siemens rdj10rf?
My wall thermostat unit shows a continuous test page, ie 888 etc, even though it is set to Auto and Run. I've replaced the batteries and tried all the other advice to get the two units to talk to each other, I'm beginning to assume that the wall unit of the two (the other being the RCR10/433 receiver) is broken, correct or incorrect?
