turn-on level
The fluid flow rate would be regulated to keep the outlet temperature within a range of 10–15 ◦C above the minimum temperature. At the end of the day, when the temperature out of the collector dropped below the turn-on level, flow again stopped.

What does "turn-on level" mean in this context? Can we use turn on as an adjective?

Thanks a lot in advance

Answer

Turn-on seems to be an adjective here. In the context it is simply saying that there is an specific level that turns the flow on or off. Of course it's hard to be sure unless you have read the whole article.
