1 - Operating Range: Range of temperature at which
disc thermostat performs switching function.
2 - Function:
• Opens - Normally closed circuit - opens within
specified temperature range.
• Closes - Normally open circuit - closes within
specified temperature range.
3 - Differential: Temperature drop below operating range
minimum necessary for disc to reset.
