An important thermostat question

[Argentra]

I have a small dilema that I know you guys can help with.

I have had my new tank going well since Thursday, with a UTH and CHE on a rheostat, keeping very stable temps of warm: 90-92, ambient: 84-85, cool: 81-83. I just got my new reptitemp 500R thermostat delivered today.

The question is: should I hook up the UTH and CHE (which mainly control the warm side) to the new thermostat now, messing with the temps until the right level is reached, or should I wait a while until the basic temps here in Denver start dropping and thus my tank temps? I just don't want to mess up what seems to be a stable environment.

If you had a setup before that was running well...I would say that if it ain't broke, don't fix it.

I especially wouldn't change anything in favor of that Zoo-Med thermostat. I used one of those once upon a time, it failed, and had I not been home to see where the temp spiked to, I could have lost most of my collection. Others on here have had similar experiences. I personally don't feel they are worth the cost of the plastic that they are made of.

But to answer your question, I'd control the UTH with the thermostat and use the rheostat on the CHE. Doesn't matter what time of year, but you'll have to tweak the settings on both as your room temperature fluctuates.
