I am not going to try and trick the system by randomly throwing switches on. The temp cannot be both above 80 and below 50 at the same time, so the switching contacts on the thermostat will advance and recede in order of temperature setting.
Assumptions We will assume for testing purposes that the thermostat is working correctly, and the basic laws of thermodynamics apply. (e) between 60 & 70 one heater is on (I), & (d) above 70 no heaters are on Special conditions If the temperature goes above 80 then an alarm light is triggered, and stays on (even if the temperature drops below 80!) until a reset PB is manually pressed The entire system has a Stop/Start pushbutton control to make the system operate (nothing works unless the system is first turned on, whether heaters or alarm). (b) between 50 & 60 two heaters are on (1,2). Operation of the heaters is as follows: (a) Below 50 all three heaters are on (1.2. So the first contact is true if the temperature is 50 or higher, the second 60 or higher, and so forth. A storage room has a temperature control system with three heaters, and a thermostat with four contact settings which activate at 50°, 60°, 709, and 80°. And, yes, I do have to keep repeating that because from past experience for some people it is just necessary that I do. I do not want drawings, PDF, DOCX's, or non-LogixPro500 made files.
