The Hour digit in the time section starts flashing Using the “MIN/MAX” key, enter the hours of the current time and then followed by pressing the “SET/CH” key to advance to the minute mode Again, using the “MIN/MAX” key, enter the minutes of the current time (by holding the key down, the digits are incremented in steps of five) and then finally followed by pressing the “SET/CH” key to exit the setting mode. Your Temperature Station is now fully operational.
USING THE TEMPERATURE STATION: INDOOR TEMPERATURE: The indoor temperature is displayed on the second line of the LCD under the time. The Temperature Station’s built in sensor automatically measures the temperature once the batteries are inserted.
MINIMUM AND MAXIMUM INDOOR TEMPERATURE RECORDINGS: Indoor sign Maximum icon Minimum icon 57
By pressing the “MIN/MAX” key the current indoor temperature will alternate between the minimum, maximum and current temperature recordings (also changes for outdoor temperature). Once a new indoor temperature high or low is reached, it will automatically set into the Temperature Station’s memory. OUTDOOR TEMPERATURE READING: The outdoor temperature reading is on the bottom line of the LCD under the indoor temperature.
Note: Should the outdoor temperature not be received within 2-1/2 minutes after inserting the batteries into a transmitter, then see “Checking 433 MHz reception” below.
MINIMUM AND MAXIMUM OUTDOOR TEMPERATURE READING: Outdoor sign Minimum icon Maximum icon 60
By pressing the “MIN/MAX” key the current indoor and outdoor temperature will alternate between the minimum, maximum and current temperature recordings. The time when the minimum and maximum outdoor temperature records were received will be also shown on the LCD blinking (recorded time is for outdoor temperature only). Once a new outdoor temperature high or is low reached, it will automatically be set into the Temperature Station’s memory.
RESETTING THE MINIMUM AND MAXIMUM TEMPERATURE RECORDING: By pressing and holding down the “MIN/MAX” key for about 3 seconds, both the indoor and outdoor minimum and maximum temperature recordings will be reset to the current indoor and outdoor temperatures. Only the outdoor temperature channel being displayed on the LCD will be reset. To reset another outdoor temperature channel, user shall first move to the desired transmitter No.
temperature readings of transmitter 1, 2, and 3, simply press the “SET/CH” key. If the reading is from transmitter 1, then the identification numbers 1 will be displayed in the outdoor temperature section of the LCD. The same will apply to the next transmitter and so on. However, if only one transmitter is used, no identification number will be displayed on the LCD.
1. 2. 3. 4. The distance of the units should be at least 1.5 - 2.0 meters away from interfering sources such as computer monitors or TV sets. Avoid placing the units onto or in the immediate proximity of metal doors, window frames or structures. Using other electrical products such as headphones and speakers that operate on the same signal (433 MHz) can prevent the transmission pick up. Neighbours using electrical products operating on the 433 MHz signal can also cause interference.
5. 6. reception is only possible once all other electrical products using the 433 MHz are switched off. Within thick concrete rooms such as basements and tower blocks, the 433 MHz signal can be weakened (avoid placing near metal frames and structures). Transmission can be affected by exposure to extreme temperature conditions. For example, if the weather has been extremely cold (under -25ºC) for an extended period of time then the transmission signal may be weakened.
Note: Should after checking the above list and the outdoor temperature is still not received, then reset the units (see Resetting the Temperature Station below). RESETTING THE TEMPERATURE STATION: 1. Remove the batteries from the Temperature Station and the transmitter(s) Wait at least 30 seconds and repeat the procedures specified in Setting up above.
POSITIONING TEMPERATURE STATION: The Temperature Station comes complete with a detachable stand that gives the option of table standing or wall mounting. To wall mount: 1. Fix a screw into the desired wall, leaving the head extended out the by about 5mm. 2. Using the Temperature Station’s hanging hole, carefully hang it onto the screw. Note: Always ensures that the unit locks onto the screw head before releasing.
OUTDOOR TRANSMITTER: The Outdoor Transmitter is supplied with a holder that may be attached to a wall with the three screws or double-sided tape supplied. To attach to the wall using screws, please follow the steps below: 1. 2. 3. Mark the wall using a pen through the holes in the holder to obtain the exact drilling position. Drill holes in the wall at the points marked. Screw holder onto wall.
The Outdoor Transmitter simply clicks in or out of the holder. When inserting or removing the Outdoor Transmitter to or from the wall holder please hold both units securely to avoid tearing the holder from the wall. There is also double sided tape included with the wall holder. On smooth surfaces this can be used instead of drilling holes. The mounting surface can, however, affect the transmission range.
securing in place, please ensure that the Temperature Station can receive the 433 MHz signal from the Outdoor Transmitter at the positions that you wish to situate them. CARE AND MAINTENANCE: • • Avoid placing the units in areas prone to vibration and shock as these may cause damage. Avoid areas where the units can be exposed to sudden changes in temperature, i.e.
• • • • When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or scouring agents. Do not submerge the units into water.
