The factory settings are depicted as highlighted in the following table.
Settings/adjustment range
• 50 ... 100 % (depending on the appliance output) ▶ Set the heating capacity in percent.
• 3 ... 10 ... 60 minutes
• -15 ... -6 ... -2 K ( °C)
• 2 ... 16 × 0.25 seconds
• 0 (not active) ... 50 seconds
• 0 ... 1 ... 30 minutes
• OFF
• ON
• 0: comfort mode, the device is continually kept at
the set temperature.
• 1: ECO mode, only heat-up to the selected
temperature when hot water is being drawn.
• 3: intelligent
• 0: Pump output proportional to the heat output
• 1: constant pressure 150 mbar
• 2: constant pressure 200 mbar
• 3: constant pressure 250 mbar
• 4: constant pressure 300 mbar
• 5: constant pressure 350 mbar
• 6: constant pressure 400 mbar
• OFF
• ON
• 10 ... 100 %
• 10 ... 100 %
• 1 ... 2 ... 60 minutes
• 24 hours
Remark/restriction
▶ Measure the gas rate.
▶ Compare the measurement with the setting
tables ( page 59). Correct the setting in
the case of any deviation.
The time interval determines the minimum
waiting time between switching off the burner
and switching it back on (standby period).
The difference between the current flow
temperature and the set flow temperature until
the burner is switched on.
The delay prevents sudden changes in the water
supply pressure from causing the burner to
briefly operate although no water is drawn off.
DHW mode will be suppressed until the DHW
temperature sensor detects if the water
preheated by solar energy has reached the
desired DHW temperature.
▶ Set the DHW mode delay according to the
system conditions.
After hot water has been drawn, the device
remains in DHW mode for the set time.
With thermal disinfection activated, when
drawing hot water the water is heated 70 °C for
a duration of 10 minutes.
After 10 minutes or after drawing hot water 3
minutes long, the thermal disinfection ends
automatically.
Short waiting time in comfort mode, when
domestic hot water is extracted. The device
therefore switches on, even if no domestic hot
water is extracted.
▶ In order to save energy and reduce any flow
noise, set a low pump curve ( sec 13.5,
page 59).
• ON: Save energy: intelligent shutdown of
heating pump for heating systems with
weather-compensated controller. The
heating pump is only switched on if required.
Pump output at minimum heat output. Only
available with pump characteristic 0.
Pump output at maximum heat output. Only
available with pump characteristic 0.
The pump overrun begins at the end of the heat
demand by the heating controller.
