FAQ

Question: How does night set-back work?

Answer:

Night set-back is activated (if configured to do so) through the feed temperature of the heat generator.

If the feed temperature sinks by more than 10-15°C for over two hours and the temperature drop is at least 0.1°C per minute.

The pump switches back to normal mode immediately when the feed temperature increases again by 10°C.

Night set-back only functions if the pump is installed in the flow pipe of the heat generator.
