LAMP MARKS
HEAT ON : WHEN OUTPUT IS HIGH, IT IS MARKED “ON” (RED LAMP)
SET : ONLY SETTING IT IS ON (GREEN LAMP)
POWER : FLICKER AT THE STATE THAT THE POWER OF CONTROLLER IS “ON” (RED LAMP)
BASIC MOTIONS
POWER IS ON/OF F WITH POWER KEY: DURING OFF, NO KEY WORKS.
UPON PUSHING ∨ OR ∧ BUTTON, THE SET LED IS ON AND THE SET VALUE IS DISPLAYED. NO CHANGE OF A KEY FOR 3SEC AFTER CHANGE OF SET TEMP., THE SET LED IS OFF AND
THE PRESENT TEMP. IS DISPLAYED.
FUNCTIONS
tn, THE START OF FUNCTION, IS DISPLAYED AFTER PUSHING ∨ AND ∧ KEY FOR 3 SEC SIMULTANEOUSLY .
IN THE DISPLAY OF tn, BY PUSHING ∧ KEY, MENU IS DISPLAYED IN THE ORDER OF En - in – St . IF SELECTING A MENU, PUSH ∨ AND ∧ KEY
SIMULTANEOUSLY.
Sn METHOD = THIS WORKS BY SENSOR; SET THE TARGET TEMP FOLLOWING TO <TABLE 1>.
             FOR SETTING, AFTER SETTING THE TARGET TEMP, PUSH ∨ AND ∧ KEY SIMULTANEOUSLY. IN THE FINAL STEP, AU FLICKERS FOR 3 TIMES AND THE SET VALUE IS SAVED.
AFTER COMPLETING THE SETTING, SET THE TEMP WITH ∨ , ∧ KEY; IF NO CHANGE IN KEY, THE PRESENT TEMP IS DISPLAYED AFTER 3SEC. AND RUN.

TIMER FUNCTION
BY PUSHING ∨ AND ∧ KEY FOR 3 SEC SIMULTANEOUSLY, THE INITIAL tn IS DISPLAYED. PUSH ∧ KEY ONE MORE, Sn IS DISPLAYED. AS Sn IS THE METHOD BY SENSOR, Sn
IS SAME TO THE PRESENT METHOD. IF PUSH ∧ KEY ONE MORE, tl IS DISPLAYED; AT THIS TIME BY PUSHING ∨ AND ∧ KEY SIMULTANEOUSLY , THE PRESENT CYCLE VALUE IS
DISPLAYED. SET THE CYCLE. WITH ∨ AND ∧ KEYS,. IF PUSHING ∨ AND ∧ KEY SIMULTANEOUSLY ONE MORE, AU FLICKERS AND THE CYCLE VALUE IS SAVED AND THE
PRESENT SET INTENSITY IS DISPLAYED.
HOW TO SET BY SERVICEMAN = PUSH ∨ AND ∧ KEY SIMULTANEOUSLY – tn DISPLAYS ON THE WINDOW – SELECT tl BY PUSHING FOR 2 TIMES – PUSH ∨ AND ∧ KEY

7. TROUBLESHOOTING ERROR MESSAGE SNAPPING TEMP SENSING SENSOR
BASICALLY THE CONTROLLER IS ON/OFF ACCORDING TO THE INDOOR TEMP SENSING SENSOR. IN CASE INDOOR SENSING TEMP SENSOR IS SNAPPED,
IT IS CONTROLLED AND WORKS AT THE TEMP VALUE OF Field SENSOR AUTOMATICALLY. IF THERE IS NO Field SENSOR OR THE Field SENOR IS SNAPPED,
‘EO’ ERROR IS DISPLAYED AND THE OUTPUT IS OFF PROMPTLY.
(SUCH ERROR IS OCCURRED DUE TO THE FAILURE OF SENSOR SENSING UNIT; SHORT OF SENSOR EXTENSION LINE; ELECTRIC LEAKAGE FROM THE SPOT ATTACHING SENSOR . INSPECTION IS
NECESSARY AND IN CASE OF CLEAR, RETURN AUTOMATICALLY.)
SHORT CIRCUIT OF TEMP SENSING SENSOR
BASICALLY THE CONTROLLER IS ON/OF F ACCORDING TO THE INDOOR TEMP SENSING SENSOR..
IF THE INDOOR TEMP SENSING SENSOR IS SHORT, “ES” ERROR IS DISPLAYED AND POWER IS OFF SHIRT CIRCUIT SHIRT CIRCUIT OF
OF INDOOR SENSOR OF Field SENSOR
IF Field TEMP SENSING SENSOR IS SHORT, “FS” ERROR IS DISPLAYED AND POWER IS OFF.
OVERHEATING ERROR
THIS OCCURS WHEN Field SENSOR SENSING TEMP IS HIGHER THAN THAT OF OVERHEATING SET TEMP. ..
“OH” IS DISPLAYED AND THE OUTPUT IS OFF PROMPTLY.
WITH MANUAL RETURN METHOD, POWER OFF-ON IN THE STATE THAT OVERHEATING ERROR IS CLEAR.
(CHECK THE STATE OF OVERHEATING SENSOR; CONTROLLER RELAY MOTION; SNAPPING OF Field TEMP SENSOR; OR SET TEMP VALUE)
