You need to use a T822 (heat only) or T834 (heat/cool). Fortunately neither these nor the T827 is very expensive.

Just saw one
For the first time the other day...I was asked to install it on an OWB setup, but as I pointed out to the H.O., the T827K is designed and rated for 12v. D.C. systems. Can it be used on a 24v. A.C. system or not?0
