P,I and d parameters control the accuracy and respond time of the temperature controller. Auto-
tuning is recommended for user who does not familiar PID control theory. P, I and d values
should only be adjusted by professionals.
Note 4
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.
Note 5
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.
Note 6
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.
Note 7
Overshoot suppression coefficient. When overshoot exists, increase SouF. When undershoot
exists, decrease SouF.
Note 8
Control Period (ot): When ot gets smaller, heating/cooling cycle is drived 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=5~15.
When non-contact control (SSR) is used, normally set ot=2.

Note 9
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.
C) To enter temperature and alarm parameter setting mode press (SET), then enter code “0001”,
press (SET) again.

5. Auto-Tuning
By simply press a single button the built-in artificial intelligent is activated to automatically
calculate and set parameters (P, I, D, SouF, ot) that fit the condition to be controlled.

a) How to Start and stop auto-tuning process:
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.
a) ii. To EXIT during auto-tuning process, press and hold (>) until “AT” indicator turns off. Then
previous PID parameters values are resumed. . Note, in order to have auto-tuning to work
properly, a closed-loop system must be established; that is a SSR, heater, thermocouple are
all connected. It may take an hour or up to 24hrs to complete the Auto-tuning. The amount of
time it take is totally depends on how complicated the environment that the controller being
installed.

6. Connection Terminals (back view).
Polarity of power at terminal 1 and 2 do not matter. The “R” is not an external resistor; it is only
available from the Pt-100 thermistor.
Relay J1: #3, #4 = normally closed, #4, #5 = normally open
Relay J2: #13, #14 = normally open

SSR Control
Caution: a heat-sink is required for the SSR
Relay J1 Control
Note: terminal #11 is an opened slot and
there is a diode installed for ambient
temperature referencing. It’s not a missing
screw or defective. For DC type controller,
the power is 12V ~ 32V. The ‘R’ is not a
resistor but it is a feedback resistance from
the PT-100 probe. Do not reverse + / -
when installing a thermocouple. If so, the
increment and decrement reading will be
opposite. For PT100 probe, red wire goes
to #8 while two blues wires go to #9,#10
Pt100 - Red lead terminal 8
Blue leads to terminals 9 and 10

Note: Vref can be AC or DC. It depends on the type of the relay it power
7. Device Application Example
a) User wants to control temperature (T) of a furnace, and 0 ~ 1000 deg Celsius sensor range is
required. Furnace is wanted to be maintained at 800 deg C. Alarm1 will go off if T>850 deg C,
and Alarm2 will go off if T<750 deg C. System power supply is AC110V. Installation opening is
45x45(mm). SSR will be used to control the heating element.
b) Choose JLD612 with a K-type thermocouple.
c) See figure for connection diagram.
d) Parameter setting:
(Inty)=K; (SV)=800 deg C;
(outy)=2; (AH1)=850 deg C;
(Hy)=0.3; (AL1)=848 deg C;
(psd)=0; (AH2)=750 deg C;
(rd)=0; (AL2)=752 deg C;
(CorF)=0;
(auto-tuning is used to set PID parameters)
e) Power up the controller. Keep pressing (>) to activate auto-tuning. When “AT” stop blinking,
new PID parameters are generated and recorded for the system. The controller back to
normal operation mode and the furnace temperature will stay at 800 deg ‘C.
