Setting The Boiler Parameters - Baxi Power HT 1.850 Gebrauchsanleitung

IT
The boiler parameters may only be modified by professionally qualified staff proceeding as follows:
AT
a) press the , keys on the boiler's front panel together for about 3 s until the parameter H90 appears on
the display;
GB
b) press the keys to select the parameter for modification;
c) press the and
d) press the key to exit the programming function.
The following are the parameters generally used:
Parameter N. Description
H90 Minimum D.H.W. temperature setting (°C).
H91 D.H.W. activation program
(0=active; 1=not active)
H505 Maximum temperature (°C) of the central heating circuit HC1 corresponding to:
-
-
-
H507 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.
H516 Automatic Summer / Winter switching temperature (°C).
H532 Selection of temperature curve of central heating circuit HC1 (see Graph 1)
H533 Selection of temperature curve of central heating circuit HC2 (see Graph 1)
H536 Selection of central heating power (N. of fan rpm)
H612 Speed setting (rpm) : minimum power
H613 Speed setting (rpm) : maximum power
H544 Pump post-circulation time in central heating mode (min)
H545 Burner operating pause time between two start-ups (s)
Hydraulic system setting (see instructions provided with the SIEMENS AGU2.500 accessory)
H552
