[. . . ] Though the remote unit is weather proof, it should be placed away from direct sunlight, rain or snow. MAIN FEATURES: REMOTE UNIT MODEL THGR228N a Two-line LCD Displays the current temperature and humidity monitored by the remote unit LED indicator Flashes when the remote unit transmits a reading °C/°F slide switch Selects between Centigrade (°C) and Fahrenheit (°F) Channel slide switch Designates the remote unit Channel 1, Channel 2 or Channel 3 BATTERY AND CHANNEL INSTALLATION: REMOTE UNIT The remote thermo-hygro sensor unit uses two (2) UM-4 or "AAA" size alkaline batteries. Select the temperature display unit on the °C/°F slide switch. b c d 2 HOW TO SET THE CLOCK AND CALENDAR MANUALLY When the current time is displayed, press and hold MODE for three seconds. If 12-hour clock format is selected, the time will be displayed with the AM or PM indicator. Insert the batteries strictly according to the polarities shown therein. [. . . ] If the SNOOZE/LIGHT button is pressed, the SNOOZE function will be triggered. The alarm will stop and the bell icon blinks for about eight minutes before going off again. CHANNEL SCAN FUNCTION Press and hold CHANNEL button for 3 seconds to enter channel scan function. The readings of each channel will be displayed one by one for 4 seconds automatically. Press any key to stop the scan function. NOTE ON REMOTE TEMPERATURE & HUMIDITY Once batteries are in place for the remote unit, it will start transmitting samplings at 39-43-second intervals. If no signals are received when the remote temperature and humidity is selected, blanks will be displayed. This is useful in synchronizing the transmission and reception of the remote and main units. Make sure the transmission is within range and path is clear of obstacles and interference. Repeat this procedure whenever you find discrepancies between the reading shown on the main unit and the remote unit. PRE-ALARM FUNCTION FOR CHANNEL 1 REMOTE SENSOR The alarm function also has a pre-alarm feature which can alert the user before the preset alarm time when weather condition changes. Press and hold the ALARM button for 3 seconds to set the operating time interval for this pre-alarm function. Use the UP or DOWN button to select from the 4 timeintervals: 15, 30, 45 or 60 minutes. The pre-alarm function will be enabled automatically which is indicated by the appearance of the [ ] symbol. To disable this function, press the DOWN button in the Pre Alarm mode. The pre-alarm will operate during the selected time interval before the daily alarm time. For example, if the daily alarm is set to go off at 7:00 am and the pre-alarm operating time interval is set to 45 minutes, the pre-alarm will start to operate at 6:15 am (45 minutes before 7:00 am). During the pre-alarm operating period, if the temperature recorded at Channel 1 remote sensor falls to or below 2. 0ºC, the pre-alarm will be triggered. The Pre-Alarm icon will flash and the backlight will be turned on for 5 seconds. An alarm sound will also go off for 2 minutes as that of the daily alarm and the snooze function will also be activated if the SNOOZE/LIGHT button is pressed. Note: The daily alarm will NOT function until the next day if the pre-alarm has been triggered beforehand. Deactivation of the alarm function will disable the pre-alarm feature automatically. NOTE ON °C AND °F The outdoor temperature display on the main unit is dominated by the selection on the °C/°F slide switch of the main unit. Whatever the display unit of the remote sensor is, it will only apply to the remote sensor itself and the temperature will be automatically converted to the chosen one of the main unit. MAXIMUM AND MINIMUM TEMPERATURES The maximum and minimum recorded temperatures will be automatically stored in memory. To display them, press MEMORY to toggle among the maximum, minimum and current temperatures. If you press MEMORY now, the maximum and minimum temperatures and humidities will have the same values as the current one until different readings are recorded. TEMPERATURE AND HUMIDITY TREND HOW TO CHECK INDOOR AND OUTDOORREMOTE TEMPERATURES & HUMIDITIES To display indoor temperatures and humidities, press the CHANNEL button until the [ ] indicator lights up. [. . . ] Then adjust the angle of the display panel for best display and support. Proposed operating range Temperature resolution : -5. 0°C to +50. 0°C (23. 0°F to 122. 0°F) : 0. 1°C (0. 2°F) Remote Temperature measurement Proposed operating range Temperature resolution : -5. 0°C to +50. 0°C (23. 0°F to 122. 0°F) : 0. 1°C (0. 2°F) Relative Humidity Measurement Indoor relative humidity : 25% RH to 95% RH measurement range Resolution : 1% RH Remote unit HOW TO RESET THE UNIT The RESET button allows you to return all settings to its factory values. The button is required only when the unit is not operating in a favorable way, such as in the rare case of a malfunction. The RESET button is located at the back of the unit below the battery compartment. [. . . ]
