2. HVAC control system - Wikipedia

   en.wikipedia.org/wiki/HVAC_control_system

   After the control of air flow and temperature was standardized, the use of electromechanical relays in ladder logic to switch dampers became standardized. Eventually, the relays became electronic switches, as transistors eventually could handle greater current loads. By 1985, pneumatic controls could no longer compete with this new technology ...

3. Thermistor - Wikipedia

   en.wikipedia.org/wiki/Thermistor

   Thermistor. A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor . Thermistors are categorized based on their conduction models. Negative-temperature-coefficient (NTC) thermistors have less ...

   Infinite switch. Energy regulator of an electric stove with a glass-ceramic hob. 1: Electric contacts (here closed); 2: Bimetal; 3: Heater for Bimetal. An infinite switch, simmerstat, energy regulator or infinite controller is a type of switch that allows variable power output of a heating element of an electric stove.

6. Motor controller - Wikipedia

   en.wikipedia.org/wiki/Motor_controller

   A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical faults.

   en.wikipedia.org/wiki/Glossary_of_HVAC_terms

   Glossary of HVAC terms. HVAC (heating, ventilation, and air conditioning) is a major sub discipline of mechanical engineering. The goal of HVAC design is to balance indoor environmental comfort with other factors such as installation cost, ease of maintenance, and energy efficiency. The discipline of HVAC includes a large number of specialized ...
