OPERATION & PROGRAMMING

SELECT SYSTEM MODE (OFF/HEAT/EM-HEAT/COOL/AUTO)

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

CHANGE TEMPERATURE SETTING

• Press OR to adjust the current setting. In AUTO use MODE to switch between the HEAT and COOL setting.

SELECT EVENT-BASED™ AIR CLEANING SETTING

• Press to select:
• ON-24/7: This option will provide the maximum amount of air cleaning available. The air cleaner will be active for 24 hours a day seven days a week.
• 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.
