• Page 5: Product introduction provides an overview of the WT301&WT302 touch screen room thermostat designed for air conditioner applications. The thermostat manages fan and valve operations by comparing environmental temperature with a pre-set desired temperature. It ensures optimal comfort and energy efficiency through proactive management and automatic control. Wireless detection and easy configuration allow for reliable room temperature optimization. The device is compatible with standard LoRaWAN gateways for real-time environmental monitoring. Key features include automatic and manual temperature adjustment with time-controlled regulation. It supports two pipes and 3-speed fan coil systems, with options for On/Off relay or 0-10V valve control. The thermostat offers a programmable schedule for maximizing comfort and economy. It features high accuracy of 0.5°C for precise indoor temperature control. The sleek design includes an LCD screen with four-color LED and capacitive touch buttons for enhanced user interaction.

• Page 7: Wiring diagrams for WT301 and WT302.
• Page 8: Installation locations suggest placing the WT30x thermostat about 5 ft. above the floor in an area with good air circulation. Avoid installing the device near hot or cold air ducts, in direct sunlight, in dead spots or drafts, in areas that do not require conditioning, close to concealed chimneys or pipes, near metal objects that affect LoRaWAN transmission, in areas with many electromagnetic interfaces, or in places prone to strong vibrations or physical shock. WT30x is suitable for installation within a standard 86mm pattress box or a European 60mm pattress box. Ensure the circuit of all related systems is shut off before installation. Connect corresponding wires to the appropriate terminals of the WT30x device.
• Page 9: Remove the LED screen from the mounting plate by pushing the LED screen assembly. Fix the mounting plate into the wall with mounting screws. Fix the LED screen back to the mounting plate. WT30x supports configuring the device via 5 buttons. The guide will use specific names to indicate every button.
• Page 10: Power on/off: Press the POWER button to turn the thermostat on/off. When the button lights green, the thermostat is off; when the power button is off, the thermostat is on. Switch system mode: Press the MODE button to switch among heating, cooling, and ventilation. In ventilation mode, the valve is off but the fan runs. Switch the fan speed: Press the FAN button to switch the fan speed among auto, high, medium, and low. Adjust manual & programmable mode: Press and hold the MODE button to toggle between manual and programmable modes. Manual mode allows for manual temperature adjustments using the UP and DOWN buttons. Programmable mode controls the temperature according to a weekly schedule. In programmable mode, the UP and DOWN buttons will not work.
• Page 11: Adjusting/Setting the Clock Press and hold the “MODE” button to enter adjustment mode. The device will save your settings automatically after a few seconds of inactivity. Locking the Thermostat Buttons Press and hold the UP and DOWN buttons together for 3 seconds to enable/disable button lock. The lock mode can be set in advanced settings. Adjust the Weekly Programmable Schedule WT30x supports adding up to 6 time periods and 6 temperature values during weekdays, Saturday, or Sunday. After completing all settings, click MODE button to confirm and exit the schedule settings. Default settings of programmable schedules are provided for weekdays, Saturday, and Sunday. Advanced Settings Press the POWER button to turn off the thermostat, then press and hold MODE and FAN buttons together for 5 seconds to access advanced settings. These advanced settings will take effect after turning on the thermostat.
• Page 12: Function settings and options include temperature compensation ranging from -9°C to 9°C. When room temperature reaches the set temperature, the fan can either turn off or keep running at low speed. Button lock settings allow for half lock, where all buttons except the power button are locked, and full lock, where all buttons are locked. System mode selection includes cooling, heating, and ventilation options. Minimum and maximum set temperatures are 5°C and 35°C, respectively. Time mode can be set to either a 12-hour or 24-hour clock. Display modes include showing both set and room temperatures or only the set temperature. Keycard functions include energy-saving modes for heating and cooling when the keycard is not connected. Daytime display brightness can be adjusted, with the daytime defined as the period between 6:00 and 22:00. Night display brightness is also adjustable.
• Page 13: The valve will start cooling when room temperature is greater than the set temperature plus the dead zone temperature. It will start heating when room temperature is less than the set temperature minus the dead zone temperature. Report interval can be set from 1 to 60 minutes, with a default of 1 minute. Keycard function can be turned on or off. Time zone can be set from -12 to +12, with 12 indicating UTC+0. Internal or external NTC input sensors can be used for temperature readings. External temperature data can be utilized via downlink command. The proportional band (P value) determines the change required in ambient temperature for the output to reach 100%. The P value can be adjusted from 1 to 10, with a factory default of 2. A larger P value results in a greater change in valve output.
• Page 14: Heat mode allows output between 0-100% when the ambient temperature is below the set point. Cool mode allows output between 0-100% when the ambient temperature is above the set point. The I value sets the integral action time from 0 to 100%, affecting the control loop's stability and responsiveness. The integral action time can be adjusted from 1s to 60s, with a default value of 40s. WT30x does not support configuring LoRaWAN settings; customization must be done before purchase. Device EUI is the unique ID of the device. The default App EUI is 24E124C0002A0001. The application port is used for sending and receiving data. OTAA and ABP modes are available for join type. OTAA is one of the join types supported.
• Page 15: Application key and network session key are essential for device communication. Appkey is used for OTAA mode, while Nwkskey is for ABP mode. The device address and application session key are critical for ABP mode. LoRaWAN protocol version is V1.0.3, indicating the communication standard used. The device operates in Class C mode, allowing continuous listening for downlinks. RX2 data rate and frequency are specified for receiving downlinks. The device will resend data if it does not receive an ACK packet from the network server. Adaptive Data Rate (ADR) can be enabled or disabled, affecting data transmission. Transmit power and spread factor settings are crucial for device performance. Device data format includes start, ID, data length, data, and checksum.
