Temperature control :-

Temperature control is a process in which change of temperature of a space (and objects collectively there within) is measured or otherwise detected, and the passage of heat energy into or out of the space is adjusted to achieve a desired average temperature. Air-conditioners, space-heaters, refrigerators, water-heaters, etc. are examples of devices that perform temperature control. These are often broadly classified as Thermostatically Controlled Loads (TCLs).

Pressure Control :- Pressure control (PC) is a mode of mechanical ventilation alone and a variable within other modes of mechanical ventilation. Pressure control is used to regulate pressures applied during mechanical ventilation.
