TAB 400 2021 Outside Pump Switches

Giota

There are 2 outside pump switches for the TAB 400 2021. One above white, one below red. I assume you have to have the white one turned on for the pump switch to work inside. Yes? What is the red one for?

Paul gives a nice review.  Think of the top,switch as a three-way light switch, allowing you to turn the pump off and on from outside or inside.

The Nautilus System, which is basically a manifold valve system, is covered quite well in its manual, which describes the function of each switch and valve in detail.  The two switches are also labeled on the panel next to the switch.

Thank you very much.

@Giota Good!  Now when you figure it all out, come back and teach us😁

The top white switch is for the 12v pump which works independent from the switch inside the trailer.  It lets you siphon water into the tank or use the exterior shower without having to go inside to turn on the pump.  The lower switch is not functioning on the T@b 400 but is there to turn on tank heaters if the trailer is so equipped.

Yes, this is correct. The lower switch is not connected to anything.
And the pump switch simply turns the water pump on or off, and is connected in a 3-way fashion to the switch inside the camper by the front door.
It's function is no different than the switch by the front door...it turns the pump on or off, that's it.
You can turn the pump on at the outside switch, and off at the inside switch, and vice versa.
The outdoor pump switch is there for convenience.

In regards to the red switch, is it possible to install tank heaters on the 2021 Tab400 and route them to this switch? Assuming it already has power to the switch?

thanks

You could certainly wire the switch for that purpose, but there are no connections to it from the factory...it is just a blank switch.
