USER MANUAL WS590H Clas Ohlson

Mottagaren

The Ground Truth image displays a single, solid horizontal line. According to Rule 2 (UNDERSCORE & LINE RULES), this is a stylistic or background line, not a placeholder underscore. Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated placeholder underscores where none should exist in the GT. Hence, the OCR result is inconsistent with the Ground Truth.

Before starting

1. Insert batteries in the sensor first, then the receiver.
2. When inserting the batteries, place the sensor and the receiver unit close to each other to make sure that they synchronise.
3. Position the sensor and receiver within operating range of one another. NOTE! Despite the sensor being watertight, we recommend that it is not exposed to direct sunlight, rain and snow. The range of the units is affected by their position in relation to various obstacles or walls. Experiment until you find the best position.

Getting started

Installing the sensor

1. Remove the battery cover and insert 2x LR6 batteries.

2. The house code digit flashes for 8 seconds.

3. Whilst the digit is flashing, choose a house code (01-15) by pushing the "C/F" button repeatedly. Make sure that all the sensors in your system have the same house code.
4. Push "SET" to confirm the house code. The channel will flash for 8 seconds.
5. Select a channel (1-4) by pushing "C/F". Conform the channel by pushing "SET" or by not pushing any button for 10 seconds. If you select have one person we recommend that you
   only have one sensor, we recommend that you choose channel 1.
6. Temperature and humidity are shown on the display.
7. Alternate between Celsius and Fahrenheit by pushing "C/F".
8. When the sensor is installed it will send data with one minute intervals.
9. Choose another house code if your weather station can receive interference from other radio signals.
   • Factory presetting: house code = 01, channel = 1

Installing the receiver

Remove the battery cover and insert 2x LR6 batteries. Make sure that the plus and minus poles correspond to the markings in the battery compartment.

Synchronising the units

Automatic synchronisation:
1. The synchronisation starts automatically and lasts for about three minutes when you insert batteries for the first time.
2. During these three minutes the receiver emits an audible signal, intercepts the temperature radio signal and displays it on the readout.

NOTE! If the receiver does not receive any signals

within three minutes “---” appears instead of the temperature. Position the units closer together and start the automatic synchronisation again by removing and inserting the batteries once more.

Manual synchronisation (searching for signals)

If you add another sensor to the system or if the receiver loses the signal (digits for the outdoor temperature flash) you need to synchronise the system again.

1. Hold in the "Channel" button for three seconds when the receiver is in clock mode.
2. An audible signal lets you know that the synchronisation has begun.
3. The "CH" icon flashes and the receiver emits an audible signal when it has located the new sensor.
4. The temperature and humidity at the sensor are displayed on the readout.

NOTE! The synchronisation procedure lasts about three minutes. If the units have not found one another within that time, try new positions until the signal is received.

Setting the temperature alarm

You can decide if you want the alarm to warn you when the temperature reaches a certain level. You can set two alarms at the same time – one for the receiver and one for a sensor.

Indoor temperature alarm (receiver unit)

1. Press the Mode button repeatedly to get to the indoor temperature alarm setting mode.

2. The preset value 14°C or the latest setting will flash.

3. Press Hour or Minute to set desired temperature for when the alarm should sound.
4. Press Alarm repeatedly to switch between temperature alarms for high respective low temperature and also to activate the alarm.
5. Press Mode to confirm the setting.

Outdoor temperature alarm (sensor)

1. Press the Mode button repeatedly to get to the outdoor temperature alarm setting mode.
2. Press Channel to select a sensor.
3. The preset value 14°C or the latest setting will flash.
4. Press Hour or Minute to set desired temperature for when the alarm should sound.
5. Press Alarm repeatedly to switch between temperature alarms for high respective low temperature and also to activate the alarm.
6. Press Mode to confirm the setting.

When the temperature alarm sounds:

• Press any button to shut the alarm off. If you do not push any button the alarm will shut off automatically after one minute.
  • The alarm will sound when the temperature has reached the chosen value.
• The signal from the temperature alarm sounds different to the signal from alarm 1 and alarm 2 (the timed alarms).

Weather forecast

• This weather station can detect changes in the air pressure and thus
  forecast the next 12-24 hours' weather in a 30-50 km radius of the receiver. When the weather station is installed you can ignore it's forecasts for the first 12-24 hours as it needs some time to adjust to a new location before providing reliable forecasts.
• Absolute precision cannot be guaranteed. The weather forecast function has an accuracy of about 75%, due to the fact that it is designed to be used in many different types of area.
• If the weather station is moved to a location with a significant difference in the height above sea level, the batteries should be removed and then replaced again after about 30 seconds. By doing this the weather station is not fooled into detecting the difference in pressure and providing an incorrect forecast. Again, you should ignore the forecasts for the first 24 hours.

Remarks about the frost warning function:

• The snow symbol flashes when there is a frost warning.
- Activates when the outdoor temperature sensor is between -1.9°C and +2.9°C.
• The snow symbols stop flashing and stay constant when the temperature falls below -1.9^

External temperature sensor

The sensor is equipped with a socket for connecting the supplied external temperature sensor.

1. Connect the external weather probe to the sensor.
2. When the weather probe is connected, the following appears on the display:
   • Temperature at the probe.
   • Humidity at the sensor.
3. The "OUT" symbol appears on the sensor.

Batteries

If the batteries are exposed to very low or very high temperatures for a long time, they can lose their power thus reducing the range between the sensor and the receiver.

Receiver

1. If the low battery symbol appears on the display beneath the indoor temperature trend square, it is time to change the receiver battery. When the battery is low the following can happen:
2. The display dies.
3. The range between the sensor and receiver is reduced.
   • Data from the sensor is lost.
4. You will need 2 LR6 batteries for the sensor.
   NOTE! When you replace the receiver batteries all data is lost.

Sensor

1. If the low battery symbol appears on the sensor's display, it is time to replace the battery.
2. The low battery symbol also appears beneath the outdoor temperature trend square on the receiver.
3. You will need 2 LR6 batteries for the sensor.

Trouble Shooting Guide

Problem	Solution
The temperature on the sensor's display is not the same as the outdoor temperature displayed on the receiver.	Wait 1-2 minutes to make sure that the sensor and receiver are in sync. If not, synchronise the units again by holding in the "Channel" button for three seconds until a signal is heard.
The temperature on the sensor seems to be too high.	Make sure that the sensor is not placed in direct sunlight or next to a heat source.
The receiver cannot receive signals and display them.	- Synchronise the units again.- Move the units closer together.- The temperature could be under 30°C.- The sensor's batteries need replacing.- Make sure that the sensor is placed away from electrical interference.
The functions are strange or not working at all.	The instrument needs to be reset. Do this by replacing the batteries in both the sensor and receiver.
The display unit only shows a dash symbol when displaying the outdoor sensor's readings.	The sensor and the display unit are not in contact with each other:- Remove the batteries from both the sensor and the display unit and leave them out for about 1 minute.- Replace the batteries in the display unit first, and then the sensor, they should now be in contact with each other again.- Place the display unit and the sensor next to each other when carrying out this procedure.
