Frequently Asked Questions - 00523 AcuRite

How do I set up the AcuRite 00523 thermostat?

Insert 2 AAA batteries into the main unit and the outdoor sensor. Place the sensor outdoors in a shaded area. The devices will automatically sync within a few minutes.

Why is my outdoor sensor not displaying data?

Ensure the sensor is within range (165 ft open air) and batteries are fresh. Press and hold the CHANNEL button on the main unit to resync.

Can I add multiple outdoor sensors?

Yes, the 00523 supports up to two sensors. Set each sensor to a different channel using the switch inside the sensor battery compartment.

How do I read the trend arrows?

Upward arrow means temperature/humidity is rising, downward means falling, horizontal means stable. Arrows update every 60 minutes.

What does the min/max memory feature do?

It records the lowest and highest temperature and humidity readings since last reset. Press MIN/MAX to view, hold to clear.

Is the device water resistant?

The main unit is for indoor use only. The outdoor sensor is water-resistant but should be placed under an eave to avoid direct rain.

How accurate is the humidity reading?

Humidity accuracy is ±5% RH under normal conditions. For best results, keep the sensor away from direct sunlight and heat sources.

Can I mount the main unit on a wall?

Yes, use the built-in keyhole mount on the back. Insert a screw into the wall and hang the unit. Ensure the screw head is appropriate.

Why does the display show '---'?

This indicates lost communication with the sensor. Move the sensor closer, check batteries, or resync by pressing the CHANNEL button.

How do I replace batteries without losing data?

Replace batteries within 5 minutes to retain memory. If longer, min/max values will reset but current readings resume immediately.

Select Degrees Fahrenheit or Celsius

To select between degrees Fahrenheit (°F) or Celsius (°C) temperature units, press and release the "°C/°F" button, located on the back of the thermometer display.

PLEASE DISPOSE OF OLD OR DEFECTIVE BATTERIES IN AN ENVIRONMENTALLY SAFE WAY AND IN ACCORDANCE WITH YOUR LOCAL LAWS AND REGULATIONS.

BATTERY SAFETY: Clean the battery contacts and also those of the device prior to battery installation. Remove batteries from equipment which is not to

be used for an extended period of time. Follow the polarity (+/-) diagram in the battery compartment. Promptly remove dead batteries from the device. Dispose of used batteries properly. Only batteries of the same or equivalent type as recommended are to be used. DO NOT incinerate used batteries. DO NOT dispose of batteries in fire, as batteries may explode or leak. DO NOT mix old and new batteries or types of batteries (alkaline/standard). DO NOT use rechargeable batteries. DO NOT recharge non-rechargeable batteries. DO NOT short-circuit the supply terminals.

Display Placement

Place display in a dry area free of dirt and dust. Display is magnet mountable and has a fold-out stand for tabletop use. For wall mounting, hang using the keyhole located on the back of the unit.

Sensor Placement

• Both sensors will work in either the refrigerator or freezer, however the default alerts are set based on the sensor's indicated use (see page 2).
  • Each sensor is equipped with a silicon band to securely attach to a wire shelf.
  • Each sensor also includes a detachable suction cup that can be used to attach the sensor to the interior surface of the refrigerator. Please note: suction cups do not adhere well to freezing surfaces.
• Display and sensors must be located within 75 ft (23 m) of each other.

Using the Thermometer

High & Low Records

The thermometer displays high and low temperature records for all-time and the past 24 hours (rolling). All-time records reflect the highest and lowest temperatures recorded since the batteries were inserted or the records have been cleared. High and low records for the past 24 hours are shown on the display, by default.

Press and the release the “^” or “∨” button to view all-time records. If no buttons are pressed for 5 seconds, the display will return to normal operation mode.

To clear the high records, press and hold the “^” button for 5 seconds while viewing the record you wish to clear. To clear the low records, press and hold the “∨” button for 5 seconds while viewing the records you wish to clear. Dashes display to confirm you have cleared the record(s).

Programmable Alarms

Programmable alarms notify you audibly and visually when temperatures exceed your preset minimum / maximum temperature range. An alert is triggered when a temperature is out of range for longer than 5 minutes. This prevents false alarms due to the fridge/freezer door being held open while new items are being loaded/unloaded.

To enable alerts for both sensors, press and hold the “◀” button for 5 seconds until “◀” is shown next to the current temperatures.

To enable alerts for a select sensor, press the “ 🔊” or “ ✕ ” button first, then press the “ 🔕 ” button once to enable alarm. Disable the alarms at any time by following the same steps until “ 🔕 ” is shown next to the current temperature. The default temperature alarm settings for the refrigerator thermometer are minimum 33°F / maximum 40°F. The default temperature alarm settings the freezer thermometer are minimum -20°F / maximum 32°F.

To customize temperature alarms:

1. Select the sensor you want to customize by pressing the "◇" or "◆" button.
2. Press and release the "SET" button; the minimum temperature alarm setting will blink.
3. Press the “^” or “√” button to increase or decrease the minimum temperature alarm setting.
4. Press the "SET" button to confirm the minimum temperature alarm setting.
5. Press the “^” or “√” button to increase or decrease the maximum temperature alarm setting.
6. Press the "SET" button to confirm the maximum temperature alarm setting.

NOTE: When thermometer is in normal operating mode (not in alarm setup mode), the min/max readings display the highest/lowest temperatures from the previous 24 hours.

Calibration

The temperature readings can be calibrated on the display to improve accuracy. Calibration can improve accuracy when product placement or environmental factors impact your data accuracy.

1. To access calibration mode, press AND HOLD the “^”, “∨” and “SET” buttons simultaneously for at least 5 seconds.
2. To adjust the currently selected item, press and release the “^” or “∨” buttons to calibrate the data value higher or lower from the actual reading.
3. To save your adjustments, press and release the "SET" button to adjust the next reading. The calibration indicator (wrench) will remain under the calibrated values.

After 12-15 seconds of inactivity, the display will save the adjustments and exit calibration mode. Note: Calibrations will be erased if the batteries are removed.

Troubleshooting

Temperatureis showing dashes	Relocate the display and/or the sensors.The units must be within 75 ft (23 m) of each other.Flashing of the temperature is generally an indication of wireless interference. Perform a hard reset to gain a strong connection between the units:Bring all 3 units together, side-by-side.Remove all batteries from all 3 units.Reinstall batteries in thermometer display first.Reinstall batteries into sensor #1.Reinstall batteries into sensor #2.The display should read temperatures from both sensors almost instantly.
Inaccurate temperature	Use standard alkaline batteries (or lithium batteries in sensor when temperature is below -4°F/-20°C). Do not use heavy duty or rechargeable batteries.
Display screennot working	Check that the batteries are installed correctly.Batteries may need to be replaced.Verify you're within the measurable temperature range (-40.0°F to 99.0°F; -40.0°C to 37.2°C).
