CABLE FREE THERMOMETER

MODEL: EMR812

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.

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. Initially place both units close together. This will ensure synchronization between the remote unit and the main unit. Then, install batteries for the main unit or reset the main unit.

4. Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 30 meters.

Note : Building materials and where the main and remote units are positioned can vastly affect effective range. Try various set-ups for best result.

Though the remote units are weather proof, 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-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.

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.

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.

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.

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.
