Accessing the internal humidity sensor AES1-HT-Ax

MAINTENANCE

1. With a Phillips-type screw driver of size #2, un-tighten the front holding

screw to loosen the front part to the mounting plate. This screw is located
on the front lower side of the unit. (TCI models only).

2. Locate the notch in the bottom of the front cover. Using the screw driver,

carefully lift the front cover until the cover loosens from the mounting-plate.

3. Slide the front cover off to expose the circuit board and pins for the AES1-

HT-Ax sensor. See Figure 22-1.

4. If present, slide the existing AES1-HT-Ax out of the pins and replace with a

new one.

5. Follow the installation instructions starting on Page 10 to put back

together.

6. Change parameters according to Table 21-1.
