Everything Drolet Tundra - Heatmax...

[TDD11]

I called Honeywell they said the supply voltage range is 20v to 30v. I don't think it is a voltage issue. I may measure amp draw this weekend, although the damper seems to open and close freely.

Perhaps I just got a bad one and I am reading into this too much.

I've been pretty tempted to retrofit a Totaline controller onto my old Silver Dollar Saver stove in my workshop.

I have a Heatmax build number 676 and I've been think about adding something that actually controls the burning temp instead of the dumb thermostat for a while now. Then I started researching and found you guys !

I really like the idea of the PID controller opening / closing the damper based on flue temperature. But if I buy a controller, I would also like to be able to control fan speed.

I wonder what king of controller could do that ?

Or maybe plug the fan in high speed then wire in a rheostat to slow it down ?

I'd recommend an Auber 2342 with an integrated relay. They provide support, and they have clear directions. If you aren't familiar with PID controllers there are some good YouTube videos on how to get one setup.

The fan speed controller has been discussed thoroughly in this thread.
