What does Error 12 mean on a Vasco electric radiator thermostat?

How can I check if my Vasco E-Volve WiFi module is connected to the temperature sensor?

To verify the connection between your E-Volve WiFi module and temperature sensor, open the Vasco Climate Control app and navigate to Settings, then Setup, then E-Volve WiFi. Select your room and open Room Settings to check the sensor connection status. If the sensor is not detected, ensure it has fresh batteries and is positioned within Bluetooth range of the WiFi module.

Why is the boost function not working on my Vasco electric radiator?

The boost function may not work if the thermostat is not connected to the blower unit, open window detection is enabled, the target temperature has been reached, or the radiator lacks power. Check these factors and disable open window detection if needed. You can also activate boost directly on the blower unit.

Why is my Vasco radiator only partially warm after installation?

A Vasco radiator that only partially warms after installation may have the supply and return pipes connected the wrong way round. This is a common installation issue. Contact a qualified heating engineer to check and reconnect the pipes correctly if reversed.

What does a blinking green LED mean on a Vasco E-Volve controller?

A blinking green LED on a Vasco E-Volve controller indicates frost protection mode is active or open window detection has been triggered. Close any open windows or doors and the radiator will resume normal operation once the temperature stabilises.

Do I still need to place radiators under windows?

In older, poorly insulated homes, placing radiators under windows remains advisable to combat cold draughts from single or poor-quality glazing. However, in well-insulated homes built within the last 20 years, radiators can be positioned anywhere due to improved glazing and insulation.

Why is my Vasco radiator cold at the top but warm at the bottom?

This is typically caused by air trapped in the radiator, preventing hot water from circulating fully. Bleeding the radiator using a radiator key or screwdriver at the bleed valve will release the trapped air and restore proper heating.

What is the difference between the Vasco Boost and Boost H ventilation systems?

The standard Vasco Boost recovers heat from exhaust air to warm incoming fresh air. The Boost H includes an enthalpy heat exchanger that recovers both heat and moisture from the outgoing air, providing improved indoor comfort during the heating season by maintaining better humidity levels.

How do I control a Vasco electric radiator with WiFi?

The E-Volve WiFi module connects your electric radiator to your home WiFi network, enabling control via the Vasco Climate Control app. The module communicates via Bluetooth with a temperature sensor placed in the same room, allowing you to set temperatures individually for each room from anywhere.

What is the ideal temperature for Vasco underfloor heating?

Set underfloor heating surface temperatures differently for each room based on use. Bathrooms are typically most comfortable with floor surface temperatures around 32°C, while living areas work well at around 28°C. These are floor surface settings, not room air temperatures. There is no single perfect temperature—adjust based on personal comfort.
