BAH-1000 Failed on me!

Hi,

I think your misunderstanding the dimmer concept.

It does not go between the thermostat and the wall - it goes between the thermostat and the heater.

The thermostat gets full line voltage at all times and would not be screwed up in any way by the above setup.

The idea is that if the thermostat jams full on the damage is limited by the throttling of the dimmer - meaning that while the tank will get over temp it should only be by a few degrees not 10 or 20.

This is correct, the dimmer switch doesn't affect the input into the thermostat, it only throttles the voltage output to the heat source, so the heater will not go beyond a certain threshold even if the thermostat is stuck on.

Yeah, I guess I should have been more clear about where I had the dimmer hooked up. I had it hooked up how Crawdad/Dr. Del described. The snake appears to be fine so fortunately no damage done. Just a nervous snake owner.

Ah that sucks then =(

I use a ranco for some months now. No problem at all. And I actualy enjoyed wiring it. But I like that kinda stuff =)

I'm using a Johnson and it works great. I've heard a lot of bad things about the BAH-1000, but I use this one as well:

I got my Johnson from Reptile Basics:
