  If the display on your American Standard Thermostat isn't turning on, there might be a few reasons. First, ensure the thermostat is correctly mounted and latched onto the wallplate. Also, check the circuit breaker and reset it if it has tripped. Additionally, see if the fuse is blown and replace it if necessary. Verify that the system switch at the equipment is in the On position. Inspect the wiring between the thermostat and HVAC equipment, replacing any broken wires. If 24 Vac is present, proceed with troubleshooting.

  If you're unable to adjust the temperature settings on your American Standard Thermostat, it might be because you've reached the upper or lower temperature limits. Ensure that your temperature setpoints are within the following ranges: * Heating: 55 to 85°F (13 to 29°C) * Cooling: 65 to 99°F (18 to 37°C).

  If the system on indicator (flame for heat, snowflake for cool) is lit on your American Standard Thermostat, but you're not feeling warm or cool air, it could be because the heating or cooling equipment turns on the fan only when the equipment has reached the setpoint. Wait a minute after seeing the flame or snowflake and then check the registers.
