▶ Set low pump curve to save energy and avoid possible
flow noise ( Chapter 12.5, page 71).
Pump ctr. mode • Energy saving
• Heat demand
• Saving energy: intelligent heating pump stop in
heating systems with weather-compensated
controller. The heating pump is only switched on
when needed.
• In case of a heat requirement: the flow temperature
controller switches the heating pump. When there is a
heat energy demand, the heating pump starts up with
the burner.
Min. output • 10...100 % Pump rate at minimum thermal output. Only available
with pump characteristic map 0.
Max. output • 10...100 % Pump rate at maximum thermal output. Only available
with pump characteristic map 0.
Pump overrun • 1...2...60 minutes
• 24 h: 24 hours
Run-on time of the heating pump: pump run-on time
begins at the end of the heat requirement.
Min.syst.pressure • 1...2...3 bar
Target pressure • 0.8...1.3...1.8 bar
Special function
Ventilation func. • Off
• Auto
•On
The ventilation function can be activated after
maintenance.
During ventilation, the following appears in the info area
of the standard display Ventilation func.
Siphon fill. prog. • Off (only permissible during maintenance)
• On, boiler min.
• On, heating min.
The trap filling program is activated in the following
cases:
• On, boiler min.: the appliance is switched on using the
On/Off switch.
• On, heating min.: The burner was not in use for at least
28 days.
• The operating mode is switched from summer to
winter mode.
The next time there is a heat requirement for heating, the
appliance is held at low output for 15 minutes. The trap
filling program remains active until the appliance has
completed 15 minutes of operation at low output.
During the trap filling program the following appears in
the info area of the standard display Siphon fill. prog.
3-WV mid. pos. • No
• Yes
The function ensures that the system is fully drained and
that the motor can be easily removed. The 3-way valve
remains at the centre position for approx. 15 minutes.
