Replacement Install
Purchased to replace Tank Watch III unit. The unit display is not the same size as the old one, so assume you will need to fashion a new mounting plate. Also, the part did not come with the 4-conductor cable (tank probes to the display), nor was it readily available. Making this up took hours. Otherwise straightforward install.

Questions
I have 3 tanks I want to monitor, 2 fresh water and the wastewater tank. The Dometic website says the DTM04 is for monitoring the waste tank and the DTM08 is for waste and fresh water and DTM12 is for waste, fresh water and gray water. Please clarify
The DTM12 would monitor all three tanks off of a single monitor. The DTM04 only monitors the one tank (waste), the DTM08 can monitor 2 tanks simultaneously (waste and fresh water). Please feel free to reach out to us at [email protected] if you have further questions or need specific guidance.

When is tank full? When only the full red light is on? I worry when yellow, gold and red are all on.
Haven’t got past yellow yet. But the only wat to correlate the lights is to shine a flashlight on the tank to see the level. I’ll be checking all the way to red
