FEATURE
The thermostat you have purchased is programmable type, which simply means it has a
built in clock and can change it's temperature settings automatically throughout the day. This
may be confusing at a glance, but there are some very good reasons why this may be
desirable.
For example, let's say you live in an area where it is cold outside, and you have your heating
system running to heat up the inside temperature to 21ºC . This is comfortable temperature in
the house when you're sitting around with your family, but it uses a lot of electricity or gas to
maintain that temperature all day, when you are at work a good part of that day.
With a programmable thermostat you can set the temperature back, perhaps to 16ºC while
you are away at work, and to 18ºC at night while you are sleeping and still have it set to a
comfortable level during the times that you are relaxing at home.
An efficient heat system should "kick on", or cycle, four to six times an hour while
maintainging one set temperature. However, if the temperature has been set back to a lower
level or set up to a higher level, the unit will have to run much longer to recover to the comfort
level.
The big question here is, how many degrees can you set the temperature back to keep the
heat from cycling on when you don't need it, and still be able to bring the temperature back up
to your comfort level without the heating unit having to run excessively? Many factors will
affect this balance: How big is the difference between outside and inside temperatures? How
big is your house? How efficient is your heating unit? How well insulated is your house?
How many and what hours are you away from home? How many and what hours do you sleep?
The pre-programmed set of times and temperatures within your new thermostat can be altered
to better match your needs if you so desire. Be sure to also read the section on the next few
page for more information on determining the best settings for your situation.

APPLICATION
This thermostat can be used for "Floor Heating System". This device should be installed and
serviced by a qualified technician, and make sure that power has been disconnected before
installation.
The floor sensor cable should be installed to the terminal block No. 1 and No.2 (The floor
sensor cable is an optional accessory).
When installation is correctly done, set the thermostat on the base, then reset the thermostat
by pressing the "Reset" button, the thermostat will automatically check if the floor sesor is
installed and read the room temperature.
Note: It is not necessary to have the floor sensor installed when fitting with a non-floor heating
system.
Atte tio !
If the floor sensor cable is not installed, floor temperature detecting function will not be able to
use. Whenever the cable is installed, reset the thermostat by pressing the "Reset" button. This
will activate the floor temperature detecting function immediately.
There are two operation modes can be selected:
1. Room temperature mode.
The thermostat will ignore the reading from floor sensor. In this mode, the temperature of the
room will determine whether the heating system is activated.
2. Floor temperature mode.
In this mode, the thermostat will continuously compare the floor and room temperatures to the
preset temperature setting. When these temperatures are reached, then the thermostat will
automatically turn off the heating system.
Now the thermostat you have purchased is floor heating control type, which simply means it
has a built in floor temperature set and can change it's temperature setting.
You have two choices to set floor heating control mode
a) If the user selects FL: mode, the unit will control the N/ FF of the HEATNG via air
sensor, it will not concern the detection of floor sensor.
b) If the user selects FL: A mode, the unit will control the N/ FF of HEATING via both of
floor and air sensor. Here the setting range of floor sensor is 10ºC ~ 45ºC .
There are two conditions to turn on the heating:
●Floor temperature is lower than the floor sensor setting
●Air Temperature is lower than the air sensor setting
(In any of this conditions is fulfilled, the thermostat will turn on the heating)
There are two conditions to turn off the heating:
●Floor temperature is higher than floor sensor setting.

EUROSTER 3000 – USER MANUAL 6
●Air temperature is higher than air sensor setting.
(Either one of a.m. condition will turn off the heating immediately)

THE DIFFERENTIAL
The differential is the term given to the amount the thermostat will allow the temperature to
vary from the Set Temperature. This feature allows you to decide how closely the thermostat
will control the temperature in the room. The less time the unit runs, the less
money you spend on utilities!
Your new thermostat comes to you preset to allow the room temperature to climb 1 above the
Set Temperature, and then will let it fall 0.5ºC below the Set Temp. This has been found to be

EUROSTER 3000 – USER MANUAL 9
a balance between energy savings and comfort for most average people.
For example: It's winter, the heating unit is running and has just brought the room
temperature up to 21ºC. You have your new thermostat set to 21ºC and have not altered the
preset differential. The heating unit will continue running until the room temperature reaches
21.5ºC before turning off. The temperature wil then beging to fall, and will continue falling
until the heating unit turns back on when the room temperature falls to 20.5ºC .
In this example you have a differential of 1ºC of the Set Temp.
Let's say you set your thermostat at 21ºC . You set the Differential setting to 0.5ºC . Your
room's temperature would be allowed to vary from 20.75ºC~21.25ºC. Differential is adjustable
and can be set at 0.5ºC or 1ºC .
Which settings will work best in your home, controlling your heating units, can best be
determined by simple experimentation.
To review and N T CHANGE the differential just press and hold for more than 3 seconds  
buttons. The display should change to show the differential setting. Press to return to
normal operation (the unit automatically returns if no key is pressed for 10 secs).
T CHANGE the differential press and hold for more than 3 seconds  buttons press . The
display should change to show the differential setting.
Use the NEXT button select 0.5 or 1.0 of differential
When you are satisfied with your settings press  to return to normal operation (automatic if
no key is pressed for 10 seconds).
MANUAL OPERATION MODE
By simply pressing the H LD button you can place your new thermostat into a manual
operation mode, where you set the desired temperature and it is maintained. The Hold
indicat r will appear on the display confirming that you have entered Hold mode.

EUROSTER 3000 – USER MANUAL 10
The  and  buttons are used to adjust the temperature. If no key is pressed
for 10 seconds the Thermostat will change into H LD M DE and display the
current temperature. At any time you can return to the Program controlled
mode by pressing H LD or .
This Manual mode is more desirable in some cases. You may feel more
comfortable with a conventional thermostat.
r, you may have experimented with different programmed times and
temperatures, and discovered that you are not achieving the level of savings
or comfort that you had hoped for. This may be due to the amount of
insulation in your home, or a heating that may have too slow recovery rate to
allow for setting the temperature back or forward. Your lifestyle or job may
have your home occupied so much of the time that it is simplay impractical to have the
temperature vary at different times. It may also be that you find that you are not maintaining
the level of comfort that you are used to from a constant temperature.
Regardless of the reasons, your new thermostat can still provide you with years of service, while
providing you with many features not available in conventional thermostats.
FEATURE MANUAL MODE / VACATION HOLD
You can use MANUAL M DE/VACAT N H LD to set up the desired temperature while you are
on vacation. Thus the energy usage of your heating system can be lowered well by using this
function.

TEMPORARY OVERRIDE
A Temporary verride has been provided to allow you to temporarily change the temperature
without altering the thermostat's program. The thermostat will use the new temperature
setting during the duration of this program period. At the start of the next program period, the
override will be cancelled and the thermostat will return to the temperatures stored within the
program.
To activate the override all you need to do is adjust the temperature using the  and 
buttons.
The verride indicator will light up just beside the set temperature (Temp Set). In approx. 10
seconds the thermostat will begin to run temporary override mode. The Rotary Time Display
shows the desired time under Temporary verride mode. (The present time will start
flashing. )
If the time remaining until the next program period is not practical for your needs, such as,
you have friends over and the house is getting too warm, you can overide the temperature to
lower it. The display shows the override will only last for an hour and two minutes.
Your company may be staying loger than an hour or two. You would be better off using
