Description
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 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).

The boiler parameters may only be modified by professionally qualified staff proceeding as follows:
a) press the , keys on the boiler’s front panel together for about 3 s until the parameter H90
appears on the display;
b) press the keys to select the parameter for modification;
c) press the and keys to modify the parameter;
d) press the key to exit the programming function.
e) when programming is finished, warning message E183 will blink for 3 seconds approx.
If the warning continues to blink or if other warnings are displayed, press the reset button
When warning message E153 appears, press the reset button a second time.
The following are the parameters generally used:
