I had no way of getting my room as warm as I needed it to be (excluding Summer time). I had used two UTHs and controlled them "separately" using the Herpstat 2. Worked like a charm. Glad to say I no longer have to use two UTHs and it's nice for two different enclosures.
I should also add the Herpstat 2 has two inputs for two separate sources and they each can be set to different temps and other options and is why I recommend it for you.
