The modd (mains operated drain doser) and bodd *(battery operated drain doser) are automatic dosing systems that provide the timed delivery of a single product. They are controlled by a real-time clock and offer up to eight programmable timing entries. Programming is achieved using an excternal keypad with security access protection and is viewed on an alphanumeric display.

The bodd incorporates a compensation facility that will increase the pump run time uin relation to the reduction in battery power in order to maintain a consistent dose. A battery life indicator is also available on the display.
