Hi! Welcome to product review by Robojax.
My name is Ahmad Shamshiri presenting this tutorial from Canada. this tutorial we
are going to learn how we can use this W3002 temperature controller from DIYMore
to control AC or DC load and use this as a heater control or cooler control an
AC load and wiring and I'll show you how to control an easy load and including
the wiring let's get started with this. DIYMore has a release these two products the
DM-W3002 – both of these are exactly the same but the operating voltage is different.
As you
can see this available at 12 volts and this is 220 volts. It seems also they have 24 volts
version. you can use it and heater control or a cooler control so in both cases it can be
programmed and set also you can have a time delay between the heating and cooling if you
want have some kind of delay before it turns off or some kind of delay before it turns on in
that case also it has a feature where you can set the tolerance or correct the temperature
if your temperature deviates from the value Hardware explained these two or one is DC what the other is AC
from outside you will not notice the difference so when you turn it around you will see that
this has been labeled as 220 volts and this has been labeled marked as 12 volts so there is 20
volts so there is 24 volts version I have three versions now let's open the AC version.
So we
have micro controller here this is easy to DC converter we have two wires here and this has
been labeled the red is the live wire this is the neutral wire or ground so this is a hot or
live wire and these two are this will be live or hot wire L or H and this is the neutral this neutral N
the black is the same if you pay attention from the top these two blacks are connected so when
you connect the AC enters directly exits back so this is the neutral and the live L also power this
but the life goes through the relay and exits this way. and this is the NTC temperature
sensor which is connected at this point So we can close it simply like that. Features explained and here we have with three buttons here's this is the AC version and that's that DC version but in terms of functionality they are exactly
the same so let's focus on this one now I have connected 12 volts and a temperature sensor
now shows temperature the room temperature which is 22.9 degrees Celsius
when I press this this shows a start or one temperature if I press this this shows the
other one so you can set your upper and lower limit and this is showing p0 if I press this
up it goes it becomes p1 p2 p3 and then it comes back to p0 if you wait a few seconds the
screen will return back to displaying normal temperature.
When I press this p0 press it
again it will display the start temperature this is the start temperature p0 press again so
temperature and we can set it for example to 65 so wait and it just goes back to the temperature
now if I press this, that's 65 the other one is 50 and to set that 50 that their top temperature
plus this SET P0 go P 1 and then press SET. when you press it now this is a stop temperatures after P1
when you press it that's the stop temperature let me do it again P1 and then here and then you
can change the temperature as you wish so I'm setting it at 50 and leave. now let's
go to p2 process SET, P0, P 1 and now P 2 when you go on P 2 this is when I process this is for
tolerance correction let's say the temperature that you're measuring is a little low or high
and you want to compensate it'll say one point two degrees or add or subtract so let's say
you want to add one point two degrees let's press SET 2 and then here and then 1.2
now one point two is added every time pressure that we are receiving one point two will be added
on top of it so it will compensate it and if you want to subtract (reduce)
it process go down until you see negative now that's subtracting from the temperature
so after a while (few months) you will see if this deviates from the temperature and shows the wrong time
pressure so that p2 is for this purpose.
Now let's go and remove the P2 to fix it back
I don't want to change it so when it is 0 there is no addition or subtraction
with that. Wait, now let's go to p3 p3 is for setting when I press SET this
is the time delay when the start or stop triggers it waits if it is 1 it will be
1 minute 2 minutes 3 minutes all of these value are as you can see it can have up
to 10 minutes it doesn't go up so what it means this is that when the temperature
reaches and the relationship turn on and off if it is 1 minute it waits one
minute before turning it on or off AC wiring explained to start preparing this for AC, I have
to warn you that when working with AC it's very dangerous you have to be very careful and
take a lot of precautions and every step the power must be disconnected before you work and
if you are unsure how to proceed with this seek help from a professional.
Now in order to turn
on and off something this is my extension code this is the flag this is in Canada and the US
we have this type of plug. get in a wire and extension cord something like this and this
will go to the wall and cut it somewhere here which I have done and in US and Canada we have
the plaques are different so we know which one is live and which one is neutral a small one in
Canada the small one is the live L one and if I put it here you will see that this I've already
put it so this small one is the life or hot and I've labeled it so I don't make mistake now I'm
going to this one that goes from to the wall I will solder it at these two plus and minus so I
don't want to make sure that live L is connected to the red and then neutral N is connected to
the black so this is for the input and then I'm going to connect this for my load at this
point yellow is alive and then black is the neutral.
I heard of soldered the wire here and
I put heat shrink sleeves so I will heat it up I'd also have connected this that I connect my load here at this point
live is connected to yellow Let me apply heat Ready and I can connect this
to the AC directly put this on I do know what is the temperature setting
but I'm going to connect a load here Demonstration of using it as cooler controller now let me test it with the cooler
for the cooler we will set the same way start at 65° and stop at 50° so
I will set p0 at 65°C let me press SET s p0 press it again now make it 65 zero
press it again make it 65° I'm holding it Now it's 65°.
P1 stop 50° so press SETs and go
up and then press this again and then make it 60 now it is set at cooler and you can check it
start 65° stop 50° I've shown here so because it's now 19 degrees is below this it's a cooler
that control system is not working so it will not work until the temperature reaches 65
when it reaches 65 it will start is he that starts then it will still work and cool it
down until it reaches 50 it will turn off now I'm applying some heat using my heat gun and
here I'm holding this here and so you can see it pay attention here so at 65 it turned ON it went way high
because it's too hot now and this will stay on until it reaches 50°C so we are
cooling it down this is our cooler or refrigerator so it should go down until
this is 50 I'm holding it with hand so it cools down faster now very quick
you will see at 50 it will turn off Demonstration of using it as Heater controller now I'm going for heaters now start move
here now start is 50°C is totally 65°C the same way with AC let's start set it as at 50, press SET P1
is start press it again and then set this to 50 50 and then go up that stop
this time said this to 65 now it is set of 65.
Now because this has heater controller
we want to keep the temperature between 50 to 65 meaning if the temperature is below the 50
it will be ON and it will keep going until the 65 it will stop. until the temperature
reached 65 now it's 37 and the heater must be on which is on now so let me heat it so
the temperature reaches 65 it will turn off At 65 turned off and it will stay off until
reaches 50 so if I hold this with my hands will cool it down quickly very hot now pay attention
at 50 it will turn on very quick so it's turned on Setting time delay now I'm going to show you the time delay.
So to
set the time delay we put a SET and go up until you see three and press this, now the time delay
is zero you can set up to 10 minutes these are all minutes and let's set it at 1 and press SET
and let me go to mode 1 and let's set this to 65 And press SET and then the
stopp temperature. I'm going to use it at 50 And exit I've said this now for cooler p0 65° if
I proceed you will see p 0 and then p 150 so that's p1 what it means is now this is
a cooler when the temperature reaches 65 it will start turning on and then when it
comes back at 50 it will turn off now at the starting point I have added a 1 minute
delay now will add up temperature reaches 65 it will not turn on immediately it will
turn on after 1 minute let me show you now as you can see that as you can see the temperature
is above 65 a if it goes below the value I
will try to just heat it up it take a minute as we keep this up above 65 and
over a minute we will see now it should be on but kinda counter as it started so as soon as one
minute reaches you will see that this will turn on You see one minute past and now
because it's above 65 degrees the cooler started turning ON and it
will stay on until it reaches 50°C degrees I'm holding it now with
my hand so it cools down quickly But for 50°, it turns OFF immediately it
doesn't wait for a minute it's just the delay before the start.
Pay attention
as soon as this reaches it will turn off I would like to thank my Patrons from Patreon.com Subtitle typed and corrected by Ahmad Shamshiri on Nov 26, 2020 in Canada I did my part to help you learn. now it is your turn.
