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.
