SUMMARY OF ALL EXPLANATIONS PROVIDED | ||||
---|---|---|---|---|
5 +4 | see explanation |

not more than see explanation Explanation: The contacts can be set to close at any temperature between 50C and 100C. Let's assume they set them to close at 60C. The temperature rises to 60C, the contacts close (which presumably stops the heating) and the temperature starts to fall. The contact is required to re-open somewhere between 59 and 50. I.e. within a range of 10 degrees below the set point. |
