How do I set up an air filter replacement reminder on the thermostat?
In the Installer Setup (ISU), navigate to ISU 702 to set the number of air filters (0–2), then use ISU 711 and 712 to configure the replacement reminder intervals for each filter. Reminder options range from 10 run-time days up to 15 calendar months, or can be turned off entirely. Setting to '0' turns the reminder off. (Page 10)
