EBERLE UTE 4800 Series Programmable Thermostats
Product Overview
The EBERLE UTE 4800 series offers programmable thermostats designed for efficient heating and cooling control. The series includes models UTE 4800-R, UTE 4800-F, and UTE 4800-Rw, each featuring a large, clear display and user-friendly interface.
Visual Description of Products:
Three digital thermostat units are depicted. Each unit features a prominent display showing "21.0 °C" for the current temperature and "AUTO" mode. Below the temperature, "14:31" indicates the current time. The interface includes navigation buttons labeled "Menü", "EBERLE", "Info", "+", and "OK". The models shown are:
- UTE 4800-Rw (50 x 50 mm)
- UTE 4800-R/UTE 4800-Rw
- UTE 4800-F
Characteristics
- Supply Voltage: AC 230V
- Backlight: White, activated upon key press.
- Display: Very large, single-line text display for self-explanatory operation.
- Programs: Preset and adjustable lifestyle time programs, with an extra day program option (e.g., for holidays).
- Switching Time Blocks: Supports 7-day, 5/2-day, or all-day scheduling configurations.
- Optimum Start: Ensures the target temperature is reached precisely at the set time.
- Party Timer: Allows for temporary, hour-specific temperature adjustments.
- Valve Adaptation: Compatible with normally open valves (specifically for R/Rw variants).
- Valve Protection: Features valve protection (R variant).
- Seasonal Changeover: Automatic switching between summer and winter time.
- Daily Events: Supports a maximum of 9 switching events per day.
- Access Protection: Prevents unauthorized access or changes.
- Holiday Mode: Enables setting a specific date range for vacation periods.
- Frost Protection: Integrated frost protection function.
- Control Modes: Operates using PWM or 2-point (ON/OFF) control methods.
- Remote Operation: Programmable even when the control panel is detached.
- Energy Consumption Display: Provides insights into energy usage by showing heating on-time and associated costs for the last 2 days, week, month, or year (primarily applicable to electric heating systems).

Wiring Diagram
The wiring diagram illustrates the connections for the thermostat. It shows terminals for AC power input (N for Neutral, L for Live) and a sensor connection. Output terminals are also indicated. The diagram is labeled as an example for the 4800-Rw model.
Diagram Description:
The diagram shows a simplified representation of the thermostat's internal connections. It includes:
- Power Input: Terminals labeled 'N' (Neutral) and 'L' (Live) for AC 230V, 50 Hz power supply.
- Sensor Input: A terminal labeled 'Sensor' for connecting an external temperature sensor.
- Output Terminals: Terminals labeled 'N', 'L', and 'C' are shown, likely representing connections for the controlled heating/cooling system.
