Determine the location for the installation of the Remote Temperature Sensor. The following items must be observed.
1.
Select a place where the remote temperature sensor will detect an average temperature of the room and where the sensor
will not be subject to direct sunlight, heat sources, or air flow from the air conditioning unit etc.
2.
Install the sensor within the length of cable provided (10m). (The cable cannot be extended. If extended, it may cause
operational malfunction due to noise.)

Fitting the Remote Temperature Sensor in wall space
1.
Select a location with a flat surface on an interior wall approximately 5’ (1.5m) off the floor.
2.
Drill a 7/16" hole where you want the sensor mounted.
3.
Pull the cable through the hole.
4.
Be sure the wall interior is insulated behind the sensor. In-wall drafts can affect the temperature reading.
5.
Clean the wall surface from any dust or filings to make a clean mounting surface.
6.
Remove the mounting tape from the back of the sensor rim and push the sensor firmly into the 7/16” hole until the double
stick tape adheres firmly to the wall.
7.
Remove the sensor protector (Fig.2) before putting sensor into service.
Note: Once installed the sensor is difficult to remove and may damage the wall.

1.
Remove the existing connection from CN20 on the Mitsubishi Electric unit PCB (Fig.3).
2.
Connect the remote temperature sensor CN20 connector to the Mitsubishi Electric PCB.
3.
Test the sensor at the controller to be sure of your connections and sensor operation.
