7.5 Scheduling
In some applications it can be useful to predefine a start and stop
schedule for the pump in order to lower energy costs.
The scheduling function allows you to customise the operating
time in several ways:
• Individual schedule for each day of the week: Total
customisation of pump operation cycles.
• 9-to-5 work week template: Inserts an adjustable template for
a typical work week. Suitable when no operation is needed on
weekends.
• Stop at night only.
• Summer mode: Presets the pump to stop operation in a
specific time period and automatically start again.
7.5.1 Scheduling operating periods
To customise the pump's operating periods, do as follows:
1. Connect the pump to Grundfos GO Remote. See section
7.2 Connecting the pump to Grundfos GO Remote
.
2. Tap the "Scheduling" menu.
3. Activate the scheduling function by tapping the grey
slide-button in the top right corner of the screen.
4. Choose the weekday for which you want to schedule the
pump performance.
5. Insert a time period by tapping the light grey perimeter of the
clock. Customise the time period by dragging the bar
clockwise or counterclockwise on the light grey perimeter. You
can insert more than one time period per day.
Delete a time period by dragging it outside the clock wheel.
You can assign more weekdays to the schedule by tapping the
weekdays in the bottom of the screen. Days are chosen when
they are shown as green.
7.5.2 Additional settings
"Use template"
This template allows you to select between two schedule
patterns, either "9-to-5 work week" or "Stop at night only".
The "9-to-5 work week" template inserts an adjustable template
for a typical work week.
"Summer mode"
This setting allows you to preset the pump to stop operation in a
specific time period and automatically start again. The pump will
automatically start up at low speed for a short period of time
every day to avoid blocking the rotor as well as sticky valves and
non-return valves. It is not possible to choose a time period that
lies further ahead than one year.

7.6 Activating and deactivating "Automatic night
setback"
To activate or deactivate "Automatic night setback", do as follows:
1. Connect the pump to Grundfos GO Remote. See section
7.2 Connecting the pump to Grundfos GO Remote
2. Tap the "Settings" menu.
3. Choose "Automatic night setback" and either enable or
disable the function. Press "OK".
When the pump is operating in either proportional-pressure,
constant-pressure or constant-curve control mode, "Automatic
night setback" can also be (de)activated in the "Setpoint" menu
available in the "Dashboard" menu via the "Automatic night
setback" icon:

When scheduling is activated, the pump will
automatically run for two minutes every 24 hours at
low speed to avoid blocking the rotor as well as
sticky valves and non-return valves.
In order to avoid damage to property and pipes, the
pump must only operate in "Summer mode" when
there is no risk of the pipes freezing.
