2.3 Wiring
This is a wired thermostat. It switches with 230 V AC or can be used with potential-free systems. It is compatible with a switching load of 8 A capacitive and 2 A inductive. Refer to the wiring diagram on the back of the unit or consult a professional for proper connection to your heating or cooling system.

2.4 Battery Installation
The thermostat is powered by two 1.5V AAA batteries. Insert the batteries into the compartment located on the back of the unit, ensuring correct polarity (+/-).
3. Operating Instructions
The thermostat is designed for simple and direct temperature control.
3.1 Setting the Temperature
To adjust the desired temperature, rotate the large adjusting wheel on the right side of the thermostat. The LCD display will show the 'SET' temperature as you turn the dial. The 'ROOM' temperature indicates the current ambient temperature. The thermostat will automatically activate your heating or cooling system to reach the set temperature.

3.2 Display Backlight
The LCD display features a backlight for improved visibility, especially in low-light conditions. The backlight typically activates when the adjusting wheel is turned or a button is pressed, and then turns off after a short period of inactivity to conserve battery life.
3.3 Frost Protection
The thermostat includes a frost protection feature. If the room temperature drops below a certain threshold (usually around 50C), the thermostat will automatically activate the heating system to prevent pipes from freezing, even if the set temperature is lower.
3.4 Temperature Calibration
For precise temperature readings, the thermostat allows for calibration. This feature ensures that the displayed room temperature accurately reflects the actual temperature in your space. Refer to the full product manual or consult a technician for calibration procedures.
4. Maintenance
The EMOS Digital Room Thermostat requires minimal maintenance.
4.1 Cleaning
Clean the thermostat's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the plastic casing or electronic components.
4.2 Battery Replacement
When the battery indicator appears on the display, or if the display becomes dim, it is time to replace the batteries. Open the battery compartment on the back of the unit, remove the old AAA batteries, and insert new ones, observing correct polarity. Dispose of used batteries responsibly.
5. Troubleshooting
If you encounter issues with your thermostat, try the following basic troubleshooting steps:
- No Display / Dim Display: Check or replace the AAA batteries. Ensure they are inserted with correct polarity.
- Thermostat Not Responding: Ensure batteries are fresh and correctly installed. If the issue persists, a professional check of the wiring may be necessary.
- Incorrect Temperature Reading: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources. If the reading is consistently off, the unit may require calibration (refer to section 3.4 or consult a technician).
- Heating/Cooling System Not Activating: Verify the set temperature is appropriately higher (for heating) or lower (for cooling) than the room temperature. Check the system's power supply and circuit breaker. For persistent issues, professional electrical inspection is recommended.
For complex issues or if the problem persists after attempting these steps, it is advisable to contact a qualified technician or EMOS customer support.
