Frequently Asked Questions - FT0203 Cotech

How do I connect the sensors to the indoor unit?

Insert batteries into all sensors before powering the indoor unit. When the indoor unit is turned on, it automatically searches for nearby sensors. Do not press any buttons during the search. If a sensor is not found, press and hold CHANNEL/+ for 3 seconds, select the sensor type, and confirm with MODE/SET.

What should I do if the display shows '---' for a sensor?

The weather station has lost contact with that sensor. First, check the distance (should be between 1.5 m and 30 m) and remove obstacles. Ensure the sensor's LED flashes every 60 seconds. Replace batteries if needed. Then perform a manual search by pressing and holding CHANNEL/+ for 3 seconds.

How do I change the units of measurement (e.g., °C to °F)?

Press and hold MODE/SET for 3 seconds to enter settings mode. Navigate with CHANNEL/+ and HISTORY/- to UNIT SET. Press MODE/SET to enter, then use the +/- buttons to toggle between °C and °F, or other units for wind, rain, and pressure. Confirm with MODE/SET.

How do I set an alarm for temperature or wind speed?

Press and hold MAX/MIN/ALARM for 3 seconds to enter alarm mode. Then press and hold MODE/SET for 3 seconds to start setting. Use CHANNEL/+ and HISTORY/- to adjust values, and press MAX/MIN/ALARM to toggle alarm ON/OFF. Press MODE/SET to confirm each step.

How can I calibrate the temperature sensor?

Press and hold MODE/SET and CHANNEL/+ simultaneously for 5 seconds. The indoor temperature will flash. Use +/- to adjust it to match a reference thermometer. Press MODE/SET to calibrate outdoor sensors (channels 1-8). A step of 0.1°C is available.

Where should I mount the rain gauge and anemometer?

Mount the sensors away from obstructions (at least 4 times the height of nearby objects). Ensure the anemometer's S marking faces south. The rain gauge must be level and stable. Place the thermometer/hygrometer in the shade about 1.5 m above ground.

How do I reset the max/min recorded values?

In normal mode, press MAX/MIN/ALARM to show MAX or MIN values. Press and hold MODE/SET for 3 seconds until CLR flashes. The values will reset. Alternatively, set CLR to ON in settings for automatic daily reset at midnight.

Searching for sensors and checking the sensors' functionality

When the indoor unit is turned on, an automatic search for nearby sensors will begin. The search is indicated by ☐ If you have more than one thermometer/hygrometer, the display will alternate between these as they are registered. When the symbol disappears, you can test that the sensors are working.

i Information

If, when searching, the weather station is unable to find a sensor, or if it loses contact with a sensor, “---.” is shown on the display. Perform a manual search for a sensor:

1. In normal mode, press and hold [ CHANNEL/+ ] for 3 seconds. "REG" appears on the display.
2. Press [ CHANNEL/+ ] or [ HISTORY/- ] to select thermometer/hygrometer (CH1-8), anemometer (WIND), rain gauge (RAIN), all sensors (ALL) or, to cancel the search, (NOT). Confirm your selection by pressing [ MODE/SET ].

Anemometer

1. Test the sensor for wind speed by spinning the cups. Check that the value shown on the display changes.

Rain gauge

Rock the rain gauge's measuring cup back and forth. Each time the measuring cup tips over represents 0.3 mm of precipitation. Check that the value shown on the display changes.

1. Test the sensor for wind direction by changing the position of the weather vane. Check that the direction shown on the display changes.

Thermometer/hygrometer

Place the sensor close to the indoor unit, and leave it lying there for approx. 30 minutes so that the temperature stabilises. Read the values for the temperature and humidity, and compare these. The temperature values should be within 1 °C (accuracy ±0.5 °C) and the humidity values should be within 6 % (accuracy ±3 %).

If you have any additional thermometers/hygrometers connected, press [ CHANNEL/+ ] (2) repeatedly to switch between these.

If the values lie outside of these limits, they can be adjusted on the indoor unit. See the Calibration section.

i Information about air pressure

The weather station can display air pressure in two different ways: ABS – absolute (measured) and REL – relative (adjusted to sea level).

• The relative value is used by meteorologists in order to be able to compare the air pressure in different locations.
• The normal air pressure at the level of the sea's surface varies according to geographical location, but has an average value of 1013.2 hPa. Low pressure is generally considered to be below 990 hPa, and high pressure is above 1020 hPa.
• Because air pressure decreases with altitude, the relative value will generally always be higher than the absolute value.

Sound settings for key presses and alarm

In normal mode, press and hold [ HISTORY/– ] for approx. 3 seconds to turn the sound on or off. “BUZZON” (when turned on) or “BUZZOFF” (when turned off) will be shown on the display.

• To permanently silence the alarm, press one of the other buttons: [CHANNEL/+], [MODE/SET], [MAX/MIN/ALARM] or [HISTORY/-].

Calibration

• If the connected sensors display inaccurate values, they can be recalibrated. To calibrate the sensors properly, you must have reference values from meters/sensors that you know give accurate readings.
• The calibrated value can only be displayed on the indoor unit. The external thermometers/hygrometers always show the uncalibrated value.
• The range for relative humidity is always between 10 and 99% . It is not possible to adjust the value beyond this range.
• Press [ CHANNEL/+ ] or [ HISTORY/− ] to increase or decrease the selected value. To change the value more quickly, press and hold the button for 3 seconds.
• Press [ MAX/MIN/ALARM ] to reset the adjusted value.
• To complete the calibration and return to the normal display mode, press [SNOOZE/LIGHT] or wait for 30 seconds.

8. Adjust the value to correspond with your reference value. The value can be changed in steps of 0.1 hPa.

Final mounting

Information

We recommend that you familiarise yourself with the weather station and its sensors before you mount the devices in their final locations. This gives you the opportunity to easily calibrate the sensors and to test the various functions of the weather station.

Choice of location

Things to consider before you mount the devices:

• The rain gauge should be cleaned once per year, and batteries must be replaced once every two years. Ensure, therefore, that the sensors are mounted in easily accessible locations.
• Ensure that the rain gauge and anemometer are not obstructed by any nearby trees or buildings. The general rule is to mount the sensors at a distance that is at least 4 times the height of nearby obstructions – e.g. if a building is 6 m high, the sensors should be mounted (4 × 6 =) 24 m away.
• Avoid radiated heat from nearby buildings, roofs, etc. Generally speaking, temperature sensors should be mounted in the shade approx. 1.5 m above the ground.
• Test the sensors in their intended locations before mounting them. The range can be affected by the type of obstacles located between the transmitter and the receiver (e.g. a concrete wall will interfere with the signal more than a plasterboard wall).
• Other wireless equipment using the same frequency band (433 MHz) can also have a negative impact on the transmission range.

In the event of transmission range problems, try the following:

• Turn off any other existing wireless equipment to check whether this is the cause of the problem.
• Shorten the distance between the sensors and the indoor unit, and reduce the number of obstacles (walls, items of furniture, etc.) between the devices.

Indoor unit

• The indoor unit has integrated sensors for temperature, humidity and air pressure. Be sure, therefore, to place the unit so that it is not located close to heaters, cookers, or other heat sources.
• Avoid placing the unit next to metal objects (such as metal window frames) as this may interfere with the radio reception.

The weather station can be used with its table stand or mounted on a wall using its eyelet.

Anemometer

1. Localise the marking on the underside of the anemometer. Ensure that the S marking is aligned so that it faces south.

• Check and clean the rain gauge once every 3 months.

Troubleshooting guide

The wireless sensors are not transmitting any data to the indoor unit.The display shows “--.-”.	When the indoor unit loses contact with a sensor, either “--.-” or “--” is shown on the display.To search for sensors: Press and hold [ CHANNEL/+ ] for 3 seconds. Press [ CHANNEL/+ ] or [ HISTORY/– ] and select the sensor that is to be reconnected. Confirm your selection by pressing [ MODE/SET ]. The symbol appears while the search is taking place. When the sensor has been found, the symbol disappears and the value appears on the display.Check the distance between the sensors and the indoor unit. This distance should normally be between 1.5 m and 30 m.Try placing the sensors higher up.Check that the sensors’ displays are working/LED indicators are flashing (once every 60 seconds).Insert new batteries into the sensors. In areas with a cold climate, lithium batteries are recommended.Check that the batteries in the indoor unit are not flat. Even if the indoor unit is being powered by mains electricity, flat batteries can also cause problems when it tries to find the sensors.Check that the radio signal is not subject to interference from nearby metal constructions, etc.Move the indoor unit away from other electronic devices, such as routers, computers and televisions.
The temperature sensor shows daytime values that are too high.	Check that the thermometer/hygrometer is mounted in a location that is shaded from the sun. If possible, mount the sensor in a north-facing direction.
The indoor and outdoor sensors show different values.	Allow the sensors to stabilise for up to 1 hour.The temperature values should be within 1 °C (accuracy ±0.5 °C) and the humidity values should be within 6 % (accuracy ±3 %).Where necessary, adjust the sensors in the indoor unit (see the Calibration section).
The contrast of the display is poor.	Replace the batteries in the unit.
The background lighting does not change colour as expected.	Check the settings (see the Settings/adjustments section).If the background lighting is to reflect the outdoor temperature, ensure that the outdoor sensor is set to channel 1.
The display indicates precipitation although it is not raining.	Make sure the rain gauge is mounted in a stable manner.If the gauge is not properly fitted (e.g. attached to an unsteady mast), the sensor can transmit incorrect values.
