Replacing the HTM10 Module
CAUTION Handle the HTM10 module carefully. When reinstalling the transmitter
body to the mounting base, avoid touching the module or the
HUMICAP ® sensor.
To replace the module:
1.
Disconnect the transmitter body from the mounting base.
2. With your fingers, push apart the two plastic holders that hold the
module. Pull out the module. Keep the module straight while
pulling it out, otherwise the pins may twist in the connector and
damage it.

3. Take the new module and align the pins to the connector on the
transmitter’s component board.
4. Push down on the module so that the plastic holders clip into place.
Try not to tilt the module, so that the pins will meet the connector
straight on.
5. Reconnect the transmitter to the mounting base.
6. Verify that there are no errors when the transmitter starts up. If
there are, see section Error Messages on page 73.
