How to Check Human Detection Sensor
Step 1 Check that Code no.11 or 21 is showing “0001”.
Step 2 Make the sensor that can detect a person.
Move back and forth and around for about 10 seconds under sensor activation.
Step 3 Check that Code no.12 or 22 can show “1” or more within 30 seconds after Step 2 is performed.
Step 4 Make the sensor that cannot detect a person.
Exclude the persons or animals (an object to be detected) from the detection area.
If the remote controller is placed within the detection area of the ECONAVI sensor, an inspector
must check motionless the display of the remote controller.
Step 5 After a while, check that Code no.12 or 22 can show “0”. (For about 30 seconds to 2 minutes)
How to Check Floor Temperature Sensor
Code no. 24: There is no problem if data is within the range of -20 to 60.
If data shows -35, the floor temperature is broken down.
