Could you let me know which two terminals that you connect 3 volt power supply to and is the power supply AC or DC. Thanks. Ray
It came without the wire diagram and the seller does not answer the questions on how to power the 12v. Tests done only with battery power showed that the equipment does not work.
The equipment is just wonderful! It does not require any power for the 12v solenoid valves and contactor coil because the two 1.5v batteries become the necessary 12v. As I did not understand the operation of the equipment, I did an injustice with the initial assessment, but I only did it because the seller took too long to clarify my doubts about the solenoid supply.
