and stopping too frequently and reduces water hammer in long
pipes.

2. Select Stop delay time.
3. Set the Stop delay time.

6.7 Power-on delay

With this function it is possible to delay the startup of the pump after
the power supply has been switched on. The purpose is to avoid
disturbing the main power network which could happen if several
pumps start up immediately when the power supply is switched on.
6.7.1 Setting the power-on delay with Grundfos GO Remote
1. Go to Settings > Power-on delay.
2. Set the function to Enabled.
3. Set the time delay.

6.8 Dry-running protection

If the pump is running and the liquid level in the tank or pit becomes
lower than the dry-running level, the dry-running protection will stop
the pump to ensure that it is not damaged.
Dry-running protection is dependent on a feedback signal from a
level sensor installed in the tank or pit.
6.8.1 Setting the dry-running level with Grundfos GO Remote
1. Go to Settings > Level control > Dry-running level.
2. Set the dry-running level.
18
The dry-running level must be set to a value which
ensures that the pump is not damaged due to dry-
running. The specific level depends on the installed
pump type. See the installation and operating
instructions for the product.

3. Continuously press OK to confirm all other settings and to exit
the setup.

6.9 Multipump settings

The control unit enables start and stop of the two pumps alternately.
The pump with the lowest number of running hours is always
started first. The function ensures that the running hours of the
pumps are the same.
It is possible to set a time delay before the next pump is started.
6.9.1 Setting the multipump settings with Grundfos GO Remote
1. Go to Settings > Multi pump settings
2. Set Inter pump delay.
This is the starting delay between the pumps ensuring that they
do not start at the same time.
3. Set Max number of running pumps.
This is the maximum number of pumps which are allowed to
run at the same time.
6.10 Using the same level switch for the start and stop
level
1. Set one digital input to Start pump 1 or Stop. All other digital
inputs must be disabled.
2. Set a stop delay.
This will prevent the pump from starting and stopping too
frequently.

6.11 Antiseizing

The Anti-seizing function prevents a pump from choking or seizing
up as a result of deposits buildup. Anti-seizing is used in pits that
have had no inlet flow for a long period. The Anti-seizing function
ensures that the pump starts as often as set in Anti-seizing > >
Interval. The pump will operate for the number of seconds
indicated by the user.

active before the control unit initiates an action, such as starting or
stopping a pump.
6.12.1 Setting the signal-detection time with Grundfos GO
Remote
1. Go to Settings > Level control > Signal detection time.
2. Set the signal-detection time.
