Programmable Temperature & Humidity Controller
56
Condition Unit
GAIN < 1.0
With stronger derivative and integral controls than auto-tuned PID value, overall
response speed becomes faster but the hunting may be more.
GAIN = 1.0 Auto-tuned PID value is used as is.
GAIN > 1.0
With weaker derivative and integral controls than auto-tuned PID value, overall
response speed becomes slower but over shoot can be reduced for more stability.
●
Auto tuning gain(A/T gain)
1. Temperature range value
- The range is decided automatically by user's temperature setting range
2. Humidity range value
- The range is decided automatically by user's humidity setting range
3. Manual PID Number
- Setting range: 1~16
-If the numbers are set manually, only manually-set zones are referred.
PID zone consist of each 4 zones for temperature and humidity, total 16 PID zones are used for
temperature/humidity simultaneous control.
