Temperature-controlled mode
• Use the operating knob (8) to select the "Operating
mode" menu and then select TEMP.
• Set the minimum temperature and the minimum flow
in the menu items.
Note: Selection ranges:
• Temperature: 50–70 °C
• Flow: 0.0–2.0 m³/h (version 1-4) or 0.0–3.0 m³/h
(version 1-6)
Note: The pump controls the speed so that the
set minimum flow is maintained up to the maximum
delivery head. This prevents stagnation and the growth
of Legionella in the piping.
• Press the operating knob.

The display (7) shows the current temperature in °C
and flow in m³/h.
Note: Depending on the size of the installation
and the number of ascending lines, noises may occur
while heating up. Select a volume flow and pipeline
diameter such that the flow rate does not exceed 1 m/s.
The following table shows the recommended minimum
flow per line relative to the pipe diameter, in order to
ensure a flow rate of 0.2 m/s per line:
