What to do if my Niagara ECO IQ N9195 Thermostat is not producing heat?

To troubleshoot a Niagara Thermostat that's not heating, first, ensure the system switch is set to HEAT and the set point is higher than the room temperature. If the flame icon is blinking, wait for the 5-minute compressor lock-out to expire. Also, verify the thermostat wiring and connections, and check the pilot light or HSI system on your furnace.
