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
