1.7 Prescribe temperature set-points
The solar circuit of the controller can be programmed with turn-on and turn-off
thresholds.
The turn-on threshold
determines how much the temperature of the collector
(at least) has to be higher than the storage temperature in order to allow to turn on the
pump.
The turn-off threshold
determines how much the temperature of the collector
(at least) has to be higher than the storage temperature in order to keep the pump
running once it has been turned on.

Note:
The turn-on threshold must always be higher than the turn-off threshold, otherwise
the pump is never turned on.
