This programmable thermostat has been designed to be used with fixed oil, gas or electric heating systems, and may be used in place of most indoor home thermostats.

WARNING The thermostat should be installed only in dry, indoor areas, in fixed heating systems, and on non-conduc- tive surfaces. To avoid electrical shock, always disconnect the heat- ing system from the main electrical power from the70 English

English master switch in the house. Please read carefully the following instructions before installing the thermostat. Where to Install the thermostat The ideal location for your thermostat is a spot approximately 1’5 meters from the floor, in a well ventilated area, and far from: 1.Indoor draughts 2.Heat sources 3.Heat from the sun or household appliances 4.Built-in pipes or chimneys It is advisable to install your thermostat in a frequently used room, such as the living room or dining room. Mounting the thermostat on the wall Remember to disconnect the main electrical power from the central swtich before taking out the old ther- mostat and installing the new one.

1. Before placing the batteries, make a hole in the

wall, making sure that the thermostat cable termi- nals are properly aligned.

2. Next, place one of the plastic anchors provided with

the thermostat into the hole. Make sure the anchor is flush with the wall.

3. Fit one of the screws provided into the anchor.70

4. On the back of the thermostat, there is a hole on

the right side. With the back of the thermostat facing the wall, line up the hole on the thermostat with the screw on the wall, moving the thermostat toward the left until it fits into the guide.

5. Open the front cover of thermostat. In the battery

compartment there is a second hole for mounting the thermostat. Mark on the wall the location for the second screw, making sure that it is in line with the first screw, and remove the thermostat.

6. Make a hole where you put your mark, and place

another plastic anchor, again ensuring that the plug is flush with the wall.

7. Mount the thermostat on the wall and connect the

cables to the terminals as shown in the following diagram. If you have any questions or concerns, call our customer service number.

8. The terminals are found on the back of the ther-

mostat. Only two cables are needed to connect the thermostat to the heater, these cables are shown in the heater electrical diagram or in the electrical diagram of the thermostat which is replacing. Note: When there is not previous installation, bear in mind that most heaters have their own thermostat. Remove the connecting bridge between the heater and its own thermostat, and connect the heater to the cables leading directly to the new thermostat.72 English

English For greater safety, however, consult the manual for your particular heating system beforehand.

9. Again line up the new thermostat with the hole

for the first screw. Open the front cover, and fit the screw into the plug located behind the battery compartment. 10.Once the thermostat is mounted and connected, procede to reconnect the main electrical power from the household main switch. Placing the Batteries The thermostat operates with two 1’5 V AA batteries, preferably alcaline. To switch on the thermostat place the batteries into the battery compartment. When inserting the batteries for the first time, the screen should show two different informations alter- natively: in the first screen it shows the time, date and room temperature (for example 22ºC), as shown in the drawing below:72 English

English In the second screen it shows the consignment tem- perature, as shown in the drawing below: If case the screen shows a different information, press the RESET key using a sharp object, such as a paper clip. After inserting the batteries, close the thermostat front cover. When the battery level is below the minimum to ensure the correct working of the thermostat, the screen will show the symbol . When this happens, replace the batteries for new ones, preferably alcaline.

4. CRONOTHERMOSTAT ADJUSTMENTS

The thermostat has serveral control functions which can be adjusted by the user: Temperature Differential Adjustment The temperature differential refers to the minimum temperature difference between room and consign- ment temperature which causes a working change. The temperature differential can be set between 0’2º C and 1º C. To set the temperature differential:

1. Press the DIF CL key until you see on the screen

2. With / keys set the temperature differen-

3. To set the new differential value and return to the

normal operating mode, press SET key. Temperature Gauge Adjustment In some special cases the thermostat can be installed in a place where it cannot measure the room tempera-74 English

English ture you wish to control. For example, you may wish to control the temperature in the dining room and the thermostat is located in another room, so we have to take into account that there might be a temperature difference between both rooms. To compensate this temperature difference between the two rooms, the temperature gauge can be modified between –5ºC and +5ºC, depending on the temperature difference existing between the two rooms.

1. Press and hold the DIF CL key until you see on the

2. With / keys set the temperature gauge.

3. To set the new differential value and return to the

normal operating mode, press SET key. This value will be used to add or subtract it from the real room temperature measurement shown in the screen, using this temperature as the control temperature.

5.CONTROL TEMPERATURE SETTING

This thermostat works according to two different con- trol temperatures: economic temperature, symbolized as a moon drawing in the screen, and comfort tem- perature which is symbolized as a sun drawing. Normally, “comfort” temperature is the one we want to have when we are at home and “economic” tempera-76 English

English ture when we are out. Obviously, “economic” tempera- ture should be lower than “comfort” temperature. For example, if the user does not change the pre-set control temperatures, will have a “comfort” tempera- ture of 21ºC and an “economic” temperature of 18ºC. During the periods in which it is selected the “com- fort” temperature, the system will keep the room temperature around 20ºC depending on the selected temperature differential. When the user selects the “economic” temperature, the system will be activated only if the room tempera- ture falls below 18ºC minus the differential. When the temperature comes again over 18ºC plus the differen- tial, the system will stop. In order to change both “economic” and “comfort” temperatures:

1. Press key, the sun indicator starts blinking.

2. With / keys set the “comfort” temperature.

5. Finally press the SET key to confirm and exit. If76

English you don´t press any key, it will exit automatically after 15 seconds also saving the new temperature values. The factory pre-set values are the following: -comfort temperature: 21ºC -economic temperature: 18ºC -control temperature for or HEAT mode: 7ºC. The unit will exit from this function automatically if any key is not pressed in 10 seconds.

Once you have set the control temperatures, time and date, you can set the working program. To do so, select the day or group of days in which you want the program to be activated, the number of program you want and if the program is not a pre-set one, set the temperatures we want for each period. SELECTION OF THE DAY/GROUP OF DAYS AND PROGRAM NUMBER
