5. Setup and Installation
The EMOS P5684 thermostat is designed for flexible installation. The remote sensor allows for accurate temperature measurement directly at the heat source, even in hard-to-reach locations.
5.1 Mounting the Thermostat
- Choose a suitable location for the thermostat unit, ensuring it is protected from direct sunlight, drafts, and heat sources that could affect its internal temperature.
- Secure the thermostat unit to a wall or surface using appropriate screws.
5.2 Connecting the Remote Sensor
The 0.9-meter remote sensor should be placed to accurately measure the temperature of the medium or area you wish to control (e.g., a pipe, water tank). Ensure the sensor is securely attached and insulated if necessary to prevent external temperature influences.
5.3 Electrical Wiring
WARNING: Electrical wiring must be performed by a qualified professional. Ensure power is OFF before wiring.
- Open the wiring cover on the thermostat unit.
- Connect the power supply (230V AC) to the designated terminals.
- Connect the heating or cooling appliance (e.g., pump, valve) to the output terminals.
- Ensure all connections are secure. Loose connections can lead to malfunction or safety hazards.
- Close the wiring cover securely.

6. Operating Instructions
The EMOS P5684 thermostat features a user-friendly interface for setting and monitoring temperatures.
6.1 Digital Display
The backlit digital display shows the current measured temperature. When adjusting settings, it will temporarily show the set temperature or parameter value.
6.2 Setting the Desired Temperature
- Press the 'Up' or 'Down' arrow buttons to enter temperature setting mode. The display will flash the current set temperature.
- Use the 'Up' or 'Down' arrow buttons to adjust the desired temperature. The temperature can be set between 5°C and 90°C in 0.1°C increments.
- After a few seconds of inactivity, the thermostat will automatically save the new setting and return to displaying the current measured temperature.
6.3 Adjusting Switching Sensitivity (Hysteresis)
The switching sensitivity (hysteresis) determines the temperature difference between the turn-on and turn-off points of the controlled appliance. This prevents rapid cycling of the appliance.
- Refer to the specific instructions provided with your thermostat for accessing the hysteresis setting. This typically involves a combination of button presses or a dedicated mode.
- Adjust the sensitivity between 0.1°C and 15°C using the 'Up' or 'Down' arrow buttons. A lower value means more precise control but more frequent switching; a higher value means less frequent switching but wider temperature fluctuations.
- Confirm the setting to save.
