PURPOSE: A control device for a hot-water control valve is provided to improve deceleration ratio and durability and reduce noise and manufacturing cost although a few number of gears are used. CONSTITUTION: A control device(100) for a hot-water control valve comprises a housing(110), a mounting plate, a drive shaft, a drive, a handle wheel(140), a final gear, a drive unit, a power transmission unit, a clutch unit, a circuit unit, and an on/off switch unit(200). The housing is fixed on the hot-water control valve. The drive shaft is vertically installed on the mounting plate. The drive controls the opening degree of the hot-water control valve. The handle wheel is fixed on the upper end of the drive shaft. The final gear engages with the drive shaft. The drive unit rotates the drive shaft. The power transmission unit delivers the power of the drive unit to the final gear. The clutch unit selectively releases the engagement of the drive shaft and the final gear. The circuit unit controls the opening degree of the hot-water control valve.
