AT (Auto Tuning)
・If AT is performed by FIX (constant value control), AT monitor LED blinks and light is put out by termination or
intermediate release.
・When auto tuning is ended in inclination step or chosen all PID(s), it is in standby state until one pattern is completed.
Then lights up, then puts out when one pattern is completed.
When AT is not completed within 1 pattern, AT conducting is released when one pattern is completed.
・Even in inclination step, AT is performed if it is in HOLD state.
AT at the time of 2 output specification is as follows.
At the time of heating / cooling operation and cooling / heating operation = OUT1, OUT2 common - PID value
At the time of heating / heating operation and cooling / cooling operation, only OUT1 performs AT.
OUT 2 output while performing AT is 0% or output limiter lower limit value.
