This happens to my rwb29 from time to time. You can try switching off the power to the controller for a couple of minutes with CH thermostat and CH programs set off. Or you can press the little reset button to the bottom right of the LCD screen. After 1 or 2 attempts these steps usually restore the independent control on my unit.
