RECEIVER DEVICE

Installation

NOTE

• Avoid positioning the receiver against or close to any metallic part to avoid any WI-FI transmission drop.
• Also, make sure that there is strong WI-FI signal reception at the place of product placement to ensure proper data transfer with the cloud. In case the WI-FI signal is weak boost it up through a WI-FI range extender.
• Install the device close to the unit to be controlled, in a way that the device can be dismantled if necessary. The product should be installed at a height of less than 1.5m high.
• Do not install the receiver where devices using radio frequencies as means of transmission are prohibited (Refer to local standards in effect).
• Do not install the receiver close to devices that may be affected by radio waves.
• Do not install the receiver in a damp environment (for example, a bathroom).

1. Disconnect the main power from the system.
   To ensure your safety, always make sure the main power is switched off before accessing the wiring.

2. Remove the cover from the receiver.

3. Mount the wiring plate to the wall or wall box.
   NOTE
   The plugs and mounting screws required are supplied.

4. Connect the receiver wiring.

   • Connect the H-LINK cable.
   • Place the cable through the orifice identified by marker 3.
   • Connect the power cable (L = Live; N = Neutral) (Tightening torque 0.50N·m)
   • Place the power cable in the cable guide identified by marker 1.

5. The cables must be positioned in the box’s cable guides to guarantee the pull-off strength.

6. Attach the cover of the receiver to the wiring plate.

7. Reconnect the main power to the system.

8. Download the CSNET Home application from the Apple Store or Play store. The application is also available on www.csnetmanager.com.
