  The Pump Model Name Aquapro AP1050 Waterfeature/Pond Pump Model Number 02AS003B Material Durable Plastic Wattage 18 Maximum Flow (litres per hour) 1050 Voltage 240 Cord Length (m) 10 The baffles The matrix Spray pattern

  30°C plus Autumn day here a good test fro the cooler in anger   70 Liter bin a tank and a 750LPH bilge pump

  Smart control: - reduces power costs of air handling units - adjusts ventilation to your everyday needs - provides a wide range of control options It has been estimated that smart control allows to half the average cost of electricity for ventilation. Air Quality Hubiat Prototype 1 of control system

Encouraging results  from logged data. Very stable internal environment in the house.  Energy use for Greenway Room temperatures All rooms are very similar so the heat is being distributed evenly it seems.  Room humidity Very important as we are still having col mornings the humidity is also very well distributed.  

Live data feed from Hubitat Cloud   

 We get around a 1C boost to the fresh air from loft heat exchange with the duct. The loft is consistently between 4 and 15 C hotter than the outside air and even at night boosts heat in the fresh air duct to the living room. An unanticipated benifit

  Drop on exiting air 2.9C Heating of incoming air 2.5C So 86% of the heat recovered

  We have a data logger running every 6 minutes we save stripes of data from Hubitat to disk using a call to my Tiny Webserver in Rule Machine  See Web Server Source C#

 

  Progress over the weekend with the ERV DAS The 999's are me testing the sensor disconnected response. I have a Pitot tube left over from an RC plane I think I might put it in the inlet air stream Pin assignment in the Arduino sketch DHT dht[ 4 ] = {DHT( 4 , DHTTYPE),DHT( 0 , DHTTYPE),DHT( 2 , DHTTYPE),DHT( 14 , DHTTYPE)}; There are 4 DHT22's inside heat exchanger lid, shown below.
