Hey everybody SPyderRobotics answered me:
EZ2 and Herpstat 2 will do identical regulation. Same code under the hood. The big differences are:
Herpstat 2 has:
Night drop with built in clock if you need to drop temps at night.
LCD allows setting exact tenths of a degree and you can see what it is actually getting to. The EZ2 does set in tenths under the hood and the LED indicator gives you a overall idea of temps.
H2 can show you your high and low temps. You can see how much power its applying.
H2 has the safety relay that can be set to turn off all outputs if a high or low alarm is breached.
So there are alot of features the H2 has over the EZ2 but not everyone needs those and as far as temperature control the EZ series is going to do the same job so its a great value. Plus some people just don't want to get involved in changing options in a menu. They want the ease of setting a knob and being done.
