The role of classification of the thermostat

The temperature controller is used to detect  the compressor’s  start and stop ,solenoid valve off and control the damper’s size, which  maintained  the temperature at  a predetermined range, so as to achieve the purpose of controlling the temperature, which is divided into pressure and electronic two categories, the pressure one also called capsule-type temperature controller, which is characterized by simple structure, good performance and low price; While electronic one  has a negative temperature coefficient thermistor  as a sensor, electronic circuit control relay or thyristor temperature control,which is characterized by fewer mechanical parts, high reliability, high precision temperature control, easy to control  and complicately control the indoor temperature.
