Level-1V-2-AC		Controllable: 1 liquid level switch 1 pulse solenoid valve 1 pressure detection 1 liquid level switch Powered by solar energy, using 10 * 230mAh AA rechargeable batteries (batteries not included in the product), combined with ANC brand AC valve relay to control 24V AC valve. This extension needs to be equipped with a GG-002C host for operation.
Level-1V-2-Solar		Controllable: 1 liquid level switch 1 pulse solenoid valve 1 pressure detection 1 liquid level switch AC power supply, combined with ANC brand AC valve relay, can control 24V AC valve. This extension needs to be equipped with GG-002C host for operation

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 sensor (pressure gauge or pressure switch) can be installed behind the valve to detect when it is turned on/When the valve is closed abnormally, the host willcall the police.

4.Wireless communication is used between the host and all outdoor controllers. The outdoor controller can automatically relayComposed of wireless componentsNetwork andhostFarthest wirelesscommunicationDistance can reach2000Rice.

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 can work continuously for nearly a month on rainy days.

8. Can be used as an accessory for intelligent irrigation system GG-002C or IoT irrigation system GG-002D.

It can control one liquid level switch, one pressure gauge (or pressure switch), and one 1-3 inch solenoid valve.Powered by solar energy, orAC power supply.

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.
