The bonehead mistake is that they’ve converted the +- 35F to actual C temp instead of range. Also suggesting a +-35F range in thermostat opening temp is obviously just plain wrong.

The degrees differential between C and F are 1.8. Therefore the 2 degrees C would be plus or minus 3.6 degrees F. Ran into the problem of having to add 32 degrees to any conversion between the two scales. This is what happens when Chemists (Celsius/Kelvin) try to have a battle of wits with engineers (Farenheit/Rankine). Sometimes the engineers can't see the obvious error.
The formula for coversion is degrees C times 1.8 plus 32. Therefore to covert C to F for a boiling point (at sea level) 100 degrees C multiplied by 1.8 and then add 32 for a result of 212 degrees F. In the case of looking at ONLY a delta between scales the 32 degrees from 0 can be ignored. Sometimes you can confuse the simple things.
