This is minimum load adjust used during
a water heater temperature calibration.
It adjusts the controller’s linear offset
relative to the temperature of the BTU
transmitter sensor. Similar to SEnS it is
adjusted when the controllers output is
less than 30%.
This is the Low Limit Temperature. It is
the minimum value that the Setpoint,
(SetP), can be set to.
This is the High Limit Temperature. It is
the maximum value that the controllers
setpoint, (SetP), can be adjusted to.
This is the Proportional Band in °F for
the feedback of the controller. This
feature is useful in correcting outlet
temperature errors when under steady
load conditions.
This is the integral rate, in minutes, for
the feedback of the controller.
This is the derivative rate in % / .1°/sec.
This is used to adjust the response time
to temperature changes at the outlet of
the heater.
