The Vaillant VWZ AI Heat Pump Appliance Interface is an indoor control module designed to connect compatible Vaillant aroTHERM plus and aroTHERM Pro air source heat pumps with the property's heating system.
Providing a central point for system information and temperature settings, the VWZ AI allows users to access heating flow and domestic hot water temperature controls. Its semi-touch display also provides useful information about system operation, including environmental energy yield, operating hours, heating circuit pressure and fault messages.
Heating and Hot Water Control
The VWZ AI provides access to key heating system settings, including heating flow and domestic hot water temperatures. When installed as part of a compatible Vaillant heating system, it works alongside the relevant controls and accessories to manage system operation.
Clear System Information
The integrated semi-touch display provides access to important system information, helping homeowners and heating engineers monitor operation and identify potential issues.
Displayed information includes:
Daily environmental energy yield
Total operating hours
Building circuit filling pressure
System status information
Fault messages and diagnostic information
Built-in CIM Adapter
The Vaillant VWZ AI features an integrated Customer Integration Module (CIM) adapter, allowing a compatible myVAILLANT connect internet gateway or wireless receiver to be connected.
The connected accessory can draw its power directly from the interface, removing the need for a separate power supply for the compatible device.
Compatible Vaillant Heating Controls
The VWZ AI can work alongside compatible Vaillant system controllers, including sensoCOMFORT. Depending on the wider system configuration and installed accessories, this can support timed control across multiple heating zones.
Compatibility should be checked against the specific heat pump, controller and system configuration before ordering.
