Heater digital controller, FH 270

Replaced controller

Great to work with took a few tries to get me the right thing but very responsive great service!

The new controller I received still does not perform the way the manual says it is supposed to function. The data that shows the temperature coming in and then going out (after heating), are reversed. I can only assume the heat pump is even working. It is disconcerting to be unsure the FH 270 that I paid quite a lot of money for, may not be functioning properly.
