Nice Size
I bought 3 units to regulate small heaters. Each unit has a different dead band range which is my only complaint. They work and I will buy more when needed.

Can this unit operate with a remote sensor? What sensor would be required? If not, what is available that does operate with a remote sensor?
The KT011 series and all like models have internal sensors and no options for remote ones. You would need to call the Temperature group to discuss alternative approaches or email them at temp@omega.com.
