VariPro WiFi Room Controller

Informative for End Users

The VariPro WiFi room controller for fan coil units features a clear and user-friendly interface that makes room temperature adjustment simple. The controller displays both the current room temperature and the newly set target value—key parameters from the user’s perspective. The screen also shows the direction the HVAC system is adjusting the temperature, and the estimated time it will take to reach the target value. The display is customizable to suit specific applications.

By default, fan speed is automatically controlled based on the set temperature. If desired, fan speed can also be manually adjusted in three steps, in which case the automatic fan speed control is bypassed.

Control via Mobile App

The VariPro mobile app allows users to control, schedule, and monitor the operation of the fan coil units.

The VariPro mobile app is available for download in the Google Play Store and the Apple App Store.

Useful for Service and Maintenance

The VariPro WiFi room controller provides extensive individual data and diagnostics about the status and operation of the connected unit(s). The controller monitors, for example, the cooling energy consumption of the fan coil unit and gives predictive maintenance alerts. All data can be accessed either directly from the controller or via the building automation system (BAS). This information supports both preventive and reactive maintenance strategies.

Interface for Building and Room Management Systems

The setpoint and fan speed of the fan coil unit can be controlled either from the building automation system or from the room controller, depending on the needs of the application. For example, in hotel settings, occupancy detection activated by a key card can be communicated via the Modbus connection to the building or room automation system, which can then adjust the default setpoint based on occupancy information.

Quick Installation and Commissioning

With its streamlined design and compact dimensions, the VariPro WiFi room controller is suitable for both recessed and surface wall mounting. It comes with a quick-connect cable that enables fast and easy connection to the fan coil units. The preconfigured connection also helps prevent wiring errors. The VariPro WiFi controller’s ”Start-Up Wizard” automatically configures the controller based on the connected devices, saving valuable time during installation.

A single room controller can control multiple fan coil units located in the same room.

Connection Options

The VariPro control system can be integrated into building automation systems via a data-based Modbus connection. The terminal unit control system can be connected either to the wall-mounted controller or directly to the building automation system. The room controller can also be managed through the BMS, enabling control of one or multiple terminal units in the room.
