HELP!!!!!!! can someone look ove my project

I have attached what I came up with
A room must be maintained between 20 and 30 degrees C using a combination of an AC and Heater, four thermostat: T20, T22 ,T28 and T30. If the temperature reaches 30 C, which activates T30. the AC must be energized and kept until the temperature decreases to 28C which deactivates T28. If the temperature reaches 20C which deactivates T20, the heater must be energized and kept energized until the temperature increases to 22C which activates T22. A master switch must be turned on for both the AC and heater to operate. Use latch and Unlatch instructions, Assign sequential addresses to the input and output starting from bit 0

Close. Since this seems like a class test / exercise, the only thing I'll comment on is why are you using all N.C. thermostat contacts in your logic?

I wasn't asking for the answer!!!!!!!!!!!! I'm learning here

Well, now that you have yelled at theDave2. What exactly is your question then?

Stu.......

chbryan34,

you have made an effort to do the program, posted your work, and askksed for help.
the dave2 has given you a clue in regards to your program.
this was an attempt to get you to think abou what you've done.

take your program, and what you put on the website.
sit down and read what you have typed.
work out your logic line by line, not all at once.

regards,
james
