3. Komponenti Overview
The Theben RAMSES 833 TOP2 HF Set 1 consists of two main components:
- Digital Room Thermostat: The user interface for setting and monitoring room temperature.
- Receiver Unit (Theben REC 1 868 MHz): The switching component that receives signals from the thermostat and controls the heating system.

The top part of the image displays the Theben RAMSES 833 TOP2 HF digital thermostat, featuring a backlit LCD screen showing 'RAUMTEMPERATUR' (room temperature) at 21.3°C, the current time 12:41, and mode indicators (MODE, PARTY, ECO, INFO). Below the screen are four control buttons. To the right is a rotary knob with red and blue segments for temperature adjustment. The bottom part of the image shows the Theben REC 1 868 MHz receiver unit, designed for DIN rail mounting. It has terminals for L (Live), N (Neutral), and output connections (7, 8, C1, 1, 2, 3). A series of LEDs (5, 4, 3, 2, 1) and a C1 button are visible, indicating its operational status and pairing function. The unit is marked 'Made in Germany' and 'CE'.
4. Setup
4.1 Receiver Unit Installation
The receiver unit (Theben REC 1 868 MHz) must be installed by a qualified electrician. It is designed for DIN rail mounting. Ensure the main power supply is disconnected before wiring.
- Connect the Live (L) and Neutral (N) wires to the corresponding terminals on the receiver. The unit operates at 230 V / 50-60 Hz.
- Connect the heating system control wires to the output terminals (e.g., 7, 8, C1, 1, 2, 3) as per your heating system's requirements and the wiring diagram provided with the product.
4.2 Pożizzjonament tat-Termostat
Place the digital room thermostat in a central location within the room, away from direct sunlight, drafts, or heat sources (e.g., radiators, lamps) that could affect its temperature readings. Ensure it is within the effective range of the receiver unit for reliable radio communication.
4.3 Initial Pairing and Settings
After installing the receiver and powering on both units, the thermostat and receiver need to be paired. Refer to the specific pairing instructions provided with your product, which typically involves pressing a pairing button on the receiver (e.g., the 'C1' button) and initiating a pairing sequence on the thermostat (often indicated by the wireless symbol on the display).
Once paired, set the current time and date on the thermostat if prompted. This is crucial for accurate program scheduling.
5. Istruzzjonijiet Operattivi
5.1 Aġġustament tat-Temperatura
The desired room temperature can be quickly adjusted using the rotary knob on the thermostat. Turning the knob clockwise typically increases the set temperature, while turning it counter-clockwise decreases it. The current room temperature and the setpoint will be displayed on the LCD screen.
5.2 Nifhmu l-Wiri
The LCD display provides key information:
- RAUMTEMPERATUR: Jindika t-temperatura attwali tal-kamra.
- Time (e.g., 12:41): Juri l-ħin kurrenti.
- Mode Indicators (MODE, PARTY, ECO, INFO): Show the currently active operating mode or provide access to specific functions.
5.3 Għażla tal-Modalità
Use the buttons below the display to select different operating modes:
- MODALITÀ: Typically used to cycle through main operating modes (e.g., Automatic, Manual, Off) or to enter programming menus.
- PARTIJIET: Activates a temporary comfort temperature setting, overriding the current program for a set duration.
- EKO: Engages an energy-saving setback temperature, ideal for periods of absence or overnight.
- INFORMAZZJONI: Provides additional information, such as current program status, battery level, or error codes.
5.4 Skedi ta' Programmazzjoni
The system supports up to 24 programmable timelines per program, allowing for precise control over your heating schedule. You can assign 3 comfort temperatures and 2 setback temperatures to different phases throughout the day or week.
- Access the programming menu via the MODE button or a dedicated programming button (refer to your specific model's detailed instructions).
- Define time blocks for each day.
- Assign a desired comfort or setback temperature to each time block.
- Save your program settings.
6. Manutenzjoni
6.1 Battery Replacement (Thermostat)
The digital room thermostat is typically battery-powered. When the battery level is low, a low battery indicator will appear on the display. Replace the batteries promptly to ensure continuous operation. Use the recommended battery type as specified in the product documentation.
