2. Setup and Installation

2.1. Battery Insertion

The HR25-Energy requires two AA batteries (not included). Ensure correct polarity when inserting the batteries into the compartment, typically located on the back or side of the unit.

2.2. Mounting the Radiator Controller

The HR25-Energy is designed for easy installation on most standard radiator valves. It is compatible with M30 x 1.5 threaded valves. Adapters are provided for Danfoss RA, RAV, and RAVL valves.

1. Prepare the Valve: Ensure your existing thermostatic radiator valve head is removed. If you have a manual valve, it may need to be replaced with a thermostatic valve body.
2. Select Adapter (if necessary): If your radiator valve is not M30 x 1.5, identify the correct adapter from the supplied kit. The kit typically includes adapters for Danfoss RA, RAV, and RAVL valves.
3. Attach Adapter: Securely attach the appropriate adapter to your radiator valve.
4. Mount the Controller: Screw the HR25-Energy controller onto the valve or adapter until it is hand-tight. Do not overtighten.

3. Operating Instructions

3.1. Basic Operation Modes

The HR25-Energy offers several operating modes, accessible via the control buttons:

• AUTO Mode: The controller follows the programmed time schedule.
• ECO Mode: Activates an energy-saving temperature setting, typically lower than comfort temperature.
• MANU Mode: Allows manual temperature adjustment, overriding the programmed schedule.

3.2. Setting the Temperature

In MANU mode, or to temporarily override AUTO mode, use the adjustment dial (if present) or dedicated up/down buttons to set your desired temperature. The current temperature setting will be displayed.

3.3. Programming a Time Schedule

The HR25-Energy allows for a personalized time schedule with up to six switching times per weekday. Refer to the on-screen prompts and the 'PROG' button for detailed programming steps. This typically involves setting specific temperatures for different time blocks throughout the day.

3.4. Special Functions

• Optimization Function: Learns the heating characteristics of the room to achieve the desired temperature at the programmed time.
• Frost Protection: Automatically opens the valve if the room temperature drops below a set minimum (e.g., 5°C) to prevent pipes from freezing.
• Valve Protection: Periodically exercises the valve to prevent seizing.
• Child Lock: Prevents accidental or unauthorized changes to settings. Consult the device menu for activation and deactivation.

4. Maintenance

4.1. Battery Replacement

When the battery indicator appears on the display, replace the two AA batteries promptly. Use high-quality alkaline batteries for optimal performance and longevity. Ensure the device is in a neutral mode (e.g., MANU) before replacing batteries to avoid losing complex programming.

4.2. Cleaning

Clean the exterior of the controller with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the display or internal components.

5. Troubleshooting

If you encounter issues with your HR25-Energy controller, consider the following:

• Display Errors: If an error code appears, consult the full product manual (available from Honeywell Home support) for specific meanings. Often, removing and reinserting batteries can resolve minor display glitches.
• No Heating/Overheating:
  • Check battery level.
  • Ensure the controller is securely mounted on the valve.
  • Verify the operating mode (AUTO, ECO, MANU) and programmed temperature settings.
  • Confirm the valve pin is not stuck.
• Noise During Operation: A slight mechanical noise during valve adjustment is normal. Excessive or unusual noise may indicate a valve issue or improper mounting.
• Inaccurate Temperature Reading: Ensure the controller is not exposed to direct sunlight, drafts, or heat sources (like lamps) that could affect its internal temperature sensor.

For persistent issues, contact Honeywell Home customer support.
