Hi
Does anyone know why a Honeywell ST9100C Programmer is continually flashing. I have looked at the troubleshooter details but it does not give an answer.

Is it time to get another??

Thanks

Paul
 
It's faulty alright, if it's less than 18 months old it'll still be under warranty. I take it you can't control anything with it. There not as good as they used to be.
 
Can someone advise on which thermostatic programmer could I directly replace my excisting Honeywell cm51. It's connected to a combi. I know the Honeywell cm61 and cm67 is a striaght swap but is there another models out there that is just as good as Honeywell?
Thank you
