Ignition load
Speed setting (rpm) : Ignition load
PWM Setting (%) : minimum power
PWM Setting (%) : maximum power Central heating / Domestic hot water
Speed setting (rpm) : minimum power
Speed setting (rpm) : maximum power Central heating / Domestic hot water
Pump post-circulation time in central heating mode (min)
Burner operating pause time between two start-ups (s)
Hydraulic system setting (see instructions provided with the SIEMENS AGU2.500 accessory)
H552 = 50 with AGU2.500 and with QAA73 + zones with room thermostat
H552 = 80 with RVA 47
Conguration of heating circuits
H553 = 12 with AGU2.500
Programmable function:
Conguration of system with supplementary pump
H632 = 00001111 with AGU2.500 and with QAA73 + zones with room thermostat
H632 = 00001111 with RVA 47
The value of Bit could be 1 or 0.
Press the keys 5 and 6 to select the bit to modify (b0 is the bit on the right, b7 is the last bit on
the left).
To modify the Bit value press on the keys 7 and 8
