Preferred Thermostat?

[AlexisFitzy]

I feel very very stupid asking this question but if a thermostat is dual zone, can it control two different heaters (in two cages) off of it? Or does that mean it monitors both the warm side and the cool side and makes adjustments accordingly?
Specifically the Herpstat2 or the ve-300x2.

We are upgrading caging set ups for our two guys and want to make sure we do it right.

A Herpstat 2 or VE-300x2 controls two separate heating elements individually. I have a Herpstat 2 that's regulating two racks right now. These are 2 thermostats in one package the Herpstat 4 is the same way. It can control 4 individual heating elements. Hope this is helpful
