Remark/restriction
▶ Measure the gas rate.
▶ Compare the measurement with the setting
tables ( page 55). 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.
Only available with DHW circulation pump ON.
With activated thermal disinfection, the DHW
cylinder is heated up to the set temperature set
for the thermal disinfection and kept at this
temperature for 20 min.
In comfort mode there is a higher DHW output.
▶ In order to save energy and reduce any flow
noise, set a low pump curve
( Chapter 13.5, page 55).
• 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.
