My RF546 thermostat doesn't appear to work. I've tried

Customer Question

My RF546 thermostat doesn't appear to work. I've tried replacing the batteries- a small leak had occurred. Is it supposed to show anything when I put new batteries in? Anything on the screen?

The screen is blank and the signal light is flashing on my Worcester boiler. I have tried going into LRN mode and nothing happens.

Im sorry to say you should get some indication of power when you replace the batteries, Try cleaning the contacts for the battery, if this doesn't work then it looks like a new one is in order.
