① How to wire sensor.
▶ Connect the wire as shown in the
picture in right. Wrong wiring shall
cause an error.

in display.
②How to extend sensor wire.
▶In case to extend RTDsensor and
K, T sensor, refer to caution 11 and
12 in Page 1.
▶Extension of IC, humidity and
themistor sensor is available within 100m.
▶ Use the wire which has a shield
In order to prevent any noise
input, when you want to extend cable
of sensor.
③ How to compensate the variation.
(when current indicator of
temperature is wrong.)
▶ A long sensor wire and a old
sensor may cause a variation in
temperature. Compensation
feature(rSt) could be used.
▶ At current temperature, press set
key for 3~ seconds.
▶ Release setkey when dIF or P is displayed. Setkey several times to
move to rSt.
▶ Up(up),Down(dn)key to input the compensation. Set key for 3~
seconds will memorize and amended value will be displayed.

StL

Down limit of temperature to 40 degree.
▶ set key for3~ seconds will memorize the value as effective from that
time on. ※ Since then, reset if temperature is available in the range of
50℃~40℃only.
▶ Main output could be reset by using the bellows. (set key will skip to
next step at every pressing.)
* Example : DIF and TYP input value
① TYP = at C(cooler(in reverse direction)) state
ex) assuming of preset temperature 10.0℃, DIF = 2.0,
Relay ON : 12.1℃, Relay OFF : 10.0℃
② TYP = at H(heater(in right direction)) state
ex) assuming of preset temperature 10.0℃, DIF = 2.0,
Relay ON : 7.9℃, Relay OFF : 10℃
* assuming dLt=10, Relay will be ON in 10 seconds.
* assuming tyP = C(cooler), will be used for lowing temperature.
* assuming tyP = H(heater), will be used for increasing temp.
