• Press MODE  to select:
• AUTO: The thermostat automatically selects heating or cooling depending on the indoor temperature.
• OFF: Heating and cooling systems are off.
• HEAT: The thermostat controls only the heating system.
• COOL: The thermostat controls only the cooling system.
• EM-HEAT: Thermostat controls emergency/auxiliary heat. The heat pump will not operate. (Only for heat pumps with auxiliary heat.)

• AUTO: Air cleaning will not occur for the sole purpose of air cleaning, but will occur during fan operation for heating and cooling.
• CIRC-30/HR: The air cleaner will run a minimum of 30 minutes every hour. The air cleaner will monitor the amount of time your heating and cooling system runs; if 30 minutes is not reached the air cleaner will automatically turn on. This will maximize the amount of air cleaning while minimizing energy consumption.
• EVENT-3HR: When selected, the air cleaner will run continuously and then return to the most recent mode of AUTO, CIRC-30/HR, or ON-24/7. Use this option when the air needs cleaning; an example would be after vacuuming.
• ALLERGY-24HR: When seasonal allergies spike and outside air quality is at its worst, choose this option. Your air cleaner will run continuously for 24 hours and then return to the most recent mode of AUTO,
  CIRC-30/HR, or ON-24/7.
