The CTC Programmable Thermostat measures and stores the amount of time the heating or
air conditioning system operated.
After 500 hours of usage, the word “FILTER” will appear and flash on the display, reminding
you to check or replace your system filter.
NOTE: “FILTER RESET” button works only when “FILTER” is displayed on the display. If
“RESET” button is pressed when “FILTER” is not displayed, the internal counter will not
reset.
