It was amazing.

Aprilaire Thermostat 8400 Series Dec 14, 2016

Its difficult to believe I am the first to review this product. However this thermostat is difficult to program and seams to defy reason, when in heat mode and should be using the compressor unit outside to produce heat, it instead will be making expensive heat with AUX electric heat. I will probably dump this thing and get one I can understand how to use effectively.

Too Early To Tell Sep 07, 2016

Hooked up the heater in late June, so no way to tell how it will work when the cold weather arrives. Hook up was easy, except the schematic didn't really tell which of the possible 5-6 spots the two line thermostat was to be hooked. Blew a fuse the first time I turned it on, but the second placing of the thermostat lines worked.

Couldn't be happier with my new water heater. I used PVC for venting and had a bit of water and gas line plumbing to do, but installation was a piece of cake. Delivery was quick, the box was a little rough, but the water heater was in perfect condition.
