operating set point
User adjustable setting 90°F (32.2°C) to 190°F (87.8°C) range;
factory default is 120°F (48.9°C). When the water temperature
sensed by the control system from the immersion Temperature
Probe reaches the Operating Set Point the control system will end
the heating cycle. A call for heat will be activated again when the
water temperature drops below the Operating Set Point minus the
1st Differential Setting.
Example: Operating Set Point is 120°F (48.9°C), the 1st Differential
Setting is 2°F (1.1°C) (factory default). A call for heat will be activated
when the sensed water temperature drops to 118°F (47.8°C).
