1. Introduction
The Beok BOT-R8W-WIFI Smart Thermostat is designed to provide intelligent temperature control for gas-fired wall-hung boilers. It functions by comparing the ambient room temperature with your set temperature, optimizing boiler operation to ensure comfort and energy savings in your home. This thermostat features a mirror LCD display and supports both battery and USB power options, along with smart home integration.
2. Setup
2.1 Power Supply
The thermostat can be powered by either AAA alkaline batteries or a USB-C connection. For continuous display and optimal functionality, USB-C power is recommended.
- Battery Power: Use 3x AAA batteries (not included). To conserve battery life, the screen will dim and turn off after 5 seconds of inactivity.
- USB-C Power: A USB port on the side allows for hassle-free wall mounting and keeps the screen always on. Vibration wake times can be set via the app.
2.2 Installation Steps
- Remove the mounting plate from the thermostat unit.
- Fix the mounting plate securely to the wall using the provided screws.
- Connect the boiler wires to the terminals on the mounting plate according to the wiring diagram.
- Attach the thermostat unit to the mounted plate, ensuring it clicks into place.
2.3 Wiring Diagram
The thermostat is designed for gas boilers and does not require an AC power connection for installation. Most boilers connect to the COM and NO terminals. Some specific boiler types may require connection to COM and NC terminals. Refer to your boiler's manual for specific wiring requirements.

4. Maintenance
To ensure optimal performance and longevity of your thermostat:
- Clean the display and casing regularly with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Ensure the battery compartment is free from dust and corrosion if using battery power. Replace batteries promptly when the low battery indicator appears.
- Keep the thermostat away from direct sunlight, drafts, or heat sources that could affect its temperature readings.
5. Troubleshooting
Refer to the table below for common issues and their solutions:
| Common Failure Phenomenon | Treatment Method |
|---|---|
| Cannot turn it on | Check if the rear shell is firmly installed. Ensure batteries are correctly inserted or USB-C power is connected. |
| LCD garbled code or incorrect temperature reading | Ensure proper wiring connections. If the issue persists, try restarting the device. |
| Thermostat loses settings after power outage (even with batteries) | Ensure a stable power supply. If using batteries, they primarily power the display and basic functions. For persistent memory, a continuous USB-C power connection might be necessary, or re-syncing with the app may be required. |
| Unable to connect to Wi-Fi | Ensure your Wi-Fi network is 2.4GHz. Check Wi-Fi password. Make sure the thermostat is in connection mode (blinking Wi-Fi icon). Try restarting your router and the thermostat. |
