Make sure both the thermostat and the remote are on the same channel. Also some channels work better than others depending on your situation. If you do not have a C wire connected to the thermostat the remote will not function. If you do have a C wire connected it may not be working correctly. To test to see if the C wire is working, remove the batteries from the thermostat and see if it still functions. If not the C wire is not working.
