Dometic 2 zone t'stat wont switch o zone 2
My Silverback has two AC units; 15k Briskair in rear and a Penguin 13.5k in bedroom. The Briscair is zone 1, and the Penguin is zone 2. When i set up, the t'stat had an E1 error code, so I initialized the system per the manual. Now, it will not switch to zone 2 at all. So that means We only have one AC unit working. Its 97 in the shade wih 95% humidity. Would really like to have both AC's working.
Does anyone know how to program the t'stat so that it will see both zones?
