The precise control of boiler thermostat directly affects energy consumption and safety. This article focuses on the core debugging steps to help you complete the operation quickly.


Core preparation before debugging
Safe power off: disconnect the main power supply of the boiler and ensure that the operating area is dry and free of debris
Confirm the equipment: check the type of thermostat (mechanical/electronic/intelligent), check that the wiring is firm and the shell is not damaged
Required tools: prepare screwdriver, multimeter, thermometer, and check the parameters in the user manual


Key parameter settings
Temperature setting
Range setting: set the upper and lower limits of temperature according to demand (18-25℃ for home heating and 3-5℃ for industry)
Temperature difference adjustment: 2-3℃ for home and 3-5℃ for industry to avoid frequent start and stop of the boiler
Mode selection
Prioritize automatic mode: automatically control the start and stop of the boiler to facilitate observation of the control effect
Turn on energy-saving mode (intelligent): optimize the operation strategy and reduce energy consumption
Sensor calibration (electronic/intelligent): optimize the operation strategy and reduce energy consumption Intelligent type)
Use a thermometer to compare the actual temperature with the displayed temperature, and enter the menu to calibrate the deviation


Core function test
Power-on check
After power-on, confirm that the display lights up and the button operation responds sensitively
Temperature control test
Heat-up: Increase the set temperature and observe the boiler starting heating and upper limit stop
Cooling: Lower the set temperature and confirm the boiler restart heating function at low temperature
Alarm test (if any)
Simulate over-temperature, low temperature or sensor failure, and check the alarm prompt (buzzer/light)
Key finishing actions
Parameter review: Check the set parameters and tighten the wiring terminals
File records: Register the debugging date, parameters, test results and problem handling measures
