6. Level switches
Refilling of the storage tank is controlled with the aid of level switches.
Level switch = 1 :
The storage tank is immediately refilled if the level of the water drops below full. A
maximum quantity is always available.
The ‘IN” input can in that case be used as overpressure safeguard.
Level switch = 2 :
An alternative is to use two level switches for refill control. Here, the system is
switched on and when the low level is reached and switched off when the high level
is reached.
Advantage: the system is not switched on and off as often.
The ‘IN” input is used for connecting the low level switch.
The refill delay on the high level switch can be programmed between 1 and 99
seconds.
This step can only be programmed if 1 level switch is set.
