There is a sliding door on the right half of the thermostat. If you open the door, you

After opening the door, you can flip the door up or down to see the dip switch
and battery compartment.

Temperature mode
You can see ☼ and  on both the buttons and the LCD. ☼
means comfort temperature and  means economy tem-
perature. These two temperatures are user changeable.
Furthermore, there is a fixed defrost temperature (7°C)
indicated by  on the LCD. Throughout the operation of
the thermostat we will refer to them as comfort, economy
or defrost temperature instead of numeric values.
Program
Euro-thermostat is a programmable thermostat. It can automatically adjust the
room temperature to a comfortable level when you are at home, and lower it to
save energy when you go out or sleep. What you have to do is to program the
thermostat so that it knows when to raise the temperature. There are altogether
nine programs contained in the memory of the thermostat. Six of them are preset
in the factory and the remaining three are user changeable.
Manual override
If you want to change the temperature temporarily and do not want to alter the
programs you have set, you can simply touch a button to override the current
program.
INSTALLATION INSTRUCTIONS
Caution: Switch off the electric source before installing the thermostat. We re-
commend that the installation be performed by trained personnel.
Select a suitable location for the thermostat. The location of the thermostat can
greatly affect its performance. If it is located where air circulation cannot reach,
or exposed to direct sun light, it will not adjust the room temperature properly.
To ensure proper operation, the thermostat should be installed at an inside wall
with freely circulating air. Find a place where your family is usually occupied.
Avoid close proximity to heat generating appliances (e.g. TV, heater, refrigerator)
or exposed to direct sunlight. Do not install near a door where the thermostat
will suffer from vibration.
Wiring
Wiring terminals are at the back of the thermostat.
You can find three terminals labeled COM, NO and NC.
It is a typical single-pole, double throw (SPDT) contact.
In most situations COM and NO are used.
Mounting the thermostat
Using the template provided, drill two ø6mm holes in the wall. Insert the wall
anchors and tighten the left screw with 3mm clearance. Fix the thermostat by
putting it over the screwhead and slide it rightward (note the keyhole-like opening
at the back of the thermostat). Tighten the remain screw to lock it in place.
Note: If the wall is made of wood, there is no need to use the wall anchors. Drill
two ø2.7mm holes instead of ø6mm.
USING YOUR NEW THERMOSTAT
The following procedures show how to operate the thermostat. It is recommended
that you follow the instructions and try to operate once before connecting it to
the heating or cooling system.
1, Start
The thermostat is operated by two LR6 alkaline batteries. Please remove the
front cover and install two new batteries.
When the batteries are installed, the thermostat should be operating and you
can see the LCD active. If the thermostat does not work properly, please check
the batteries for wrong polarities and press the reset button by using a ball-point
pen.
The LCD after start or reset:
SUN MON TUE WED THU FRI SAT

Note:
i, Temperature may not be 20°C as the diagram shown and the Output-On in-
dicator may activate after a few seconds, depending on different situations.
ii, Do not use a pencil to push the reset button. The graphite residue of a pencil
can cause a short circuit and damage the thermostat.
2, Set day/time
To set day, press d. Similarly, press h to set hour and m to set minute.
Buttons used:
Example:
When start or after reset, the time is 00:00,
Sunday. To set the clock to current time (e.g.,
11:23, Tuesday), press d 2 times, h 11 times
and m 23 times.
Note: When you press and hold the keys for 2 seconds, the day/time will change
rapidly. Release when the desired setting comes.
3, View/Change temperature
Press Temp, and the thermostat enter View/Change temperature mode. The
LCD will show the setting of the current temperature mode (☼,  or ) which
will be flashing. Press ☼ or  to review or change the temperature. Press OK
to directly return to normal operation mode. Buttons used:

iv, Please note the temperature mode indicator. A ☼ means the comfort tempe-
rature is being viewed or changed. A  indicates economy temperature. If is
shown, it is defrost temperature. Defrost temperature is always at 7°C and is
not changeable.
