Vaillant sensoROOM Pure eBUS Room Thermostat | VRT50/2 | ErP Class V

Description

The Vaillant sensoROOM pure is a straightforward wired digital room thermostat designed to give homeowners clear, reliable control over room temperature and domestic hot water. Using Vaillant’s eBUS communication protocol, it can help a compatible Vaillant boiler modulate its output through enhanced load compensation, supporting efficient heating operation.

With a familiar rotary dial, large digital display and simple two core low voltage connection, the VRT 50/2 is a practical choice for both new installations and boiler control upgrades. It is particularly suitable where a clean, easy to use thermostat is required, while remaining ready for optional smart control through the myVAILLANT connect gateway and myVAILLANT app.
