Pump switch OCTAL KRONOS ALTER 2000
It controls the operation of two pumps, alternating between them to operate whenever there is a demand for one pump (P1 turns off).
When there is a demand for two pumps (P2 also turns off), the second one activates after a 4-second delay.
The voltage at the pressure switches is 12 VDC for safety reasons.
The alternating operation is controlled by pressure switch P1 and is set higher than P2.
