XMZ-TB20 Operation Instructions:

1. In gear mode, the gear can be adjusted within the range of 1 to 10 gears;
2. In temperature control mode, the set temperature can be adjusted within the range of 8~36
3. The gear of the control switch changes with the temperature inside the cab. When the temperature rises or falls, the control switch will automatically adjust the operating gear to quickly reach the set temperature, making the heater run more intelligent and economically.
4. When a fault occurs during operation, the control switch will display a flashing window to display the fault code, making it easier to find the fault more accurately and intuitively.
