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.
• Press the operating knob.
The display (7) shows the current temperature in °C
and flow in m³/h.
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:
m³/h
°C
m³
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.
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.
