FAQs

Do I need the evohome controller to use these radiator thermostats?

Yes, the Honeywell Home HR924UK radiator controllers require a Honeywell Home evohome Smart WiFi Thermostat controller to function. They cannot operate as standalone thermostats.

How long do the batteries last?

Each HR92UK unit has an estimated battery life of two years under normal usage conditions. A low battery reminder will appear on the screen when it's time to replace them.

Can I install these myself?

Yes, installation is designed to be straightforward. They typically screw onto existing TRV bodies. Adapters for Danfoss RA series valves are included. If you are unsure, professional installation is recommended.

What happens if I open a window?

The 'Open Window' feature detects a rapid drop in room temperature and automatically shuts off the radiator to save energy. The radiator will resume normal operation once the room temperature stabilizes.

Can I control these thermostats using a smartphone app?

Yes, when the HR92UK controllers are paired with an evohome Smart WiFi Thermostat controller that is connected to WiFi, you can control and schedule your heating remotely via the Honeywell Home app.

How accurate is the temperature control?

The HR92UK offers precise room temperature control, accurate to within 0.5°C, contributing to consistent comfort levels and energy efficiency.

What is the warranty period for this product?

Honeywell Home offers a 5-year guarantee on the HR92 Radiator Controllers.

Can I use these with any radiator valve?

They are designed to fit most standard TRV (Thermostatic Radiator Valve) bodies and include adapters for Danfoss RA series valves. It's advisable to check your existing valve type if you have non-standard fittings.

Troubleshooting

Radiator not heating or not turning off

Ensure the HR92UK is correctly paired with the evohome controller. Check that the valve inside the TRV body is not seized; manually operate the valve pin to ensure it moves freely. Verify the heating schedule and setpoint temperature are appropriate.

HR92UK not communicating with evohome controller

Check battery levels in the HR92UK. Ensure the HR92UK is within range of the evohome controller or any installed signal boosters. Try re-pairing the device to the evohome controller following the setup instructions.

Display is blank or unreadable

Replace the batteries with fresh ones. Ensure the screen is clean and not obstructed. Adjust the screen angle if necessary.

Open Window feature not working

Confirm the 'Open Window' feature is enabled in the settings via the evohome controller. Ensure the room temperature drop is significant enough and rapid enough to trigger the sensor. Clean any vents on the HR92UK unit.

Low battery warning persists after replacing batteries

Ensure the batteries are inserted correctly and are of the specified type (AA Alkaline). Try a different set of batteries. If the issue persists, contact customer support.

Setup, Compatibility & Care

Setup:

  1. Installation: The HR92UK controllers are designed to fit most standard TRV (Thermostatic Radiator Valve) bodies. If your existing radiator valves are compatible, you can usually screw the HR92UK directly onto them. Adapters for Danfoss RA series valves are included.
  2. Pairing: Once installed, each HR92UK controller needs to be paired with your Honeywell Home evohome Smart WiFi Thermostat controller. Follow the guided setup process on the evohome controller, which typically involves putting the controller into pairing mode and then activating the HR92UK unit.
  3. Configuration: After pairing, you can name each zone (e.g., 'Living Room', 'Master Bedroom') and configure its specific heating schedule via the evohome controller or the associated mobile app.

Compatibility:

  • Evohome System: These controllers are specifically designed to work with the Honeywell Home evohome Smart WiFi Thermostat controller.
  • Radiator Valves: Compatible with most standard TRV bodies and includes adapters for Danfoss RA series valves.
  • Power: Each unit requires 2x AA Alkaline batteries, which are included in the kit.

Care:

  • Cleaning: Clean the exterior of the HR92UK with a soft, dry or slightly damp cloth. Avoid using abrasive cleaners or solvents.
  • Battery Replacement: Replace batteries when the low battery indicator appears on the screen (typically every two years). Use high-quality alkaline batteries.
  • Winterization: Ensure the frost protection setting is enabled if the system will be unused during cold weather to prevent pipe freezing.
