aSENSE Ind Display 3%

aSENSE Ind 3% is an advanced transmitter for installation in the climate zone. It measures both CO concentration and temperature. The data is transmitted to a BMS system or controller and can be configured with UIP Software. The unit is prepared for Modbus. The unit can also be used as a safety product to save lives.

  • Maintenance-free in normal applications
  • Contributes to lower energy costs
  • Cost-efficient RS485 communication as an option

aSENSE Ind 3% Disp RL is a key component for climate control of buildings. The transmitter is flexible and suits many different ventilation strategies. It is also a cost efficient gas alarm sensor for spaces where carbon dioxide gas is a potential danger.

The aSENSE Ind 3% Disp RL is designed to control ventilation by transmitting the measured carbon dioxide and temperature value to the Master of the system or DDC to save energy and ensure a good indoor environment.
