Heating and cooling elements worksheet
Heating and cooling elements control the temperature by switching single-stage heating equipment
such as electric heaters, or cooling equipment such as misters ON or OFF.
There are three types of heating and cooling element setups: standard, duty cycle, and advanced duty
cycle. Programming a standard element means setting the temperature set point. Programming a
duty cycle means setting the temperature set point(s) and the ON and OFF durations.
For more information, read Programming heating and cooling elements and duty cycles on page
