If an increase rate of PV is larger than that of SV, the countdown begins after SV reaches SV3.

Step time (H/MP

0 or 3): The program steps proceed in accordance with the time set for each step.
Time countdown begins regardless of the statuses of PV and SV values and a step proceeds to the next
one upon set time elapsed.
Soak time 1 (H/MP

1 or 4): When a PV value falls within the set wait range, time countdown begins.
Judgment is made with a set SV value even if a ramp is set. A step proceeds to the next one after the
countdown begins and the set time is elapsed.
Soak time 2 (H/MP

2 or 5): Time countdown is executed within a set wait range (①

③).
The countdown is halted while a value is out of the wait range. The countdown continues when the
value comes back within the range. Judgment is made with a set SV value even if a ramp is set. A
step proceeds to the next one after the countdown begins and the set time is elapsed.
Note If the soak time 1 or 2 is selected, the countdown begins based on comparison of the PV value
with the SV value. The comparison of the PV value with SV* (*

1 to 8) is executed within a
common wait range (WAIt).
Note The countdown generally begins based on the comparison between the PV and SV values; however,
the countdown begins when the current SV value

SV* (*

1 to 8) is established if the ramp
function is used. No countdown is executed during temperature varying.
Note The ramp function cannot be used if a step time (H/MP

0 or 3) is set.
Note SV3: The control setting value is only for the purpose of explanation but not actual setting for the
main body.
