How to choose the right thermostat?

Consider using the environment temperature range: according to the actual need to control the temperature range of choice. For example, temperature controllers for cold storage need to be able to measure and control temperatures as low as -20 ° C or even lower; The thermostat for the home heating system is usually in the range of 0 ° C -30 ° C. Environmental conditions: if you use a damp, dusty or corrosive gas environment, should choose waterproof, dust proof or corrosion resistance performance of the thermostat. For example, in humid environments such as kitchens and bathrooms, it is necessary to choose a temperature controller with a higher waterproof level.

Clear control requirements: control precision for requiring higher precision of temperature, such as laboratory, semiconductor manufacturing, etc., need to choose high control precision of temperature controller, can generally be accurate to + / – 0.1 ℃ or higher. For ordinary home or business environments, such as air conditioners, water heaters, etc., the control accuracy is usually able to meet the demand at about ±1 ° C. Load type and power: depending on the type of load to control (e.g., heating equipment, refrigeration equipment, motor, etc.) and power output size to select the appropriate type and capacity of the thermostat. If you are controlling a high-power heating furnace, you may need to choose a thermostat that has a relay output and can withstand high currents.

Focus on demand basic functions: to ensure that the thermostat basic temperature measurement, display and control functions. Some simple thermostats may only have the function of manually adjusting the temperature, while some advanced thermostats can achieve automatic adjustment and set different temperatures according to different time periods. Additional features: according to the actual demand considering whether to need additional features, such as data record function can help the user to see the temperature change history, alarm functions can be timely remind the user when temperature exceeds the scope, the remote control functions can be anywhere at any time by mobile phone or computer to control temperature.
