If you turned the ring and the pointer moved, then you are using the thermostat correctly. Turn the thermostat up above room temperature (the temp on the bottom of the thermostat) Make sure all your switches are on, and that the fuse or circuit breaker is also on. If you still do not have heat after verifing all these things, then it is most likely a problem with the heating appliance.
Also, if it is a heating and cooling thermostat, make sure your lever is in the heating mode. Hope this helps
