5.7 Summer Switching
(Only for temperature sensor)
With this feature you can activate the summer switching and adjust it to your needs. As
mentioned before, it is possible that the water temperature exceeds the nominal
temperature. In this case the substrate heater would remain switched off and there would
be no circulation in the substrate.
By activating the summer switching feature, the floor heating is operated in such a way that
the water temperature is not significantly increased. The summer circuit is switched off by
default.
After you have activated the summer switching with Yes, you can adjust the Intensity of the
summer switching (5-30).
This number corresponds to the operating time of the substrate heater in minutes at a
temperature exceeding of 1 °C. The operating time is calculated by the controller depending
on the temperature exceeded.
Note
Noctural set-point = Set-point + Noctural change
