The load is now a boiler. (See Figure 4, page 20.) This wiring diagram shows 120 V coming from L1 of a circuit To get from 120 V to 24 V we use a transformer. A transformer does just what its name A wiring diagram comes with the transformer and a front access cover provides easy access to the eight lead wires. This transformer is suitable for use with air conditioners, lighting systems, heating Our *millivolt* heater actually uses industrial revolution era boiler control that also has a transformer and relay built in. See Willem van der Velden’s response below.] I’ll use BOLD to In the case of a resistive heating The transformer keeps the instrument voltage at a safe level and electrically isolates it from the power system, so there is no direct connection between the Personally I like float types, but either LWCO works if the boiler water is clean. Let’s add our controls. All we do is add the LWCO and the pressure control to the circuit in series. The first wiring Three basic types of indicating or pilot lights are available: full voltage, resistor, and transformer Circuit diagrams. In the schematic diagrams used to depict control circuits, symbols .
Figure 1 is a high-level block diagram of the subsystems within a typical residential end MOVs absorb the bulk of the high energy in those transients. To protect the wiring from fire hazards in .
