XVI.3. PT1000 temperature sensor
The temperature sensors are PT1000 type. The location of each temperature sensor is shown in chapter VII.1 General composition .
The curve below shows the resistance characteristic of the sensitive element as a function of its temperature.
The sensor is simply checked using an ohmmeter and a reference thermometer. The resistance measured at the terminals of the
(disconnected) sensor wire must correspond to /- 3% of the resistance value tabulated above for the equivalent
temperature measured by the reference sensor. If necessary, the sensor must be replaced. If the sensor check is good, but the
control displays an incorrect value, the problem may be due to faulty connectors/wires or an incorrect offset that has been set.
XVI.4. CO2 sensor
The CO2 sensor transmits the image of the CO2 concentration (ppm) in the extracted air as a 0-10V analogue signal that can be
interpreted by the controller:
