Product Features:

1.Powered by solar energy, ifyesIndoor applications,alsocan be usedACalternating current, orbattery

2.Can be manually opened with one click/Close the valve for on-site operation and maintenance.

3.A pressure switch or gauge can be installed behind the valve to detect the opening/Is there any abnormality when closing the valve.

5.The liquid level sensor is placed in the water tank or hydroponic and connected to the controller. When the liquid level reaches a low level, the solenoid valve is opened, and when it reaches a high level, the solenoid valve is closed.

6.canDisplay communication status，air temperature,Battery information. After power shortageautomaticallyClose the valve first,againShut down, waitcharge.Equipped with a solar charging circuit,Wait for the battery to charge to the working voltageAutomatically resume work afterwards.

7.This controller is an independent liquid level controller that can work continuously for nearly a month on rainy days.

Can connect 1 liquid level switch sensor, 1 pressure switch or pressure gauge, and 1 1 to 3-inch pulse solenoid valve. Made of 12V/230mAh nickel hydrogen(Rechargeable)，Battery pack power supply, solar charging;It can also be powered by alternating current or batteries. The pressure switch styles are different, and the actual purchase shall prevail.

Note:

• The recommended length for the pressure switch extension cable is within 50 meters.
  

• The recommended length for the extension cable of the liquid level switch is within 50 meters.
  

• The recommended extension length for moisture sensors (except 005) is within 50 meters.
  

• The recommended length for the extension cable of the solenoid valve is within 20 meters.
