5. Installation

5.1. Mounting the Thermostat

The thermostat is designed for wall mounting. Choose a location away from direct sunlight, drafts, and heat sources for accurate temperature readings.

1. Carefully separate the front panel from the back plate of the thermostat.
2. Position the back plate on the wall at the desired height.
3. Mark the drilling points through the mounting holes on the back plate.
4. Drill holes (typically 5mm diameter) at the marked points and insert the provided wall plugs.
5. Secure the back plate to the wall using the provided screws.

5.2. Wiring Connection

This thermostat is compatible with 2-wire heating systems (e.g., gas, diesel, pellet boilers). It connects to the COM (Common) and NO (Normally Open) terminals of your heating system. Maximum current capacity is 5A.

Image: Detailed wiring diagram. NC (Normally Closed contact), COM (Common terminal), and NO (Normally Open contact) are labeled. The heating connection uses COM and NO.

1. IMPORTANT: Ensure power to your heating system is OFF before proceeding.
2. Connect the two wires from your heating system to the COM and NO terminals on the thermostat's back plate.
3. If your system supports cooling, you would typically use COM and NC (Normally Closed) terminals, but this thermostat is primarily designed for heating applications.
4. Once wiring is complete, carefully reattach the front panel of the thermostat to the back plate.

5.3. Battery Installation

The thermostat requires 2 AA batteries for operation.

6.2. Adjusting Temperature

When the thermostat is on, rotate the knob to adjust the desired SET temperature. The display will show the new set temperature. The thermostat will automatically activate the heating system if the room temperature falls below the set temperature.

6.3. Display Information

The backlit LCD screen continuously displays the current room temperature, the set temperature, and the current time. A flame icon indicates when the heating system is active.

7. Programming

The thermostat offers programmable features to manage comfort and economy temperatures throughout the day. It includes 3 programs: 2 fixed and 1 configurable.

7.1. Setting Time and Day

Before programming, ensure the current time and day are correctly set. Refer to the specific instructions in your full manual for detailed steps on setting the clock.

7.2. Fixed Programs

7.3. Configurable Program (Hour by Hour)

The configurable program allows you to set specific comfort or economy temperatures for each hour of the day, adapting to your personal schedule.

1. Access the programming mode (refer to your full manual for button sequences).
2. Select the configurable program option.
3. For each hour, use the rotary knob to select either 'Comfort' or 'Economy' temperature.
4. Confirm each hour's setting.
5. Save the program settings.

Note: Detailed instructions for entering programming mode, setting specific temperatures for comfort/economy, and saving programs are found in the comprehensive manual provided with the product.

8. Maintenance

• Cleaning: Wipe the thermostat with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display. Always replace both AA batteries simultaneously.
