12.7 Replacing a T/H Sensor (Building Scenario)

Prerequisites

●

A T/H sensor needs to be replaced.

●

A spare T/H sensor of the same model is available and functional.

●

Tool: Phillips screwdriver, scissors

Procedure

Step 1 On the home screen of the display module, tap Shutdown and turn off the unit

switch in the PDF.

NO TICE

Exercise caution because the unit is still energized after it is shut down on the

home screen of the display module.

Step 2 Remove the indoor return air filter.
Step 3 Remove the indoor return air T/H sensor. Cut off the cable tie that secures the

cable, and remove the cable from the T/H sensor.

Figure 12-11 Removing a T/H sensor

Step 4 Remove the outdoor intake air T/H sensor. Remove the screws from the sheet

metal fastener of the T/H sensor.
