Page 84 APPENDIX: PROBES CONNECTION To assure the utmost comfort, the control system needs reliable information, which can be obtained provided the sensors have been installed correctly. Sensors measure and transmit all variations encountered at their location. Measurement is taken based on design features (time constant) and according to specific operating conditions. With wiring run in raceways, the sheath (or pipe) containing the wires must be plugged at the sensor's terminal board so that currents of air cannot affect the sensor's measurements Ambient probes (or ambient thermostats)

Page 99 APPENDIX: PROBES CONNECTION To assure the utmost comfort, the control system needs reliable information, which can be obtained provided the sensors have been installed correctly. Sensors measure and transmit all variations encountered at their location. Measurement is taken based on design features (time constant) and according to specific operating conditions.With wiring run in raceways, the sheath (or pipe) containing the wires must be plugged at the sensor's terminal board so that currents of air cannot affect the sensor's measurements.

Page 119: Automatic Mode
M12927CA OPERATIVE MODES When the instrument is powered, it starts immediately to work according to the parameters values loaded in its memory. The instrument behaviour and its performance are governed by the value of the stored parameters. At power ON the instrument can start in one of the following mode depending on its configuration: Automatic Mode In Automatic mode the instrument drives automatically the control output according to the parameter value set and the set point/measured value.
