That's just not being right . . . lets just see if we can correct for that injustice.
With your forthcoming info, with those mystical and magic numbers I am seeing a spec of 80 degrees centigrade and a 20 degree differential swing.
So would it seem that those two temperature thresholds given below, will be properly fitting your situation with a Katz heater.
The units thermal snap disc, in its mechanical mounting, is sensing heat temperature change until a threshold of 80 degrees C / or / 176 degrees F is reached and the
thermostat disc clicks to an open circuit, and then the unit is without power until it cools down to 60 degrees C / or / 140 degrees F and the thermostat clicks to a closed circuit again to recycle and heat
up the water again.
Check out this units specs in the center left of this data sheet:

These units are only $6.87 a copy . . . . . .with merely 805 of 'em left in stock. (Eat yer' heart out 5 Star)
If your Katz unit is being the circulating tank heater type , this thermo units switching capability can handle up to the Katz 1000 watt heating unit
and that Katz units temp is doing its switching off at 175 F and then kicks back in after dropping down to the 135 F cool down threshold , certainly thats close enough.
