CO2-, temperature- and
relative humidity transmitter
General
tSENSE VAV for wall mounting measures indoor air carbon dioxide concentration, temperature and
relative humidity in rooms. tSENSE VAV is available with colour touch display (LCD).
The unit connects to Direct Digital Control (DDC).
Linear outputs are pre-programmed as CO2-, temperature- and relative humidity transmitter.
Measuring ranges can be modified via touch display, from PC (Windows) software UIP (version 5 or
higher) and USB communication cable, alternative via Modbus or BACnet.

The voltage level of OUT1 is the result of the largest demand from Proportional-bands.
Out1_a/Out1_b/Out1_c => OUT1
The voltage level of the one of Out1_a, Out1_b or Out1_c which has the highest voltage level
provides the voltage level of OUT1.
The values below are defalt values.
5V (Out1_c) –0V (Out1_d Disabled) = 5V => OUT1
The (e.g.) VAV valve opens from minimum set-point position, with full opened state at the maximum

Temp protection (Out1_d) Enabled
10V (Out1_a) –10V (Out1_d) = 0V (OUT1).
The voltage level of the one of Out1_a, Out1_b or Out1_c which has the highest voltage level is in this
case 10V (Out1_a), minus 10V (the voltage level of Out1_d) provides the voltage level of OUT1 which
is 0V.
Despite high value of CO2(1205ppm), OUT1 is 0V (no signal to ventilation system to start), because
of low value of Out_b (16.4°C) when temperature protection Out1_d is Enabled.
NOTE!
Out_d (sub) in display picture: (sub) = subtraction, (Temperature protection)

Communication settings
Protocol
When the sensors RS-485 Protocol parameter is set to “Auto”, the sensor selects protocol depending on
the protocol used on the network it is connected to. After power on, the sensor then listens to the traffic on
the RS-485 network. If the sensor detects valid BACnet, or Modbus messages, the sensor will start to use the
detected protocol.

NOTE!
Zero Calibration: procedure requires calibration gas with CO2value 0ppm
Zero Calibration Kit is used to zero calibrate CO2sensors. The unit produces CO2free air from
ambient air.
Background Calibration: uses ABC (Automatic Baseline Correction) target, default value is 380ppm,
as calibration target. (Background Calibration button as option.)

Target Calibration (Background CO2 level): default value is 400ppm.
e.g. The ABC requires that the sensor is exposed to fresh air (at background level of CO2 at least once
per ABC period). If sensor is operated in environments that never reaches the background level, it
might still be possible to benefit from ABC function by adjusting target level.

ABC: the function makes the sensor automatically adjust for any drifts in sensor reading due to e.g.:
calibration misalignment due to vibration/shock from transportation and/or installation
component aging
dust accumulation
degradation of reflective surfaces in the optical system
The ABC makes use of the fundamental fact that there is a background level of CO2in the atmosphere
that is fairly constant, currently close to 400ppmvol, and that for many applications the CO2level will
reach the background level at some points in time.
NOTE!
For the ABC time counter to work properly, the electrical power supply to the sensor needs to be
continuously ON for at least four (4) hours.
