iPWM 2 mode:
In iPWM 2 mode, the pump speed is controlled according
to the PWM input signal.
Behaviour in the event of a cable break:
If the signal cable is disconnected from the pump, e.g.
PWM
% due to a cable break, the pump stops.
PWM signal input [%]
0-7: Pump stops (standby)
7-15: Pump runs at minimum speed (operation)
12-15: Pump runs at minimum speed (starting)
15-95: The speed of the pump increases linearly
from n
> 95: Pump runs at maximum speed
The pump venting function is activated by pressing and
holding the operating button (for 3 seconds) and auto-
matically vents the pump.
However, this function does not vent the heating sys-
tem.
A manual restart is initiated by pressing and holding the
operating button (for 5 seconds) and unblocks the pump
as required (e.g. after a long idle time in the summer).
The key lock is activated by pressing and holding the
operating button (for 8 seconds) and locks the pump's
current settings. It protects against undesired or unau-
thorised adjustment of the pump.
The factory setting is activated by pressing and holding
the operating button whilst switching off the pump.
When the pump is switched on again, the pump runs
using the factory settings (delivery condition).
