• 1: Temperature sensor connected at the
appliance

• 3: Low-loss header without temperature sensor
This setting defines, where the temperature
sensor for the low-loss header is connected.

%
▶ Set thermal output in percent.
▶ Measure gas flow rate.
▶ Compare measured result with the setting
tables (
page 69). Correct the setting in the
case of any deviation.
3-b2 Standby time
• 3 ...
5
... 60 minutes
The time interval determines the minimum dela
between starting and restarting the boiler.
If an outside temperature-controlled heating
controller is connected, this setting is optimised
by the heating controller.
3-b3 Temperature interval for switching off
the burner and switching it on again
• -15 ...
-6
... -2 K ( °C)
Difference between current flow temperature and
set flow temperature up to the point when the
burner is switched on.
If an outside temperature-controlled heating
controller is connected, this setting is optimised
by the heating controller.
3-C4 Turbine signal delay
•
2
... 16 x 0.25 seconds
The delay prevents sudden changes in the water
supply pressure from causing the burner to briefly
operate although no water is drawn off
3-C5 DHW start delay
•
0
(not active) ... 50 seconds
The delay concerns heating operation in systems
in which the DHW outlet of the solar-heated DHW
cylinder is connected to the cold water inlet of a
combi boiler. DHW heating by the combi boiler will
be suppressed expecting that solar thermal DHW
will reach the hot water temperature sensor prior
eliminating the need to run the boiler. This avoids
unnecessary operation of the combi boiler. Set the
heating delay in accordance with system
conditions.
3-C6 Preheat
• 0 ...

... 30 minutes
The heating mode is disabled for this period of
time following DHW heating.
3-C8 Thermal disinfection
•
OFF
• ON
When Thermal Disinfection is activated: Water will
be heated up to 70 °C for the duration of 10
minutes, when domestic hot water is extracted.
Thermal Disinfection will be completed after 10
minutes or after a domestic hot water extraction of
3 minutes.
