Air Conditioner Energy Saver

this is a pir motion sensor switch having dual output. it can handle the  load  of  an  air  conditioner  of  capacity  up  to  2  tons  without  a contactor and a lighting load of 200 watts simultaneously and inde-pendently in six different user selectable operating modes. this is an ideal product for saving energy while using air conditioners.
the  device  detects  movement  based  occupancy  and  keep  the connected  appliance  (like  air  conditioner,  lights,  fan  etc)  on.  it turns  off  the  connected  load  when  its  detection  area  is  vacant. the  lux level  setting  equipped  with  the device helps in  turning on the  lights  only  when  day  light  /  ambient  lux  level  falls  below  a  de-sired selectable level.
in  offices  electricity  consumption  due  to  air  conditioners  plays  a major  role.  a  2  ton  ac  consumes  3  units  in  one  hour.  considering electricity  charges  as  rs  10  per  unit,    and  a  saving  of  2  hours  with the device, a monthly saving of rs 1800.00 is achieved, which results a pay back of 3 months approximately
features :

• dual output.
• motion based on / off for air conditioner
• motion & day light based on / off for lighting load
• over load protection
• surge protection
• huge energy saving
• very short payback period
• 24 months warranty.  
• six different operating modes

auto mode (default mode):
output’s will be switched on based on occupancy, and remains on  depending  on  the  off-delay  set  by  user  after  detecting  last motion.
manual mode :
auto mode can be overridden to various operating modes by using override   switch,   performing   number of switching   operations prescribed in user  manual  within  a  span of  six  seconds.  sensor  will then switch on-off lamp once as an indication towards successful change  in  operating  mode.  if  the  unit  is  working  in  manual  mode and  is  not  overridden  to  auto  mode,  it  will  return  to  auto mode automatically after 2 hours
