USER’S MANUAL
INTRODUCTION
Congratulations on your purchase of the EMR812 Multi-Channel
In-Out Thermometer with 433MHz cable free sensor.
The EMR812 is an easy-to-use, state-of-the-art thermometer. The basic package comes with a main unit, which is the temperature station, and a remote unit, the thermo sensor.
The main unit has extra-large read-outs for indoors temperature and for that collected and transmitted by the remote unit. The main unit can support up to three remote units.
The main unit is capable of monitoring temperature changes of remote sites. By setting the upper and lower temperature limits the alarm will activate when those limits are exceeded. Also, the maximum and minimum temperature of different sites can also be retrieved quickly.
No wire installation is required between the main and remote units.
As the EMR812 operates at 433MHz, it can be used in the U.S. and most places in Continental Europe.

BATTERY AND CHANNEL
INSTALLATION: REMOTE UNIT
The remote thermo-hygro sensor unit uses two (2) UM-3 or “AA” size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
2. Select the channel number on the [CHANNEL] slide switch.
3. Select the temperature display unit on the °C/°F slide switch.
BEFORE YOU BEGIN
For best operation,
1. Assign different channels to different remote units.
2. Insert batteries for remote units before doing so for the main unit.
3
3. Replace the battery compartment door.
4. Insert the batteries strictly according to the polarities shown therein.
5. Replace the battery compartment 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”)
Note that once a channel is assigned to a remote unit, you can only change it by removing the batteries or resetting the unit.
LOW BATTERY WARNING
Replace the batteries when the low-battery indicator of the indoor temperature display lights up. (Repeat the steps described in section "BEFORE YOU BEGIN")
Respectively, for a remote sensor unit, the low-battery icon will show when the channel is selected.
BATTERY INSTALLATION: MAIN UNIT
The main unit uses two UM3 or "AA" size alkaline batteries.
To install them,
1. Slide open the battery compartment door.
2. Insert the batteries strictly according to the polarities shown therein.
GETTING STARTED
Once batteries are in place for the remote units, they will start transmitting temperature readings at 30-second intervals.
The main unit will also start searching for signals for about a minute once batteries are installed. Upon successful reception, the individual channel temperatures will be displayed on the top line and the indoors temperature on the bottom line. The main unit will automatically update its readings at about 30-second intervals.
4
If no signals are received, blanks “ ” will be displayed and the kinetic wave icon will show “ ”. Press CHANNEL and MEM simultaneously to enforce another search for about 30 seconds.
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.
goes blank “ ”, press CHANNEL and MEM to enforce an immediate search. If this fails, check the following.
1. The remote unit of that channel is still in place.
2. The batteries of both the remote unit and main unit and replace as necessary.
Note : When the temperature falls befow freezing point, the batteries of outdoor units will freeze, lowering their voltage supply and the effective range.
3. The transmission is within range and the path is clear of obstacles and interference. Shorten the distance when necessary.
TEMPERATURE TREND
The temperature trend indicator on the screen shows the trend of readings collected at that particular remote site. Three trends, rising, steady and falling, will be shown.
HOW TO CHECK REMOTE AND
INDOORS TEMPERATURES
The indoors temperature is shown on the bottom line of the display.
As for the remote sites or channels, press CHANNEL to go from one channel to another. The kinetic wave display on the channel number indicates the reception of that particular channel is in good order.

HOW TO USE TEMPERATURE ALARMS
The temperature alarms allow you to set the upper and lower limits of readings for individual channels. The alarm will activate if a limit is exceeded. To set the alarm,
1. Select the channel to be set.
2. Press the HI/LO button for the upper (HI) or lower (LO) limit. An
“OFF” message will be displayed if the alarm for that limit is turned off.
3. Use the ADVANCE ( s ) button to set the upper or lower temperature.
If this is the first time you set the limits, the lower limit will start from
-50°C (-58°F) and the upper limit +70°C (158°F). Otherwise, the reading will start from the temperature last selected.
Each press on the button will increase the temperature by one degree.
Holding on the button will step up the increment by five.
4. Press TEMP AL ON/OFF button to switch on or off the Max./
Min. temperature alarm. The set limit will be displayed.
5. Press HI/LO button to set another limit or return to normal display. The respective HI, LO or both indicators will light up to signify the status of the alarm.
When an alarm activates, the display will switch to the respective channel with the display flashing. If undisturbed, it will alarm for one minute. Press any key to momentarily mute the alarm. It will alarm again if the temperature continues to exceed the set limit.
To disable an alarm altogether, select the channel and use TEMP
AL ON/OFF to turn it off.
If you have set the upper and lower temperatures for more than one
channel and the limits are exceeded, the alarm will activate with the display switching from one channel to another at five seconds intervals.
As for the remote unit, it comes with a wall-mount holder and a removable stand. Use either to hold the unit in place.
