The FLOW
LIMIT
function can be combined with the following
control modes:
• Prop. press.
• Const. press.
• Const. temp.
• Constant curve.
A flow-limiting function ensures that the flow never exceeds the
entered FLOW
LIMIT
value.
The setting range for FLOW
LIMIT
is 25 to 90 % of the Q
max
of the
pump.
The factory setting of the FLOW
LIMIT
is the flow where the
AUTO
ADAPT
factory setting meets the max. curve. See fig. 27.
13.5 Automatic Night Setback

Home > Settings > Automatic Night Setback
Automatic Night Setback
To enable the function, select "Active" with or and press
[OK].
Once Automatic Night Setback has been enabled, the pump
automatically changes between normal duty and night setback
(duty at low performance).
Changeover between normal duty and night setback depends on
the flow-pipe temperature.
The pump automatically changes over to night setback when the
built-in sensor registers a flow-pipe temperature drop of more
than +18 to +27 °F (-8 to -3 °C) within approx. two hours.
The temperature drop must be at least 0.18 °F/min (0.1 °C/min).
Changeover to normal duty takes place without a time lag when
the temperature has increased by approx. +18 °F (-8 °C).
