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  ②  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.
