Tstat display issues

Hi All,
I did program my tstat and is working fine, but I want to know how to change the signs on the display to match with my thermostat state.

  1. the system and fan is in auto. The unit is cooling at this moment, but thermostat shows the fire sign.
  2. Is it possible to get to the schedule and change it directly from the thermostat?
  3. I have some variables like night setpoints for heat and cool. How I can show it to the customer so they are able to change them?

Just to clarify. I am looking to show the right icons based on unit status.
