7.7 Eco schedule
In some applications it can be useful to predefine a start and stop
schedule and apply an automatic temperature setback function in
order to minimise consumption, and thereby energy costs.
With the Eco schedule you can configure start and stop intervals on
a weekly basis as well as set single events.
This function can only be set via Grundfos GO Remote.
7.7.1 Scheduling Eco periods
Grundfos GO Remote menu:
Main menu
> Settings > Eco functions > Eco schedule

Activate the scheduling function by pressing the grey slide-
button in the top right corner of the screen.

clock.
4. Customise the time period by dragging the bar clockwise or
counterclockwise on the light grey perimeter.
5. You can assign more weekdays to the same schedule by

chosen when they are shown as green.
You can insert up to four time periods per day.
Delete a time period by holding and dragging it to the wastebin
in the top left corner.
6. Press Save to complete the setup.
Specify whether MIXIT must run according to a temperature
setback or shut down in the defined Eco period(s).
7.7.2 Setting temperature setback and system turn off
Grundfos GO Remote menu:
Main menu

A temperature setback can be defined for the period in which MIXIT
runs according to
