1. HOW VENTILATION WORKS WITH HAUSMATE


Hausmate measures the air quality in each room by looking at levels of humidity. There is a humidity sensor in each ceiling Sensor Unit, which along with a temperature sensor, is used to measures the Relative Humidity (RH). Optionally, Carbon dioxide and Volatile Organic Compound ( VOC ) sensors can be installed, they will provide a more accurate measure of air quality. 


Hausmate uses its own ventilation system - DCV (Demand Control Ventilation), which automatically turns on the fan in the Zones with poor air quality.

2. HOW TO USE THE VENTILATION APP

The app is controlled through the User Interface (UI). 


To view current ventilation settings in a Zone:

  • Log in to the UI -  click here if you need help to log in to the UI.
  • On the Home page choose the Zone you want
  • At the bottom of the page, click on the icon showing a fan - this will open up the Ventilation control page
  • You can view the current fan's status. If air quality is "Poor", the fan will turn on automatically.
  • BOOST will open the fan or increase the ventilation level, depending on the fan type. (See fan types below).



To change the settings of ventilation: 

  • Log in to the UI -  click here if you need help to log in to the UI.
  • On the Home page, click on the menu button, at the top left hand corner.
  • Select Settings
  • At the top of the page, click on the arrow and select Ventilation


  • The air quality in a room is a value in the range 0 to 1, with 0 being very good air quality and 1 very poor. This is calculated taking into account humidity, CO2 and VOC sensors.
  • The total air quality in a building is the sum of air quality in all ventilated zones of the building. In the example above, the first building has total air quality 0, while the second building has a total of 1.17.
  • There are three different fan types. This field is set when fans are installed and cannot be changed
      • Type 1 has two positions - ON/OFF,
      • Type 2 has three speeds - ON/LOW/HIGH 
      • Type 3 has speeds ranging from 0 (OFF) to 100 (Maximum Speed).
  • The BOOST button will open the fan (for type 1) and increase the ventilation level (for type 2 and type 3).
  • The RECALIBRATE button will find the fan's home position, to ensure that the ON / OFF status on the screen corresponds to the real status of the fan. The calibration is done when the system is installed and should be repeated only if you notice a disagreement between the UI and real status. 
  • When you click on EDIT, a list a value will appear. These are default values for calculating the air quality and should not be changed! ( G - gain, O - offset, so for example VOCG stands gain for VOC value).
  • The Fan Level - is the value for air quality above which the fan will be turned on.



  • The Global Settings gives the times, in seconds, for the valve opening time and standard fan on-time. The valve opening time should only be changed in case of recalibration.
