General

 

The IAQ-sensor product 

aSENSE mIII 

is used to measure indoor air carbon dioxide 

and carbon monoxide concentrations. It is a very flexible controller with 
programmable outputs for both relay- and linear control of e.g. mixed air dampers, 
humidifier and fans. The measured values are shown on the display. 
 
The unit can alternatively be connected to common VAV (Variable Air Volume) 
controllers, or Direct Digital Control (DDC). The linear output functions are pre-
programmed. All functions can be modified from a PC with the software UIP (version 
4.3 or higher) and the RS232 communication cable.
