Aprilaire 8476 Programmable Universal Thermostat

Are you looking for an attractive thermostat that is packed with features but low on price?  You have found it!  The new Aprilaire 8400 series thermostats have all the features you are looking for at a value price!

Model 8476 is universal and will control  - Standard Systems gas / oil / electric.  Single Stage/Heat Pump/Multi-Stage, Millivolt Systems.  The 8476 offers "Event-Based" fan control which can run the HVAC fan in 5 different modes.

Feature Description:

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.
