0: Relay J1 Alarm output; SSR Disabled, normally used for upper lower limit alarm trigger control.

1: Relay J1 PID controlled output: SSR Disabled. Contact controlled output.

2: Relay J1 as alarm output; SSR PID controlled 12 Volt output. Know as No Contact controlled output.

This controlled has 3 type of auto-tuning control methods already built-in.

0: Universal PID control suitable for increase/decrease fast speed of change of temperature application.

1: Gradual change PID control is suitable for applications that require steady change of temperature and speed of temperature change is not critical.

2: Fussy logic control suitable for system with oscillation and sensing signal delay.

P, I and d parameters control the accuracy and respond time of the temperature controller. Auto-tuning is recommended for user who do not familiar PID control theory. P, I and d values should only be adjusted by professionals.

Proportional Band (P): When P increases, fluctuation of object being controlled decreases. When P decreases, fluctuation of object being controlled increases. When P value is too small, system may become non-converge.

Integration time (I): its purpose is to reduce static error. When I decrease, respond speed is faster but system is less stable. When I increase, respond speed is slower, but system is more stable.

Differentiation time (d): its purpose is to control in advance and compensate delay. Setting d-value too small or too large would decrease system stability, oscillation or even non-converge.

Integration control range (SF): It defines integration range limits. When |SV-PV|<SF, integration control is activated.

Control Period (ot): When ot gets smaller, heating/cooling cycle is drive faster, system respond speed is faster. But when using contact control (Relays), contacts wear out faster. When contact control (Relay) is used, normally set ot=5~30.When non-contact control (SSR) is used, normally set ot=2.

Digital Filtering (Filt): Filt=0, filter disabled; Filt=1, weak filtering effect; Filt=3, strongest filtering effect; Stronger the filtering, more stable the readout, but has more readout display delay.

d) During Normal Operation mode, pressing (^) or (v), the display would show SV. Press (^) or (v) again increase or decrease SV by 1 degree.

By simply press a single button (>) the built-in artificial intelligent is activated to automatically calculate and set parameters (P,I,d,SF,bb,ot) that fit the condition to be controlled.

i. To activate auto-tuning, press and hold (>) until “AT” indicator blinks, which indicates auto-tuning is in progress. When auto-tuning finish, “AT” indicator is off. Now newly calculated PID parameters are remembered and start to be used.

Ii To EXIT during auto-tuning process, press and hold (>) until “AT” indicator turns off. Then previous PID parameters values are resumed.

Polarity of power at terminal 1 and 2 do not matter

Note: By adding the DPST switch, you can switch off the coils and still monitor the cool down temperature in your furnace. The SPST switch turns the controller on only.

User want to control temperature (T) of furnace, 0 ~ 2000 deg F sensor range is required. Furnace is to be maintained at 1880 deg F. System Controller power supply is AC110V. Heating Coils operate on AC220V. . SSR will be used to control the heating element. No alarm output is wanted.
