USER’S MANUAL

INTRODUCTION

Congratulations on your purchase of the Multi-Channel In-Out Thermometer / Hygrometer (EMR812HGN) 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 extra-large multifunction 2-line LCD that shows recordings for indoor and outdoor temperatures, humidity, maximum and minimum recordings and trend indicators. The unit supports up to three 433MHz remote thermo-sensors or thermohygro sensors. A variety of additional sensors can be purchased separately.

In addition to monitoring maximum and minimum temperature and humidity readings, the unit also has an alarm that can be set to activate once readings exceed a given variance.

No wire installation is required between the main and remote units. As the EMR812HGN operates at 433MHz, it can be used in the U.S. and most places in Continental Europe.

BEFORE YOU BEGIN

To ensure proper functioning of the EMR812HGN follow this setup procedure.

For best operation:

1. Assign different channels to different remote units.

2. Insert batteries for remote units before doing so for the main unit (see instructions for battery installation).

3. Place the main unit as close as possible next 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 20 to 30 meters.

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 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-4 or “AAA” size alkaline 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.

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 (2) UM-3 or “AA” size alkaline batteries.

Follow these steps to install / replace batteries:

1. Slide open the battery compartment door.

2. Insert the batteries strictly according to the polarities shown therein.

3. Replace the battery compartment door.

Replace the batteries when the low-battery indicator of the indoors temperature lights up. (Repeat the steps described in section “BEFORE YOU BEGIN”)

If not disposed of properly, batteries can be harmful. Protect the environment by taking exhausted batteries ot authorized disposal stations.
