PRODUCT DESCRIPTION
Programmable regulators with relay outputs are designed to measure temperature and relative humidity of air, to measure
concentration of CO2in air, to signal alarms and control of external devices. Regulators can be used in a chemical non-aggressive
environment.
The CO2concentration is measured using the maintenance free sensor. The unique patented auto-calibration procedure
compensates aging of the sensing element and guarantees outstanding high reliability and long-term stability.
Two output relays functions can be set from regulator keyboard or from computer. Each relay can be assigned to one of
measured or computed value (dew point temperature, absolute humidity, specific humidity mixing ratio and specific enthalpy).
Setting of delay, hysteresis, audible alarm is enabled for each relay. Measured and calculated values are displayed on a two-line
display. The visual indication of the CO2concentration is provided by three LEDs to the left side of the display. Using TSensor
software can be all regulator parameters set. To connect to PC is used USB adapter ATS-AC17 (optional accessories).

INSTALATION AND OPERATION
The mounting holes and connection terminals are accessible after unscrewing the four screws in the corners of regulator and
removing the lid. Devices have to be mounted on a flat surface to prevent deformation. Pass cables (external diameter 3 to 6.5 mm)
through released glands and connect wires according to diagram. Wire cross-section choose from 0,14 to 1.5mm2. Tighten glands
and screw the lid. Insert attached plugs into unused cable glands too. Unpack the external CO2probe (AT-VLS-104DR) and
connect it to the device. Pay attention to mounting the device and probe, because incorrect choice of working position or place of
measuring could adversely affect accuracy and long-term stability of measured values.
Actual parameters settings of each relay can be displayed by pressing of „ ▲“ key. To change any parameter, press the „Set“ key,
enter password (default 0000) and set required value. Then click on „Set“ and pressing „Esc“ key exit setup mode. To change the
password and to set all other parameters (alarm settings, limits of CO2indication, used units, computed value selection etc.) is
used Extended setting mode (see manual).
After switching the device starts internal test. During this time (about 20 s) LCD display shows ---- instead of CO2concentration
value.
Devices don´t require special maintenance. We recommend you periodical calibration for validation of measurement accuracy.
ERROR STATES
Device continuously checks its state during operation and if an error appears, it is displayed relevant code:
Err 0 –it is a serious error, please contact distributor of the device
Err 1 –measured value (except the concentration CO2) or calculated value is over the upper limit
Err 2 –measured or calculated value is below the lower limit or concentration CO2measurement error occurred
Err 3 –it is a serious error, please contact distributor of the device
Err 5, Err 6 –there is problem with assigned value to output relay
Err 9 –inserted password is not valid
SAFETY INSTRUCTIONS
- Humidity and temperature sensors of the regulator cannot be operate and store without a filter cap.
- Temperature and humidity sensors have not to be exposed to direct contact with water and other liquids.
- It is not recommended to use the humidity regulators for long time under condensation conditions.
- Take care when unscrewing the filter cap as the sensor element could be damaged.
- The regulator must be turned on for at least 24 hours in order to start the automatic calibration of the CO2
sensor.
- Don’t connect or disconnect devices while power supply voltage is on.
- Installation, electrical connection and commissioning should be performed by qualified personnel only.
- Devices contain electronic components, it needs to liquidate them according to currently valid conditions.
