## Summary description

Vaillant VR 90/3 is a remote room temperature controller featuring an integrated room temperature sensor and a weekly timer. Designed for controlling heating systems, it enables scheduled temperature changes and remote setpoint adjustment.

## Long description

Vaillant VR 90/3 is a room temperature remote controller with an integrated room sensor and a built-in weekly timer. Designed for controlling heating systems, the unit allows users to set temperature setpoints remotely and schedule temperature changes across the week. The controller is intended for installation in residential or small commercial environments where precise room sensing and timed temperature management are required.
Advantages
The VR 90/3 combines a room temperature sensor and a weekly timer in one compact device, reducing the need for separate components. Its remote control capability simplifies daily adjustments of heating setpoints without accessing the boiler or central unit. The weekly timer provides program-based temperature changes, supporting energy-efficient operation by automating lower setpoints during unoccupied periods and higher setpoints when comfort is needed.
Suitable for
 Control of residential heating systems with room sensing
 Small commercial or office installations requiring scheduled temperature changes
 Retrofit projects where remote adjustment and weekly programming are needed
 Applications where a wall-mounted room controller with an integrated sensor is preferred
When it may not be suitable
This controller is focused on room temperature control and weekly scheduling; it may not be suitable where advanced multi-zone management, complex HVAC integration, or remote cloud connectivity is required. If system control requires features such as weather compensation, multiple independent zone control within the same installation, or direct integration into certain building automation protocols, a different controller may be needed.
Key specifications
 Functionality: Room temperature control with integrated sensor and weekly timer
 User interface: Remote setpoint adjustment (wall-mounted remote controller)
 Scheduling: Built-in weekly programming for automatic setpoint changes
 Application: Residential and small commercial heating systems
 Mounting: Wall-mounted room controller
How to use
Install the VR 90/3 on an interior wall in a representative location away from direct sunlight, drafts, or heat sources to ensure accurate room sensing. Configure the weekly timer to define occupied and unoccupied periods and set the corresponding temperature setpoints for each period. Use the remote control interface to make temporary adjustments or override scheduled programs as needed. Follow the manufacturer's installation and wiring instructions to connect the controller safely to the heating system.
What to consider before purchase
 Verify compatibility with your heating system and boiler control interface
 Confirm that a single-room controller with integrated sensor meets your zoning needs
 Consider whether weekly programming is sufficient or if more advanced scheduling or networked control is required
 Plan installation location to avoid inaccurate temperature readings from local heat sources or drafts
Usage recommendations
Use the weekly timer to reduce setpoints during predictable unoccupied periods and raise them shortly before occupancy to balance comfort and energy use. Place the unit centrally in the controlled room at typical ambient height for reliable temperature measurement and occasional manual overrides to accommodate short-term comfort needs.
