2. Patch panel - Wikipedia

   en.wikipedia.org/wiki/Patch_panel

   A patch panel is a device or unit featuring a number of jacks, usually of the same or similar type, for the use of connecting and routing circuits for monitoring, interconnecting, and testing circuits in a convenient, flexible manner. Patch panels are commonly used in computer networking, recording studios, and radio and television.

3. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temperature. Rarely, hot water occurs naturally, usually from natural hot springs. The temperature varies with the ...

4. Bang–bang control - Wikipedia

   en.wikipedia.org/wiki/Bang–bang_control

   A water heater that maintains desired temperature by turning the applied power on and off (as opposed to continuously varying electrical voltage or current) based on temperature feedback is an example application of bang–bang control. Although the applied power switches from one discrete state to another, the water temperature will remain ...

5. Thermostat - Wikipedia

   en.wikipedia.org/wiki/Thermostat

   The illustration is the interior of a common two wire heat-only household thermostat, used to regulate a gas-fired heater via an electric gas valve. Similar mechanisms may also be used to control oil furnaces, boilers, boiler zone valves , electric attic fans, electric furnaces, electric baseboard heaters, and household appliances such as ...

6. Patch cable - Wikipedia

   en.wikipedia.org/wiki/Patch_cable

   A patch cable, patch cord or patch lead is an electrical or fiber-optic cable used to connect ("patch in") one electronic or optical device to another for signal routing. Devices of different types (e.g., a switch connected to a computer, or a switch to a router ) are connected with patch cords.

7. Thermostatic radiator valve - Wikipedia

   en.wikipedia.org/wiki/Thermostatic_radiator_valve

   A thermostatic radiator valve on position 2 (15–17 °C) Installed thermostatic radiator valve with the adjustment wheel removed A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.

8. Punch-down block - Wikipedia

   en.wikipedia.org/wiki/Punch-down_block

   Similarly, stranded wire can be used on punch-down blocks, but they are designed for solid wire connections. Marginal practices like these are strongly discouraged in large or mission-critical installations, because they can introduce extremely troublesome intermittent connections, as well as more-obvious outright bad connections.

9. Self-regulating heater - Wikipedia

   en.wikipedia.org/wiki/Self-regulating_heater

   For example, space heaters use heating elements much hotter than the room being heated. In these applications, a thermostat may be better able to sense and control the temperature of the item being heated. Nevertheless, a self-regulating heating element may still be used to keep the heating element from damaging itself or other parts of the heater.
