The intelligent toilet thermostat adopts the PID temperature control form. PID temperature control form, related to the characteristics of temperature control heaters, in a relatively confined space, usually can control the temperature at about 1 degree, only with solid-state relays, thyristor voltage regulation module, can control the temperature at plus or minus 0.1 °C. PID thermostat has been widely used for nearly 20 years, and its operating principle is that when approaching the set temperature, the appearance is based on the thermal inertia principle of the heater, and the on-off time or current and voltage of the heater are controlled, which can reduce the thermal inertia of the thermostat and achieve the purpose of precise control.
