There are many smart programmable thermostats that allow for automatic operation of

the air-handler fan unit when there is no demand for heating or air-conditioning. It is

important that the ZAND-AIR PCOC3™ is operating from ten (10) to thirty (30)

minutes per hour twenty four (24) hours per day to remove toxic materials from the

indoor environment.  

The length of operation depends on the location of the facility in relation to point source

of pollution such as refineries, processing plants, automobile traffic and areas that

produce high levels of pollen or other pollutants. Individuals that are sensitive to mold

spores, dust mites, chemicals or have respiratory problems such as asthma,

emphysema, and chronic allergies should extended the run time to (20) minutes per hour

24 hours.

 Note: In the event, the existing thermostat does not have the capability to operate the

air- handler fan unit independently of a demand for heating or air conditioning, it is highly

recommended that an AirCycler be installed.

 This device is simply wired in parallel with the existing thermostat wire and can be

programmed to turn on the air handler fan unit for any desired interval. A memory tracks the time the fan unit operates every hour and only cycles the fan unit that hour if normal

requirements for heating and air-conditioning have not cycled the fan unit long enough to

meet air purification requirements. 

The AirCycler can be purchased from any HVAC wholesaler, or from

sales@zandair.com.
