| Room temperature control system. Consists of Thermostat, furnace, thermometer & thermostat which compares desired room temperature. Thermostat uses difference between two readings to generate error signal is positive when the set point is higher than the actual temperature. (room is colder than desired) and negative when (room is hotter than desired). This functionality automatically maintains heating furnace at optimal levels. |
