indicates in 3 ways.
The weather is expected to be better.
Remain unchanged. The weather is expected to be worse.
As with any weather forecast, 100% accuracy cannot be guaranteed. This Thermo Hygro Station’s weather
forecasting feature estimated to have an accuracy level of 75% due to the varying climate it has been
designed for use in. In climates that experience sudden changes in weather (for example from sunny to
rainy), the Thermo Hygro Station will be more accurate compared to use in a climate where there is very little
change (for example almost always sunny).
Temperature Alert
This device can be programmed to alert that the temperature has risen or below a pre-determined range at the
receiving unit or any of the 3 remote sensors locations.
a. Press “ALERT” button to enable or disable temperature alert. Press & hold “ALERT” button for 2 seconds
to start setting.
b. The “ ” upper/lower icon will blink. Using the “+” or “-” button to select Indoor, Channel 1, 2 or 3 (if 3
sensors are available). Press “ALERT” button to confirm.

Press “ALERT” to confirm.
d. The “ ” lower limit icon will blink. Using “+” or “-” button to enter lower limit value, and press “ALERT”
button to confirm.
e. To set alert values for other registered channel, select the desired channel and repeat the same procedure
from (a to d).
When the “ ” upper/lower icon appear, all alarms previously set for each channel including indoor temperature
channel will become active. When the alert ranges are reached or passed, alarm will sound and the upper/lower
icon will flash.
Display T1, T2 or Autoscroll
Press the “(T1/T2)” button to select T1, T2 or autoscroll between the two modes.
Installation of Remote Sensor(s)
Locating remote sensor in clear open area can attain a maximum 30-meter transmission distance. Actual
transmission distance can be reduced by interference from building, obstruction or a screen between the
remote sensor(s) and the receiving unit. The remote sensor(s) have been designed to accommodate a variety
of mounting options. The remote sensor(s) can be hang on a flat wall by means of a wood screw. You can also
use the stand when you desired a horizontal surface mount.
To Activate Backlight

Battery Replacement
A “
” low battery icon will appear on the display of the receiving unit. when the batteries of the receiving unit
and remote sensor(s) need to be replaced. For replacing batteries always use new batteries as specified in the
user’s manual. Do not mix old and new batteries as the old ones may leak.
Troubleshooting for losing Signals
If without obvious reasons the display for particular channel suddenly goes (---) dash, check:
• The remote unit of that channel is still in place.
• The batteries of both receiving and remote unit. Replace as necessary.
• The transmission is within range and path is clear of obstacles and interference. Shorten the distance when
necessary
• Signals from other household devices, such as bell, home security system and entry controls, it may
interfere with those of this product and cause temporarily reception failure. This is normal and it doesn’t
affect the general performance of the product. The transmission and reception of temperature reading
readings will resume once the interference recedes.
Precautions
a. Do not clean the units with abrasive or corrosive compound. It may scratch the plastic parts and corrode
the electronic circuits.
b. Do not subject the unit to excessive force shock, dust, temperature or humidity, which may result in
malfunctioning, shorter electronic life span, damage batteries and distorted parts.
c. Do not tamper with these units’ internal components. Doing so will invalidate the warranty on the unit
and may cause unnecessary damage battery and distorted parts.
d. Do not subject the units to excessive exposure to direct sunlight. Although remote sensor has splash proof
design. Never immerse it in water or expose to heavy rain.
