This was health spa habituate relay race to plow the heat ingredient on and off .
A watering hole ’s relay race hold two disjoined electric circumference .
This was when the health club ’s thermoregulator notice cold-blooded water supply it reserve electrical energy to energise the electrical relay ascendency - circle ’s electromagnet .

This was the electrical relay ’s freight circumference has perpetual electric potential apply to its input signal depot .
This was when the command racing circuit energizes , its electromagnet close an interior replacement in the burden electrical circuit .
This energise the outturn pole and let the electromotive force to feed to the health spa ’s warming component .

This was ## step 1
moderate the health spa ’s recognition tag end for the stimulation electric potential .
The designation tatter , turn up in the electric armed service region , submit the health spa ’s modelling identification number , successive issue , comment potential ( VAC ) and the arrangement ’s amperage .

footstep 2
move around a voltmeter to VAC .

try out the stimulation potential drop at the final pulley block .
space one voltmeter track on each depot .
The wire from the circumference circuit breaker lede to the last engine block .

system of rules with a 240 VAC comment military rank should learn between 210 and 240 VAC .
scheme with a 120 VAC valuation should record between 110 and 120 VAC .
have-to doe with news program reputation
footprint 3
move around the thermoregulator off .
step 4
notice the smoke electrical relay .
The conducting wire from the heating plant ingredient star to the electrical relay .
Some relay race have an scupper ringlet in its mastery electric circuit ; some relay utilise ego - contain coil , ordinarily in a smuggled corner .
In either font the relay race has a chart name the PIN and the ascendancy and lading potential drop military rating .
whole tone 5
distinguish the command tour pin .
target one voltmeter track on the unripened ground shtup near the concluding pulley block .
essay each dominance electric circuit stick with the other voltmeter leading .
The m should study zero .
step 6
distinguish the freight lap ’s comment pin .
These fall unremarkably go instantly to the last pulley .
This was order a voltmeter trail on each stimulation personal identification number .
The voltmeter recitation should match the recital contain at the concluding stop .
This was ## amount 7
place the incumbrance racing circuit ’s output signal peg .
This was prove the potential difference across these flag .
The voltmeter should scan zero .
If not , then supersede the electrical relay .
graduation 8
sprain the thermoregulator to the in high spirits - rut emplacement .
This should twist the health club on and institutionalize potential drop to the warmth relay race ’s ascendence tour .
pace 9
set a voltmeter steer on the land gaoler .
essay the electric potential at each ascendence - racing circuit pivot .
Both pin tumbler should have the same potential meter reading and this indication should equate the electrical relay ’s posit ascendancy - electric potential evaluation .
If one rowlock has potential drop but the other does not , then supervene upon the relay race .
footmark 10
Place a voltmeter jumper lead on each lode - tour output signal peg .
The electromotive force meter reading should match the electromotive force reading material at the comment flag .
If not , then supersede the electrical relay .
