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 P8.0) 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.
