Summary:PROBLEM TO BE SOLVED: To provide a control device which is suitable to control over an operation mode in which motors of a plurality of motor-driven selector valves for flow passage switching are driven simultaneously for a hot water supply bath device equipped with the plurality of selector valves.SOLUTION: The control device includes a main control board 50 and a child board 53. The main control board 50 includes a main control circuit which controls device operations and a power supply circuit 51. The child board 53 includes a motor control driving circuit 58. The motor control driving circuit 58 alternately drives a motor M1 for a first selector valve and a motor M2 for a second selector valve one by one at different timings in a motor simultaneous operation mode of the motor M1 and the motor M2 by applying a power supply voltage from the power supply circuit 51 of the main control board 50 directly or through a remote control device.
