- Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE:
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation.
This equipment generates uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
To comply with RF exposure requirements, a minimum separation distance of 20mm must be maintained between the user’s body and the device, including the antenna.
Product Description
The IoTHF (Model:IoTHF) provides a high-quality solution for high flow applications by remotely On/Off the high flow valve . It can be controlled via IoT-let portal in web browser or Mobile App. The valve is available in air operated (normally Opened/Closed) version.
IOT HF WLS Interface connection
These are the items included in the package.
Overall set-up & connectivity
