4.2 Wiring Instructions
The Suraielec WiFi Pool Timer supports controlling one or two separate loads at 120V or 277V. The internal module is detachable for easier wiring. Refer to the wiring diagrams below for proper connection. It is highly recommended to consult a qualified electrician for wiring to ensure safety and compliance with local electrical codes.
Note on 240VAC Devices: While the timer can control 240VAC devices by utilizing both switches for the two hot legs, it is crucial that both switches are shut OFF simultaneously when turning off a 240VAC device (e.g., a hot water tank). For dedicated 240VAC devices, consider models UBTW01A or UBTW01B which are designed specifically for such applications to ensure proper and safe operation.

| Device not connecting to Wi-Fi. | Incorrect Wi-Fi frequency (5 GHz), weak signal, incorrect password. | Ensure your router broadcasts a 2.4 GHz network and your phone is connected to it during setup. Move the timer closer to the router or use a Wi-Fi extender. Double-check the Wi-Fi password. Contact your internet provider to ensure your modem supports dual frequencies or to enable the 2.4 GHz band. |
| Appliance not turning ON/OFF as scheduled. | Incorrect schedule settings, power interruption, device offline. | Verify the schedule settings in the Smart Life App. Check the power supply to the timer. Ensure the timer is connected to Wi-Fi (check indicator light). |
| Manual ON/OFF buttons not responding. | No power to the unit, internal fault. | Check the main breaker and wiring connections. If power is present and buttons are still unresponsive, contact customer support. |
| Voice control not working. | Incorrect linking of accounts, device name not recognized. | Ensure your Smart Life account is correctly linked to Amazon Alexa or Google Home. Try renaming the device in the Smart Life App to something simpler. |
