In this section, set the following parameters by using three digits (first and second digits, and first decimal place) of each parameter
on the control panel data display.
• “Temperature range warning temperature setting” (Use the first and second digits.)
• “Temperature range warning reset temperature setting” (Use the first decimal place. Active only when “Warning” has been set.)
∗
1: When the first digit of the “temperature range warning operation setting” parameter of
Group A
is “4” or “5”, this parameter is inactive because
the warning status will not be automatically reset. (Enter any number from 0 to 9.)

When Tank liquid temperature [Th4] is 15
˚
C or lower, the compressor stops. (Warning)
[When Tank liquid temperature [Th4] becomes 17
˚
C, the warning status will be automatically reset.]
When Tank liquid temperature [Th4] is 35
˚
C or higher, the compressor stops (FH alarm), and the 30X relay output
turns ON.
When Tank liquid temperature [Th4] is at least 5
˚
C lower than the room temperature [Th3] (or machine temperature
[Th5]), the 30X relay output turns ON.
When the difference between room temperature [Th3] and Tank liquid temperature [Th4] becomes 4
˚
C or less, the
warning status will be automatically reset.
When Tank liquid temperature [Th4] is at least 5
˚
C higher than the room temperature [Th3] (or machine temperature
[Th5]), the 30X relay output turns ON.
When the difference between room temperature [Th3] and Tank liquid temperature [Th4] becomes 3
˚
C or less, the
warning status will be automatically reset.
