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.
ZONE | TEMP | HUMIDITY |
| Any | >70% |
| | |
| 20 – 25 ° C | 40 – 70% |
| (68 - 77 ° F) | |
| Any | <40% |
| | |
This information is shown in the Humidity Area when the current measurement is displayed.
RF SIGNAL RECEPTION
The RF Signal Indicator shows the signal receiving status for the main unit.
The unit is in searching mode.
Transmission data are securely registered.
No signals.
SCAN FOR REMOTE SENSORS
To auto-scan between sensors, press and hold CHANNEL for 2 seconds. Each sensor's data will be displayed for 3 seconds. To end auto-scan, press any button.
SEARCH FOR SENSOR
To search for a sensor, press IN /
REMOTE.
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.

SETUP
Note: To ensure proper reception between the main unit and the remote sensor, follow these instructions carefully.
1.Place both units as close as possible to each other.
2.Remove the screws on the battery door of the remote unit.
3.Assign a different channel to each remote sensor by changing the channel switch in the battery compartment of the remote sensor. [FIG A]
4.Select the units of measurement for the temperature display on the °C/°F slide switch. [FIG B]
5.Install 2 alkaline batteries (UM-3 or "AA" size 1.5V) strictly according to the polarities shown. [FIG C]
6.Insert batteries or press the reset button of the main unit. Follow the instructions as set out in the User's manual.
7.Replace the battery compartment door and secure its screws.
8.Position the remote sensor and main unit within effective transmission range, which in usual circumstances, is 30 meters.
Note: The effective range may be limited by building materials and the position of either the main unit or remote sensors. Try various set-up arrangements for best result.
Though the sensor is weatherproof, and is meant for use outside, it should be placed away from direct sunlight, rain, or snow.
