Carbon Dioxide (CO2) Monitor / Controller

£225.00
Our CO2 monitor and controller provides valuable information on air quality and gives an indication of when ventilation is required.  Ideal for assessing ventilation adequacy in Passive Haus buildings and other air tight building standards, maintaining good ventilation rates in Schools and Offices and controlling ventilation equipment with the aim of reducing unnecessary ventilation and associated heat loss.
 
This neat wall mounted unit displays Carbon Dioxide levels as well as temperature and humidity - the LCD display is backlight by 3 colour LEDs to give you a clear indication of ventilation requirements.  The LCD displays GREEN when CO2 concentrations are GOOD, YELLOW when CO2 concentrations are less than ideal and RED when CO2 levels are too high.  These set point CO2 levels can be adjusted at the time of ordering:

The defaults are: Green  (optimal)

co2controller-green

Yellow (moderate) 1001ppm - 1400 ppm  

co2controller-yellow

Red  (poor) > 1400 ppm

co2controller-red
  
You can set the unit to switch an extract fan or other device when the CO2 concentration reaches a certain level - the set point level for this switch is controlled via an on-board dip switch that can be set at the time of installation.  The set point options are: 800ppm, 1000ppm, 1200ppm (default) and 1400ppm. A touch switch on the front of the unit allows you to override the relay to give you extra control - the switch allows the following: Automatic control with Alarm, Automatic control without Alarm, Always ON & Always OFF. The audible alarm is available to sound when the CO2 level rises above 1500ppm (the alarm set point can be changed at the time of ordering and can also be fully disabled if so desired).
