CF5

/ temperature transmitter

General

The IAQ-sensor product CF5 is used to measure indoor air carbon dioxide

concentration and temperature in rooms. The CF5 is available both with and without

display, (LCD). Both are available for wall mounting as well as for duct mounting.

The unit is designed for connecting to Direct Digital Control (DDC). The linear output

functions are pre-programmed as CO

and temperature transmitters with jumper

selected outputs 0-10 V / 2-10 V / 0-20 mA / 4-20 mA. The measuring ranges can be

modified from a PC (Windows) and use of the software UIP (version 4.3 or higher)

together with the RS232 communication cable.

Jumper Start point selection jumper Position Function 0% Jumper top position provides 0Vdc or 0mA start point for Out(1), Out(2) (0-20mA or 0-10V). 20% Jumper bottom position provides 2Vdc or 4mA start point for Out(1), Out(2) (420mA or 2-10V). Current NOTE! The start point jumper is missing on some models! Connection in position “Current” provides 0/4-20mA output range for Out(1).

Error code and action plan Bit # 0 Error Error description code N/A Fatal Error Suggested action Try to restart sensor by power OFF/ON. Contact local distributor 1 2 Reserved 2 4 Algorithm Error. Indicate wrong EEPROM configuration. Try to restart sensor by power OFF/ON. Check detailed settings and configuration with UIP software version 4.3 and higher. Contact local distributor. 3 8 Output Error Detected errors during output signals calculation and generation.

Remark: If several errors are detected at the same time the different error code numbers will be added together into one single error code! PLEASE NOTE! The sensor accuracy is defined at continuous operation (at least 3 weeks after installation) Maintenance The CF5 is basically maintenance free. An internal self-adjusting calibration function takes care of normal long term drift associated to the CO2 sensor.
