About PV start
In start mode, when PV is chosen, and when PV is closer to the set point of Step1 than start SV,
wasting time is omissible.
「example」：PV at the time of "RST is 30℃, Start SV is 0 ℃, Step 1's attainment SV 100 ℃, Execution
time of Step1 is 60 minutes
Start at start SV, attainment time is 60 minutes.
When starts at PV, 100-30=70℃, therefore 60 minutes x70% = 42 minutes = 18
minutes' shortening
However, depending on the spatial relationship between PV, Start SV, and attainment SV, it may become SV
start or Step1 may be skipped.
