PV stable band (advanced function setting level): Page 170
This parameter sets the PV stable band width within which the PV display
color is changed.
• When the mode to link to the PV stable band is selected with the “PV
change color” parameter, the PV display color will change according to
whether the present value (PV) is lower than, within, or higher than the PV
stable band, as shown in the following figure.
• There is a fixed hysteresis of 0.2 (
°C or °F).
