24 Hour Heating Timer for RTC MIAC

[Enamul]

first I have to change the 16.00 - 23.00 time period to something like 16.00 - 22.00 so that I can test times tonight, is it quite easy to do ?

Yes, you can simply change 23 to 22. It is fine.

And could you put minutes in ie for eg 22.15 ?

With existing code you can't do that..I am modifying the code and post shortly to have that facility.

Hi Stuart

I have modified the code and now you can easily put start and stop hour and min both. You don't need to search for that to put now in the code. There is a calculation box in the beginning of the code..I put a comment where to put different period hour and min.
Please let me how you are getting!!

Thanks Enamul,

That will make it easier to test...

Hi Enamul,

I have just programmed the MIAC with these settings:

//Period 1
HOUR1_START = 21
MIN1_START = 35
HOUR1_STOP = 21
MIN1_STOP = 37
//Period 2
HOUR2_START = 21
MIN2_START = 39
HOUR2_STOP = 21
MIN2_STOP = 40
//Period 3
HOUR3_START = 21
MIN3_START = 42
HOUR3_STOP = 21
MIN3_STOP = 42


Q1 Lit up at 21.35 (first on period) and then stayed on ie the rest of the on off programs did not work.


Thanks
Acestu

[Enamul]

OK I see. I am checking the code why it's not working

[acestu]

Hi Enamul

This might help you, i programmed these times:

//Period 1
HOUR1_START = 21
MIN1_START = 53
HOUR1_STOP = 21
MIN1_STOP = 49
//Period 2
HOUR2_START = 21
MIN2_START = 54
HOUR2_STOP = 21
MIN2_STOP = 52
//Period 3
HOUR3_START = 21
MIN3_START = 57
HOUR3_STOP = 21
MIN3_STOP = 57

But Q1 never came on at all.

thanks

Hi Stuart,
If start hour and stop hour is same..in that case stop min must be higher than start min. Clock can't run reverse. I have corrected part of the issue. It will work now for period 1, 2 and 3 if they are like different slots of different hour..if they are in the same hour only period 1 will work..you can test that meanwhile I am modifying rest bit..

[Enamul]

Here is the code in which you should be able to set three periods in same hour to test the system. But please remember to put start min smaller than stop min for all three periods. Like
Period 1:
HOUR1_START=23
MIN1_STRAT = 34
HOUR1_STOP =23
MIN1_STOP = 36

Period 2:
HOUR2_START=23
MIN2_START = 37
HOUR2_STOP=23
MIN2_STOP = 39

Period 3:
HOUR3_START = 23
MIN3_START = 40
HOUR3_STOP=23
MIN3_STOP=42

Hi Enamul

Just tested code with

//Period 1
HOUR1_START = 23
MIN1_START = 19
HOUR1_STOP = 23
MIN1_STOP = 20
//Period 2
HOUR2_START = 23
MIN2_START = 21
HOUR2_STOP = 23
MIN2_STOP = 22
//Period 3
HOUR3_START = 23
MIN3_START = 24
HOUR3_STOP = 23
MIN3_STOP = 25



first period comes on and then off, then stays off ie other 2 periods do not work.

The reason I set the last period to same on /off time was to cancel that time period so it only comes on 2 periods (I thought I could Cancel a period like this)

Ok I will try last code you posted now

Thanks

Hi Enamul,

The last code I used:

//Period 1
HOUR1_START = 23
MIN1_START = 32
HOUR1_STOP = 23
MIN1_STOP = 33
//Period 2
HOUR2_START = 23
MIN2_START = 34
HOUR2_STOP = 23
MIN2_STOP = 35
//Period 3
HOUR3_START = 23
MIN3_START = 36
HOUR3_STOP = 23
MIN3_STOP = 37


The first period came on then went off, the second period came on and went off straight away before off time, and period 3 did not come on at all.

Thanks

Hi Stuart,
Thanks for the postings. It would not be possible to find out problem without Flowcode's strong simulation feature. I have made simple clock and test code in simulation. Now it's working fine.

[acestu]

Thanks Enamul,

That's great I will have a go at that now, I will let you know in a bit...

thanks

Hi Enamul,

I have just programmed the new code with these periods:

//Period 1
HOUR1_START = 17
MIN1_START = 55
HOUR1_STOP = 17
MIN1_STOP = 56
//Period 2
HOUR2_START = 17
MIN2_START = 57
HOUR2_STOP = 17
MIN2_STOP = 58
//Period 3
HOUR3_START = 17
MIN3_START = 59
HOUR3_STOP = 18
MIN3_STOP = 00

But as soon as I programmed it the Q1 light lit up at 17.52 which it shouldn't of done.

Thanks
Acestu

[acestu]

It has just gone off at 17.56

On at 17.57

off at 17.58

On at 17.59

Failed to go off at 18.00

Thanks
Acestu

[Enamul]

But as soon as I programmed it the Q1 light lit up at 17.52 which it shouldn't of done.

Can you please try once more? It shouldn't do that.

[acestu]

Hi Enamul, I have programmed a couple of settings this being the latest one:

//Period 1
HOUR1_START = 18
MIN1_START = 20
HOUR1_STOP = 18
MIN1_STOP = 22
//Period 2
HOUR2_START = 18
MIN2_START = 26
HOUR2_STOP = 18
MIN2_STOP = 29
//Period 3
HOUR3_START = 18
MIN3_START = 33
HOUR3_STOP = 18
MIN3_STOP = 35


However on every one even this one as soon as you program the miac the Q1 light is on, then it goes off at the first off time and carries on normally.

EDIT: just gone off at 18.22 (first off time)

Thanks
Acestu

Hi Enamul,

I have just done this set of periods:

//Period 1
HOUR1_START = 19
MIN1_START = 15
HOUR1_STOP = 19
MIN1_STOP = 17
//Period 2
HOUR2_START = 19
MIN2_START = 19
HOUR2_STOP = 19
MIN2_STOP = 21
//Period 3
HOUR3_START = 19
MIN3_START = 22
HOUR3_STOP = 19
MIN3_STOP = 25


And the same as soon as you program the code Q1 relay comes on and goes off at first off time.

thanks

Hi Enamul,

I have just been looking at the flowchart for the code, does this mean anything in my pic ?

[Enamul]

Ohh..I thought I put off there but it seems I put ON which is wrong.
Actually I am still at university..Can't look at the simulation file. It's good that you have noticed the issue.

[acestu]

No probs Enamul,

I tried disabling that miac relay on box, but it did not work.

thanks
Acestu

[acestu]

Hi Enamul,

I changed the MIAC command to relay off, but that did not work.

thanks
Acestu

[acestu]

Hi Enamul,

What are the variables rem1, rem2 and rem3 in the code please ?

thanks
Acestu

[Enamul]

REM1,2 & 3 is just to avoid send relay on command every time it comes to the decision true case.

I changed the MIAC command to relay off, but that did not work.

Relay need to be OFF there..I am checking in simulation now all the cases you have posted.

[acestu]

Thanks Enamul,

I was just trying to read the flowchart that's all, to see if I could figure out why the relay comes on straight away.

thanks
Acestu

[Enamul]

Hi Stuart

I have tested code in simulation...only that Relay ON was the issue. Other than that code works very nice for me. I have tested your time periods..

//Period 1
HOUR1_START = 19
MIN1_START = 15
HOUR1_STOP = 19
MIN1_STOP = 17
//Period 2
HOUR2_START = 19
MIN2_START = 19
HOUR2_STOP = 19
MIN2_STOP = 21
//Period 3
HOUR3_START = 19
MIN3_START = 22
HOUR3_STOP = 19
MIN3_STOP = 25

It worked fine for me..Here is the code I have tested.
