Getting Started
Position the main unit, rain gauge, and thermo sensor within effective range:
- Rain gauge - 328 feet / 100 meters
- Thermo sensor - 98 feet / 30 meters
IMPORTANT: It is recommended that you follow the sequence below when setting up the units:
- Set up the main unit.
- Set up the rain gauge, then press and hold SEARCH on the main unit and wait until you receive a signal.
- Set up the thermo sensor, then press and hold SEARCH on the main unit and wait until you receive a signal.
- In the event that you do not obtain a signal from a remote unit, please repeat the process above.
Main Unit Setup
- Insert the batteries, matching the polarity ([plus-sign] and [minus-sign]) as shown in the battery compartment. Diagram Description: Shows battery insertion into the main unit.
- Press RESET, or press and hold SEARCH on the main unit to initiate operation. The reception icon on the main unit will blink while it is searching for the sensor or rainfall gauge.
NOTE: Every time the battery in the main unit is changed, repeat installation before use.
Rain Gauge (PCR122) Setup
- Insert the batteries, matching the polarity ([plus-sign] and [minus-sign]) as shown in the battery compartment. Diagram Description: Shows battery insertion into the rain gauge.
- Mount the rain gauge on a level surface. Diagram Description: Shows the rain gauge being placed on a level surface.
- Put drops of water on the cross at the base to check the leveling. Ensure the water spreads evenly. Diagram Description: Illustrates checking the level using water drops on a crosshair. One diagram shows an incorrect (X) leveling, and another shows correct (✓) leveling.
- Use the metal ring to adjust the level of the rain gauge. Diagram Description: Shows adjusting the rain gauge level with a metal ring.
- Remove the fiber tape from around the bucket assemblies. Diagram Description: Shows removing protective tape from the rain gauge's internal bucket mechanism.
Thermo Sensor (THN122N) Setup
- Insert the batteries, matching the polarity ([plus-sign] and [minus-sign]) as shown in the battery compartment. Diagram Description: Shows battery insertion into the thermo sensor.
- Set the channel switch to any channel. The switch is located in the battery compartment.
- Press RESET on the sensor.
- Close the remote sensor battery compartment.
- Secure the sensor in the desired location using the wall mount or table stand. Diagram Description: Shows the sensor being mounted using either a wall mount or a table stand.
For best results:
- Insert the batteries before you mount the sensor.
- Place the sensor out of direct sunlight and moisture.
- Do not place the sensor more than 98 feet (30 meters) from the main (indoor) unit.
- Position the sensor so that it faces the main (indoor) unit, minimizing obstructions such as doors, walls, and furniture.
Place the sensor in a location with a clear view to the sky, away from metallic or electronic objects.
Position the sensor close to the main unit during cold winter months as below-freezing temperatures may affect battery performance and signal transmission.
You may need to experiment with various locations to get the best results.
Standard Alkaline batteries contain significant amounts of water. Because of this they will freeze in low temperatures of approximately 10°F (-12°C). Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -40°F (-40°C).
Wireless ranges can be impacted by a variety of factors such as extremely cold temperatures. Extreme cold may temporarily reduce the effective range between the sensor and the base station. If the unit's performance fails due to low temperature, the unit will resume proper functioning as the temperature rises to within the normal temperature range (i.e. no permanent damage will occur to the unit due to low temperatures).
Data Transmission
Data is sent from the remote thermo sensor approximately every 78 seconds and from the rain gauge approximately every 94 seconds. The reception icon shows the status.
| THERMO SENSOR | RAIN GAUGE | DESCRIPTION |
|---|---|---|
| [house-icon] [arrow-right] [house-icon] | [rain-icon] [arrow-right] [rain-icon] | Searching |
| [house-icon] [arrow-right] [rain-icon] | [rain-icon] [arrow-right] [rain-icon] | Connected |
| [house-icon] [arrow-right] [house-icon] [arrow-right] [rain-icon] | [rain-icon] [arrow-right] [rain-icon] | Disconnected |
If the main unit display shows that the thermo sensor or rainfall connector is disconnected without obvious reason, press and hold SEARCH to enforce an immediate search.
If that fails, check:
- The remote rain gauge and thermo sensor are still in place.
- The batteries of the main unit, rain gauge, and thermo sensor are still good. Replace them if necessary.
- The transmission is within range and the path is clear of obstacles and interference. Shorten the distance if necessary. Then press and hold SEARCH again.
Low Battery Warning
There are 3 low-battery indicators. Replace the batteries immediately when the respective indicator lights up.

Caution: Other sensors using the 433 MHz transmission frequency may influence the rainfall reading. Please avoid placing those sensors too close to the unit.
Total Rainfall
The total rainfall is displayed on the 2nd line of the LCD display. To display the commencing date of the total rainfall record, press SINCE. The date will appear on the 1st line of the display. Press again to show the commencing year.
To clear the existing commencing date and reset it to start again, press and hold SINCE. The total rainfall will now be equal to the today rainfall and the unit will start again to collect the rainfall data.
Rainfall Alarm
The rain alarm value can be displayed at any time by pressing [button: •].
To set the rainfall alarm:
- Press and hold [button: •] for two seconds.
- Use [arrow-up] or [arrow-down] to set the desired value.
- Press [button: •] to confirm. The alarm will be activated. The rain alarm indicator will light up.
The alarm will go off for one minute when the rainfall reaches the preset value and the rain alarm indicator will flash. A reminder beep will be emitted every minute. Once the rain alarm is on, the indicator will not stop flashing unless [button: •] is pressed or the rain alarm value is changed. To stop the alarm and reminder beep, press any button or change the rainfall alarm value.
To deactivate the alarm, press [button: •].
