Seems not to be working..
there are two lights and two buttons - test and install.
I put fresh batteries in the sender and tried to get it to come on, but no joy..
can anyone remember the sequence to test and register the thing?
When I found it the bottom red light was on... pressing the test button got the heating working..I tried test+install together and got a red blinking light that then stopped after 3 secs.
Now there are no light on although the sender is calling for heat..any ideas?
Suspect the thunderstorms have done something. I did power cycle it too.
