User Manual –Monitoring Swimming Pool Water Temperature
1. Brief Description
The swimming pool water temperature monitoring system consists of a large size
LED numerical display, RF floating water temperature sensor and IR remote con-
trol. This system measures and displays the water temperature in large format.
The measured temperature value is transferred into display from the floating sensor
placed into swimming pool some distance from display via wireless radio transmis-
sion.
LED display is based on super-bright 7-segment LED modules, AlInGaP chip tech-
nology, which ensures their good displaying properties in indoor environment with
artificial lights and long lifetime. Nevertheless, it is not advised to install this type of
display under direct sunlight. Display’s digit height is 10 cm and its viewing angle is
very large, up to 120°.
Mechanical design of display’s enclosure makes it suitable to be used in swimming
pool indoor environment. It is made of aesthetic platinum color anodized aluminum
and high quality dim front glass with anti-reflective surface. Back panel is from steel,
painted with black powder paint. Flexible power cable for connecting to electrical
installation junction box is attached to back panel of display. Installation junction
box is offered as optional accessory. If desired, serial RS485 line can be also pro-
vided from back side of display. It can be used for connecting display to a PC and
logging the measured values in a PC database. It is offered as optional accessory
together with data logging software application.
2. Display Features
Control of different parameters via IR remote control.
Measured values can be displayed in °C or °F. (Requires change of unit label.)
Brightness level can be set manually by user, or automatic brightness control
can be set in dependence of ambient light conditions.
Flashing of displayed value when preset high/low limits are exceeded.
Fixed correction offset of the measured value can be set in range from ±0,1° to
±9,9°C. (Although it is not normally advised as sensor is already calibrated in
factory.)
3. Display Control
The function buttons F1, F2, F3, F4 on the IR remote control are used to call the
menu items of different parameters of display. Aim the IR remote control toward
front side of display and press one of the function buttons F1 –F4 according to
desired parameter which you want to change.

Once in the function menu, use the Upp arrow / Down arrow to select item to
change and confirm your selection with OK button (located in the middle of arrows).
F1 OFS Correction offset. Using the up/down arrow set the value of desired
offset correction for the measured values. Default factory setting is
0,0°C. (Not normally used as the sensor is already calibrated.)
tU Temperature units. Select °C or °F. (Can require label change as
well.)
F2 CoL LED color setting. (Feature used in color LED displays only.)
Select desired color by holding button „up arrow“ / „down arrow“,
to change color and confirm with OK button.
F3 Lou Sets the lower limit. When this limit is exceeded:
Value on display will be blinking when blinking function is ON.
UPP Sets the upper limit. When this limit is exceeded:
Value on display will be blinking when blinking function is ON.
bOL Blinking (flashing) of display ON / OFF. Sets the blinking of display
after exceeding the upper or lower limit. Select oFF or on.
F4 CHA Sets the channel number of RF transmission with the floating sensor.
Floating sensor has ability to transmit on 3 different channels 1, 2, 3.
The CHA setting in display must match with the channel setting in
the sensor. Channel number in the sensor can be changed with the
switch inside the sensor. Factory default setting is “1”. To change the
channel number use the „up arrow“ / „down arrow“ keys.
Different channel numbers can be used in case there are more swim-
ming pools with floating sensors. Each display can be paired with one
corresponding floating sensor using its transmitting channel number.
Mod This feature allows two different Modes of display operation.
Aut –automatic, display receives the measured temperature data
from floating sensor.
MAn –manual, temperature value is entered manually via IR remote
control with the „up arrow“ / „down arrow“ keys. This feature can
be used without floating sensor, in case the user measures the water
temperature by other means (e.g. analogue thermometer) and enters
the value manually. Please note in Manual mode the displayed value
after power off / on will be set to preset value of 27°C.

2. Insert two AA alkaline long life batteries and close the battery cover, as
shown below.
3. Verify the rubber gasket is properly seated in the guide on transmitter
cover. Twist on the transmitter cover (clockwise), as shown below.
Channel Selection
RF transmitter can be set to transmit measured values on 1 of 3 channels. The
channel number must match with display’s channel number setting.
To change the transmitting channel number, twist off top cover and locate the blue
button marked “CH” from the inside. Press this button and the channel will change
between 1, 2, 3. You will see the selected channel number on the small LCD screen
(top left corner).
Setting Temperature Units °C or °F
To change the units, twist off top cover and locate the blue button marked “C/F”
from the inside. Press this button and the units will change between °C and °F. You
