▣ Cautions for safe service

When moving the product, take hold of the body at all times.

When disassembling or assembling the product, lock the water insert valve.

When exchanging or repairing electric parts, plug the power out before starting to exchange or repair.

When exchanging electric parts, use authentic/rated parts. (ex- fuse capacity, etc.)

Check if moist penetrated to electric parts.

Check assembly status of parts after repair.(ex- cable tie, harness arrangement, etc.)

♠ ♠

Ground connect when ground connection is deemed necessary.

Avoid using many power plugs at the same time for easily heated products or highly power consuming products.

Avoid risk of exposing wires from harness/wire/joint when repairing.

Remove dust or foreign substance completely from wire junction/housing part/contact point when repairing.

Do not put back a different main pcb connector when repairing.

Take extra care in handling and storage as IC and semiconductor chip in PCB can be damaged by static electricity. Check product usage environment and change the location of use when installation status is unstable. (ex- Bathroom in master room→Bathroom in living room)

  • Operated when pressing "Bidet switch" during cleaning or blowing.
  • Operation

① Rotate VALVE MOTOR in nozzle cleaning, rotation/nozzle motor in stop position ② Nozzle cleaning for 1 second by operating pump ③ Move to bidet position by operating nozzle motor ④ Start bidet functioning by operating pump ⑤ Move to stop position by operating move/nozzle motor ⑥ Nozzle cleaning for 1 second ⑦ Stop

♤ 2) Cleaning

  • Operated by "Cleaning switch" control while the seat is sensed as taken
  • Operated when pressing "Cleaning switch" during cleaning or blowing.
  • Operation

① Rotate VALVE MOTOR in nozzle cleaning, rotation/nozzle motor in stop position ② Nozzle cleaning for 1 second by operating pump ③ Move to bidet position by operating nozzle motor ④ Start bidet functioning by operating pump ⑤ Move to stop position by operating move/nozzle motor ⑥ Nozzle cleaning for 1 second ⑦ Stop

♤ 3) Blower function

  • Operated by "Dry switch" control while the seat is sensed as taken
  • Operated when pressing "Dry switch" during bidet or cleaning operation.
  • Automatic operation of blower function after 2 minutes since cleaning or bidet operation
  • Operation

① Drying fan operation ② Drying heater operation ③ Stop

  • Stops when stop, bidet, cleaning switch input

♤ 4) Deodorization and human body sensor

  • A function that supersedes all other functions. Identifies whether someone is seating on the toilet seat and delivers the result to MICOM in electric signal.
  • Operation

① When human is detected, motor fan starts to operate and wind passes through granular basic activated carbon catalyst. ② When toilet seat cannot detect human body, deodorization function stops.

♤ 5) BACK-UP function

  • Information on hydraulic pressure, hot water, blower, seat temperature does not change and maintains the final setting while seat switch is ON.

♤ 6) Leakage prevention

OP AMP IC operates AC drive relay the electric leakage value recognized by ZCT device to turn OFF Ac power, when electric leakage over 15mA occurs in AC driver. At this time, when leakage preventer is operating, all functions are suspended.

♤ 7) Power saving function

  • When automatic power saving function is selected, power consumption of hot water heater and seat heater is minimized.
  • Operation

① When pressing power saving switch while human body is not detected, power saving LED is lighted and power saving function starts, ② Maintains temperature of hot water in hot water heater in 30℃. ③ Maintains temperature of toilet seat heater in 30℃. ④ Power saving LED is lighted during power saving operation. ⑤ Stop When the toilet seat detects human body, power saving function is cancelled. When human body is not detected, power saving function returns to power saving MODE.

♤ 8) Power ON/OFF function

  • When bidet is not used for a long period, press power switch to turn OFF power.

At this time, Main power is OFF and returns to ON when pressing power switch again. When turn ON power, valve and nozzle motor retrieve initial positions.

♤ 9) Nozzle cleaning function

  • A function of cleaning nozzle in case of long-term use.
  • Starts when pressing nozzle cleaning switch, regardless of stop position or body detection
  • Operation

① Moves valve motor to nozzle cleaning position, nozzle motor to stop position ② Operate Pump motor to clean nozzle (1 second) ③ Drive NOZZLE MOTOR (Exposed to the extent of maximum length) ④ NOZZLE cleaning (manual cleaning by user) ⑤ Moves to nozzle cleaning position/nozzle motor stop position when pressing nozzle cleaning key or 2 or more minutes have elapsed ⑥ Operate pump motor to clean nozzle (1 second)

♤ 10) Self-diagnosis function

  • This function does not require additional switch input.

MICOM puts out corresponding LED and suspends the function hindered part in part or in whole, when abnormal condition is found. The self-diagnosis function of this controller focuses on temperature control part. It automatically returns to normal position when the problem is settled. Function Indication
