I have a Ranco single controller. It has a couple heaters plugged into it in case my controller has a fit, and it's set 1 degree lower than the controller.
I've had it for 3 years now and it's still accurate.
Only thing I don't like about it is it's lack of decimal points so I can match it to my controller.
Having everything on one controller is so much easier to program. Alarms can be set amongst components etc. But then you have 1 piece to fail, so you have to set rules for on/off if the controller loses contact with the power bars.
