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.

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

A blinking red LED on a Vasco E-Volve controller indicates that boost mode is active, providing rapid heating to 30°C for one hour. The radiator will automatically exit boost mode after the set duration, or you can cancel it manually by pressing the boost button again.

What does the Er error mean on a Vasco electric radiator?

The Er error on a Vasco electric radiator indicates that the room temperature sensor is defective or disconnected. Switch off and unplug the radiator from the mains before any inspection. If the error persists, contact a qualified heating engineer for sensor replacement.

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

A blinking orange LED on a Vasco E-Volve controller indicates that manual override is active via the MEMO button. This temporarily overrides the programmed schedule. Press the MEMO button again to cancel the override.

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

Error 12 on a Vasco thermostat indicates a communication fault between the thermostat and radiator. Switch off and unplug the radiator from the mains. Remove the thermostat batteries, wait two minutes, then reinsert the batteries and restore power. The system should resynchronise automatically.

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.

How can I maximise heat output from my Vasco radiators?

Do not place furniture in front of radiators or hang heavy curtains over them, as this inhibits heat distribution. Avoid drying wet clothes or towels on radiators, as this captures the heat and prevents it spreading. Bleed radiators regularly and maintain the heating system properly.

What happens if the insert valve on a horizontal panel radiator is positioned incorrectly?

Horizontal panel radiators with bottom connections have integrated tubes designed to direct water flow in a specific pattern. If the insert valve is placed on the wrong side, water cannot circulate properly through the radiator, resulting in uneven heat distribution or the radiator not heating at all.

Are Vasco fan convectors suitable for low-temperature heating systems?

Yes, Vasco fan convectors work efficiently with low-temperature heating systems such as heat pumps. The fan enables effective heat distribution even when the water supply temperature is lower than in traditional systems, making them ideal for sustainable heating solutions.

What happens if the supply and return pipes are connected the wrong way round?

If the supply and return pipes are reversed, the radiator will not heat properly or may only warm partially. To identify the correct connections, increase the thermostat setting and feel which pipe heats up first—this is the supply (flow) pipe.
