The batteries in my Digistat RFI thermostat have died and I don't know how to change them. It appears to be a sealed unit but there has to be a way.
I've take the unit off the wall but how do I get the back off the unit to get to the batteries?
Can anyone help?

Turn the unit face down, you will see two plastic 'loop' like projections on the rear. Put your finger under one of these and lightly lift it, at the same time with your other fingers pull the battery drawer out from the bottom of the unit. The batteries will then be accessible to change as they slide out at the bottom. Repeat for the other drawer. Hey presto!
