2. Safety Information
Before installation or operation, please read and understand all safety instructions. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Ensure power is disconnected before performing any installation, wiring, or maintenance.
- Installation should only be performed by qualified personnel in accordance with all local and national electrical codes.
- Do not expose the thermostat to moisture or extreme temperatures outside its specified operating range.
- Verify correct voltage and current ratings before connecting the device.
- Use appropriate personal protective equipment (PPE) during installation.
3. Installation and Setup
The Rittal 3110.000 thermostat is designed for easy mounting and wiring within an enclosure.
3.1 Mounting
The thermostat can be mounted on a 35 mm DIN rail (EN 60715) or fixed with screws. Ensure adequate air circulation around the device for accurate temperature sensing.
- Select a mounting location within the enclosure that is representative of the overall internal temperature and away from direct heat sources or cooling vents.
- For DIN rail mounting: Snap the thermostat onto the DIN rail until it clicks into place.
- For screw mounting: Use appropriate screws to secure the thermostat through its designated mounting holes.
3.2 Wiring
The thermostat features a terminal strip with external screw connections for simplified wiring. Refer to the wiring diagram below and the labels on the device for correct connections.

Connection Terminals:
- Terminals 1-2 (N, 48V/60V): Power supply for DC applications.
- Terminals 3-4 (Heating Symbol): Normally Closed (NC) contact for connecting heating elements. This contact opens when the set temperature is reached.
- Terminals 5-6 (Cooling Symbol): Normally Open (NO) contact for connecting cooling elements (e.g., fans). This contact closes when the set temperature is exceeded.
- Terminals 6-7 (L, 250V/110V): Power supply for AC applications.
Ensure all connections are secure and properly insulated. Double-check wiring against the specific application requirements before applying power.
4. Operating Instructions
The Rittal 3110.000 thermostat is simple to operate, primarily involving setting the desired temperature.
4.1 Setting the Temperature
The thermostat features a rotary dial on its front face for temperature adjustment. The dial is marked in degrees Celsius (°C).

- Locate the black rotary dial on the front of the thermostat.
- Rotate the dial clockwise or counter-clockwise to align the white indicator arrow with your desired temperature setting.
- For heating applications, the heating element will activate when the enclosure temperature falls below the set point and deactivate when it rises above.
- For cooling applications, the cooling element will activate when the enclosure temperature rises above the set point and deactivate when it falls below.
The thermostat's internal sensor will continuously monitor the enclosure temperature and switch the connected heating or cooling device on or off to maintain the set temperature.
5. Maintenance
The Rittal 3110.000 thermostat is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can ensure optimal performance.
- Cleaning: Periodically clean the exterior of the thermostat with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Connections: Annually inspect all electrical connections to ensure they remain tight and free from corrosion.
- Airflow: Ensure that the air vents on the thermostat are not obstructed, as this can affect temperature sensing accuracy.
- Calibration: The thermostat is factory-calibrated and generally does not require re-calibration. If you suspect a significant deviation in temperature readings, consult a qualified technician.
Warning: Always disconnect power to the enclosure before performing any maintenance.
6. Troubleshooting
This section provides solutions to common issues you might encounter with your Rittal 3110.000 thermostat.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power supply; incorrect wiring; blown fuse/breaker. | Check power source. Verify wiring connections (refer to Section 3.2). Check and reset circuit breaker or replace fuse. |
| Heating/Cooling element not activating. | Incorrect temperature setting; faulty wiring to element; element malfunction; thermostat malfunction. | Adjust temperature setting. Verify wiring to heating/cooling element. Test the element independently. If issues persist, consult support. |
| Inaccurate temperature control. | Obstructed airflow to sensor; thermostat mounted in non-representative location; faulty sensor. | Ensure clear airflow around the thermostat. Relocate thermostat if necessary to a more central area. If suspected faulty sensor, contact support. |
| Thermostat clicks but element doesn't activate. | Relay operating but no power to element; element wiring issue. | Check power supply to the element. Inspect wiring between thermostat output and element. |
If you are unable to resolve an issue using the troubleshooting guide, please contact Rittal customer support.
