Designed to work seamlessly with a range of heating products, the VRC 700/4 controller can manage central heating, domestic hot water, heat pumps and underfloor heating systems from a single interface.

Its weather compensation function continually monitors outdoor conditions and adjusts system performance accordingly, helping to maintain comfort levels efficiently throughout the year. When paired with the myVAILLANT app, users can control their heating remotely, set schedules and monitor energy consumption from virtually anywhere.

The high-contrast display provides excellent readability, while flexible programming options allow heating schedules to be tailored over either 24-hour or 7-day periods.

Flue Features

The supplied vertical air/flue duct and terminal are designed to safely discharge combustion gases through the roof, making them ideal where a horizontal flue arrangement is unsuitable. Manufactured from corrosion-resistant materials, the flue is built to withstand the elements and provide long-lasting performance.
