Three patterns of a program consisting of up to 10 steps

Before inputting a
program
A program pattern must be registered (input) beforehand to start a
program operation.
① Confirm the number of steps, temperatures for each step, and time
on the program preparation sheet on pages 29 ∼ 30 in the
operation manual.
② Confirm the heating and cooling capacity of the device. Time
needs to be set within the heating and cooling capacity of the
device.
For a device having a cooling or heating capacity of 3℃ for every
ten minutes, for example, it requires about 35 minutes to lower or
raise by 10℃ from the given temperature.
③ Make sure that the controller has an unused pattern that meets the
number of steps to be programmed.
However, when you want to use the repeat function, the number
of steps to be repeated can be deducted from the number of
steps for the unused pattern.
Useful function
You can use the useful repeat function when you want to repeat the
same program steps. See page 28 for how to use the repeat
function.
