BEFORE YOU BEGIN

To ensure proper setup, please note the following before you start:

Assign different channels to different remote units.

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

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.

Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 65 to 100 feet.

NOTE Refer to the REMOTE SENSOR section for sensor setup instructions.

BATTERIES

The Thermo Hygrometer uses 2 UM-3 ("AA") alkaline batteries.

1.Remove the screw to open the battery door.

2.Insert the batteries strictly according to the polarities.

3.Select the temperature display unit on the °C /°F slide switch.

4.Replace the battery door and fasten the screw.

5.Replace the batteries when the low- battery indicator of the indoor temperature lights up (Repeat the steps described in "Before You Begin", above)

shows when batteries are low for the main unit or for the selected remote unit.

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 show and the RF signal indicator will not show.

SEARCH FOR A SENSOR SIGNAL

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.

DISPLAY TEMPERATURE / HUMIDITY

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.

INDOOR UNIT

Press IN/REMOTE until "in" is displayed under the readings.

REMOTE SENSOR

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 t is secure and that the correct channel has been selected. Optionally, press and hold IN/REMOTE for 2-seconds to enforce a search.

MAXIMUM / MINIMUM TEMPERATURE / HUMIDITY

The maximum and minimum recorded temperature and humidity readings will automatically be stored in the memory.

DISPLAY MAXIMUM / MINIMUM MEMORY

1.Select the channel to be checked.

2.Press MEM / CLEAR once to display the maximum reading and again to display the minimum reading. The respective indicators, MAX or MIN will show.

CLEAR MEMORY

Press and hold MEM / CLEAR for 2-seconds. The current temperature and humidity will be saved as the min / max values until new records are set.

TEMPERATURE DISPLAY

Slide the °C/°F switch into the desired position to select °C (Centigrade) or °F (Fahrenheit) degrees display. The switch is located on the bottom of the unit.

NOTE The switch on the main unit over- rides any selection you may make for the remote sensor (THGR238N).

COMFORT ZONE

The Comfort Zone indicates how comfortable the climate is, based on current temperature and humidity measurements.

NOTE If the sensor is still not found, check the batteries, obstructions, and remote unit location.

NOTE Signals from household devices such as doorbells, electronic garage doors, and home security systems may cause temporary reception failure. This is normal and does not affect general product performance. The reception will resume once the interference ends.

NOTE Batteryperformance,andsubsequently the effective range, may be affected by freezing temperatures.
