Description
CRT is used for CO2 and temperature measurement in indoor environments. CRT is a room transmitter for connection to regulator/control unit. It has two 0-10V analogue outputs. One for CO2 with measurement range 0-2000 ppm and one for temperature with measurement range 0-50°C.
The CO2 sensor in the CRT is maintenance-free in normal environments thanks to the built-in self-correcting ABC algorithm. The CO2 sensor has an expected lifetime of at least 15 years and does not require any additional calibration when used in normal indoor air applications. CRT-D-A-24 has a display that shows measured CO2 and temperature alternately.
CRT has two LED indicators and two pushbuttons. The LEDs indicate green for operation and offset adjustment of temperature and red for calibration of CO2.
Installation
CRT is installed on the wall of the room to be controlled. Avoid installation in direct sunlight or near heat or cooling sources. If it is installed over a junction box/cable pipe, these must be sealed to avoid affecting measurement results. Screws with specially adapted head size are attached.
