How to connect remote units to different channels
The PuroTemp Wireless Digital Hygrometer works with a maximum of 3 remote units to allow the reading of temperature and humidity on 3 separate humidifiers. All remote units need to be connected to different channels so that they do not interfere with each other.
- Open the battery compartment on the back of the remote unit.
- Move the cursor located inside the battery compartment to channel 1, 2, or 3.
- The number to which the remote unit is assigned will communicate with the corresponding channel on the base.
Wireless Communication Notes
- After installing the batteries, the base will automatically search for the signal from the remote unit for 3 minutes. During this period, the pictogram
indicating the current channel number will flash.Once the initial communication is established, this icon will stop flashing.
- After establishing communication between the base and each remote unit, they will automatically refresh every 60 seconds.
- If, for any reason, the remote units need to be resynchronized, press the "CH" button for 3 seconds so that the system restarts the synchronization process.
