MULTI-CHANNEL IN-OUT CABLEFREE THERMO-HYGROMETER
MODEL: BHGR618 USERS MANUAL

INTRODUCTION

Congratulations on your purchase of the Multi-Channel In-Out Thermometer / Hygrometer (BHGR618) with a 433MHz cablefree thermo-hygro sensor. Enclosed with this package is one (1) main display unit and one (1) cable-free remote thermo-hygro sensor unit. The main unit has an LCD that shows recordings for indoor and outdoor temperatures, humidity, maximum and minimum recordings. The unit supports up to three 433MHz remote thermo-sensors or thermo-hygro sensors. No wire installation is required between the main and remote units. As the BHGR618 operates at 433MHz, it can be used in the U.S. and most places in Continental Europe.

Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned. Try various set-ups for best result.
Though the remote units are weather resistant, they should be placed away from direct sunlight, rain or snow.
BATTERY AND CHANNEL INSTALLATION: REMOTE UNIT
The remote thermo-hygro sensor unit uses two (2) UM-4 or AAA size alkaline batteries. Follow these steps to install / replace batteries: 1. Loosen the screw on the battery door. 2. Select the channel number on the CHANNEL slide switch. 3. Select the temperature display unit on the C/F slide switch. 4. Insert the batteries strictly according to the polarities shown therein. 5. Replace the battery door and secure its screws. Replace the batteries when the low-battery indicator of the particular channel lights up on the main unit. (Repeat the steps described in section (BEFORE YOU BEGIN)

BEFORE YOU BEGIN

To ensure proper functioning of the BHGR618 follow this setup procedure. For best operation: 1. Assign different channels to different remote units. 2. Insert batteries in remote units before doing so for the main unit (see instructions for battery installation). 3. Place the main unit as close as possible to the remote unit, reset the main unit after installing batteries. This will ensure easier synchronization between the transmission and reception of signals. 4. Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 65 to 100 feet. 2

BATTERY INSTALLATION: MAIN UNIT
The main unit uses two (2) UM-3 or AA size alkaline batteries. Follow these steps to install / replace batteries: 1. Remove the screw to open the battery door. 2. Insert the batteries strictly according to the polarities shown therein. 3. Select the temperature display unit on the C / F slide switch. 4. Replace the battery door and fasten the screw. Replace the batteries when the low-battery indicator of the indoor temperature lights up (Repeat the steps described in section "BEFORE YOU BEGIN")
Upper window Displays temperature data
selected. Optionally, press and hold IN/REMOTE for 2-seconds to enforce a search.
MAXIMUM AND MINIMUM TEMPERATURE AND HUMIDITY
The maximum and minimum recorded temperature and humidity readings will automatically be stored in the memory. To display the maximum and minimum display memory: 1. Select the channel to be checked. 2. Press [MEM/CLEAR] once to display the maximum reading and again the minimum reading. The respective indicators, MAX or MIN will be displayed.
If not disposed of properly, batteries can be harmful. Protect the environment by taking exhausted batteries to authorized disposal stations.
To clear the memory: Press and hold [MEM/CLEAR] for 2-seconds.

GETTING STARTED

Once batteries are placed in a given remote sensor unit, it will start transmitting information at 40-second intervals. Also, for approximately a 3-minute duration, the main unit will automatically search for signals once batteries are installed. Upon successful reception, the individual channel temperature reading will be displayed on the upper window and the respective humidity reading on the lower window. The main unit will automatically update its readings at about 40-second intervals. If no signals are received, blanks --- will be displayed and the RF signal indicator will not show. To force a signal search: Press and hold IN/REMOTE for 2-seconds to enforce a 3-minute search. This is useful in synchronizing the transmission and reception of the remote and main units. Repeat this step whenever you find discrepancies between the reading shown on the main unit and that on the respective remote unit.
If you press [MEM/CLEAR] now, the maximum and minimum reading will have the same values as the current ones until different readings are recorded.

NOTE ON C AND F

The unit of temperature display is selected on the C/F slide switch. Select C for Centigrade or F for Fahrenheit. Note that the remote temperature display on the main unit is dominated by the selection on the C/F slide switch of the main unit. Whatever the display units of the remote sensors are, they will be automatically converted to the chosen one of the main unit.

COMFORT LEVEL INDICATORS

The comfort level indicators COM, WET or DRY will tell you if the curent environment is comfortable, too wet or too dry. The comfort indicators will appear on the display of the main and remote units when the following conditions are satisfied:
HOW TO CHECK REMOTE AND INDOOR TEMPERATURES & HUMIDITIES
Display of readings from a remote sensor or the main unit is a one-step procedure. The remote sensor channel or the main unit display is indicated under the readings. To display indoor temperature & humidity : Press IN / REMOTE until "in" is displayed under the readings. To display remote temperature & humidity : Press CHANNEL until the appropriate remote sensor channel is displayed under the readings. If no readings are received from one particular channel for more than 15 minutes, blanks --- will be displayed until further readings are successfully searched. Check the remote sensor to ensure that it is secure and that the correct channel has been 3

HOW TO READ THE RF SIGNAL INDICATOR
The RF signal indicator shows the signal-receiving status of the main unit. There are three possible forms:
The unit is in searching mode. Transmission data are securely registered. No signals.

LOW BATTERY WARNING

When it is time to replace batteries, the respective low-battery indicator will show up when the respective channel is selected. The battery level of the main unit will be shown on the indoor temperature when it is running low.

THE RESET BUTTON

To clear user-defined setting or if the unit is operating in an unfavorable way or malfunctioning use a blunt stylus to hold down the RESET button. All settings will return to the factory set defaults.

REMOTE SENSOR SCANNING

The unit can be set to automatically scan and display readings from the remote sensors. When the remote-sensor mode is active, the display will show the readings from one channel for about 4second and then proceed to the next channel display. To activate the remote-sensor scanning mode: Press and hold CHANNEL for 2-seconds.
TABLE STANDING OR WALL MOUNTING
Table-Standing : Your unit comes with stand connector for connecting it to other modular units.

To deactivate the remote-sensor scanning mode: Press any button.

STAND CONNECTOR

DISCONNECTED SIGNALS
If without obvious reasons the display for a particular channel goes blank, press[IN/REMOTE] to enforce an immediate search. If that fails, check: 1. The remote unit of that channel is still in place. 2. The batteries of both the remote unit and main unit. Replace as necessary. Note that when the temperature falls below freezing point, the batteries of outdoor units will freeze, lowering their voltage supply and the effective range. 3. The transmission is within range and path is clear of obstacles and interference. Shorten the distance when necessary. Connector:

TRANSMISSION COLLISION

Signals from other household devices, such as door bells, home security systems and entry controls, may interfere with those of this product and cause temporarily reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of readings will resume once the interference recedes.
Use wall-mount connector to align with other wall-mount bracket if necessary.
