Note:

1 The joint of trunking ports and sensor substructure need to be used the PVC terminals to transit when you install this sensor. In order to ensure the trunking and sensor could be in axis of the same line, we suggest you'd better to install the substructure firstly then nail the trunking.

2The horizontal distance from sensor to air condition air distributor should be more than 1.5 m, and to the ceiling air distributor should be more than 0.5m.

3  In order to prevent the isolation floor of cold air through the trunking to impact the actual measurement,it should be added the PVC terminals at the upper port of trunking or install the sensor in side of the trunking.
