### To switch a Robert Shaw RS 3110 from farenheit to celcius?

First open the unit, as if to remove it from the wall by pressing the release button at the bottom of the unit and tilting it upwards. You should see a bank of 4 dip switches. On my unit these were red. Switch 4 selects temperature units. The circuit board is labelled Fahrenheit. Change this then close your unit and press the reset button.

### My Robertshaw 9600 displays 99 degrees and because it is satisfied, is not calling for heat. The temp is actually in the lo 60's and falling. I've tried battery replacement, but nothing changed. Other...

Hmm. I don't think it posted the first time around. So I'll try again.

There is a temperature sensing diode on the back side of this thermostat's circuit board. This diode may have failed or become disconnected.

I'd lean towards its having become disconnected, as I've been inside an example of this Robertshaw (originally Maple/Chase) 9600 thermostat and noticed that the soldering on this part was of poor quality. So if you have a soldering iron, and know how to use it, you could probably fix it.

I have a web page (just the facts, no ads, malware or fluff) that talks of some other common problems with this thermostat and how to fix them:
