VE-100 vs VE-200 Question

[stealthclown]

Hi i am looking at the VE-100 thermostat and the VE-200 and the only difference it says is the ve-200 has proportional and its says under that "yes-pulse" what does that mean?

Thank you, Stealthclown

[stealthclown]

So i figured the differences i ordered the ve-200

Good choice ... You want the proportional feature

[stealthclown]

Yeaa i read up on it and i didnt want slop lol

Well with VE there is pulse proportional and dimming. With Herpstats, they all come both pulse proportional and dimming. I prefer dimming. Pulse proportional is basically like flicking a light on/off hundreds of times a second. Dimming is actually limiting the power the item. So basically you don't want pulse proportional for something like heat lamps as it can cause them to flicker or strobe. So if you are set on a VE, get the VE 200D which is their only dimming model. kind of surprised their dual stat model isn't dimming as well. And like I said, for Herpstats, they have both so you can pick which mode you want to use. I personally use dimming mode for my RHP on my Herpstat 1.

Thanks for explaining the difference Sauzo. I plan on getting a Herpstat and I probably would not have understood that so simply from their directions.

I would add that if I was looking at a new stat I would be certain to get a model with a safety relay. The trial controller that is used in (all?) most proportional stats has a tendency to fail on. Meaning it no longer controls the temperature and runs full power all the time. The relay prevents this and failures result in no power. It is like having a fail safe set up built in.

If you don't have this feature I would recommend a fail safe unit be added to the stat something like a johnson, ranch, VE100, even a hydrofarm would be well suited to this use.
