5.1 Mounting the Thermostat
- Identify a suitable location on the pipe where temperature sensing is required. Ensure the surface is clean and free from obstructions.
- Position the thermostat against the pipe.
- Wrap the provided helical spring around the pipe and secure it to the thermostat's mounting points. Ensure the thermostat is held firmly against the pipe for accurate temperature transfer.
- Alternatively, use the wall mounting hardware to fix the thermostat to a flat surface if pipe mounting is not applicable or a remote sensor (if purchased separately) is used.

5.2 Electrical Wiring
The EMOS P5683 is a wired thermostat operating at 230 Volts. Refer to the wiring diagram provided inside the device's terminal cover for specific connections. It is crucial to follow all local electrical codes.
- Ensure the main power supply is disconnected before commencing any wiring.
- Connect the power supply (230V) to the designated terminals.
- Connect the heating or cooling system's control wires to the appropriate output terminals.
- Double-check all connections for tightness and correct polarity.
- Once wiring is complete, replace the terminal cover securely.
6. Operating Instructions
This section details how to operate your EMOS P5683 thermostat for optimal temperature control.
6.1 Powering On/Off
- To turn the thermostat ON, press the Power button. The digital display will illuminate.
- To turn the thermostat OFF, press and hold the Power button for a few seconds until the display turns off.
6.2 Setting the Target Temperature
The temperature can be set between 5°C and 80°C in 0.1°C increments.
- With the thermostat powered on, the display shows the current temperature.
- Press the Up (▲) or Down (▼) button to enter temperature setting mode. The set temperature will flash.
- Use the Up (▲) or Down (▼) buttons to adjust the desired target temperature.
- After a few seconds of inactivity, the thermostat will automatically save the new setting and return to displaying the current temperature.
6.3 Adjusting Switching Sensitivity (Hysteresis)
The switching sensitivity (hysteresis) determines the temperature difference between the set point and the actual temperature at which the heating/cooling system will activate or deactivate. It can be adjusted from 0.1°C to 15°C.
- Consult the detailed instructions in the full manual for accessing the sensitivity setting menu, as this typically involves a combination of button presses.
- Once in the sensitivity setting mode, use the Up (▲) or Down (▼) buttons to select the desired sensitivity value.
- Confirm the setting or wait for it to save automatically.
6.4 Special Features
- Frost Protection: This feature automatically activates the heating system if the temperature drops below a preset minimum (e.g., 5°C) to prevent freezing. Refer to the full manual for activation and adjustment.
- Holiday Mode: Allows you to set a lower, energy-saving temperature for an extended period when you are away. Consult the full manual for setup.
7. Maintenance
Regular maintenance ensures the longevity and accurate operation of your thermostat.
- Cleaning: Wipe the thermostat's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
- Inspection: Periodically check the wiring connections for any signs of wear or looseness. Ensure the helical spring maintains firm contact with the pipe.
- Environment: Keep the thermostat free from excessive dust and ensure it is not exposed to direct sunlight or heat sources that could affect its temperature readings.
8. Troubleshooting
If you encounter issues with your EMOS P5683 thermostat, try the following steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; Device is off | Check power connections and circuit breaker. Press the Power button to turn on. |
| Incorrect temperature reading | Poor contact with pipe; External heat source | Ensure the helical spring holds the thermostat firmly against the pipe. Relocate if exposed to direct heat/cold. |
| Heating/Cooling system not responding | Wiring error; System malfunction; Set temperature not reached | Verify wiring connections. Check the heating/cooling system's power. Adjust set temperature to trigger operation. |
| Buttons unresponsive | Temporary software glitch | Turn the thermostat off and then on again. If problem persists, disconnect power for 5 minutes and reconnect. |
