Notes:
1. The soft start time units can be set by the parameter PG10/SVGr, item No. 3 (see page
79). The factory default units are hour.minute.
2. The parameter is set for heating in the heating, cooling PID operation.
3. The Integral time I, and the Differential time d for cooling are automatically set to the
same values as these parameters for heating.
4. Refer to "3.5 Compensation for Control Responsiveness" on page 51 for selecting a
value.
