Red wire for power 24h. See the diagram below for what each wire controls on your system. The wiring diagram will show the circuit students will wire in wiring devices and wiring a wall section.
There are three basic types of circuit schematics used in hvac today.
This exercise includes topics related to hvac systems and incorporates material presented in the electric heating controls for air conditioning and reading electrical schematic diagrams study units. I show where the wires go at the thermostat the color code then down at the furnace control board. The wiring diagram will show the circuit students will wire in wiring devices and wiring a wall section. Central heating wiring diagrams wiring diagrams system wiring diagrams y plan system schematic showing flow from boiler to y plan or mid position diverter valve and then onto heating or hot water circuit.
