What is the normal operating temperature for the thermostat?
What is the tolerance of a thermostat? This refers to how closely the switch snaps on or off to the required operating temperature. In most cases this is + or 2C on opening temperature and + or 3C on closing temperature. That is, if you request a switch to cut out at 90C, then the tolerance of + or 2C means it can operate anywhere from 88C to 92C What is the differential of the thermostat? The differential is factory set between 8C and 10C. This means that if the operating temperature is 90C, then the ambient temperature around the device must fall between 8C and 10C before it starts operating again.
