Mounting and usage

2 Wire current output circuit

Notice

Wall mounting humidity & temperature transmitter is kind of precision

manipulation and careful maintenance is necessary for normal running.

So be sure to note:

1. The mounting direction of soleplate and base should be attended.

2. Be sure to cut off the power supply before mounting and changing transmitter.
