For extra comfort and convenience you can combine the DTM04 tank monitor with Dometic’s automatic tankdischarge control. This easy-to-use control system allows you to turn on the discharge pump anytime.
When the keyed control switch is set to the automatic mode the discharge pump is activated as soon as the holding tank reaches mid level. In the manual mode you can turn on the discharge pump directly – provided you are sailing in unrestricted waters.
Once you enter a “No-Discharge Zone” the tank discharge control must be switched to the OFF position to prevent accidental discharge.
