Appendix 1: Simple Explanation on the Function of Hysteresis
The controller relay activates when the set-point
is reached. In the reverse direction, it does not
de-activate when the value reaches the set-
point. Instead, it continues to be active till the
value reaches the amount set by the Hysteresis
band.
Appendix 2: Factory Defaults
Resetting the controller to factory default settings (See program P7.0) clears
all calibration data and most other setup functions.
The following settings will remain unchanged:
1.
Measurement range
2.
Temperature compensation mode (ATC or MTC)
3.
Temperature offset calibration value, if in ATC mode.
Conductivity Defaults
Conductivity range
Remains unchanged at last selected range
Set point 1
