Fan Coil Controls & Valves

Fan coil unit (FCU) controls are systems of controls and valves that regulate a fan coil unit’s operation by controlling temperature, fan speed, and water flow through heating or cooling coils. They ensure efficient indoor climate control by responding to thermostat settings, occupancy, or building management systems' signals to meet and maintain desired space thermal and ventilation conditions.

What are the most common types of fan coil unit controls?

Here at Ability by Dimplex, we offer a comprehensive range of FCU control systems for both standalone and fully networked configurations. Controllers can manage individual units or integrate into a wider building management system (BMS) using BACnet protocol, alongside other HVAC and access systems.

Our control range includes advanced controller options like Delta Red5 (high performance, scalable, IoT-enabled) and Easy IO FW (WiFi-enabled, flexible for networked or standalone use). User interfaces vary from simple room controls to advanced touchscreens with built-in temperature and humidity sensors. We also supply a range of valves.

Control systems for all types of buildings

We can help deliver a controls strategy for a variety of building types that consolidate a wide selection of HVAC technologies, besides our fan coil units and chilled water cassettes. We can integrate with BMS systems and a range of controllers by either manufacturers or provide our own. Our goal is system functionality and specification flexibility.

Office, retail and commercial FCU controls

We offer flexible fan coil unit controls that integrate with existing or new BMS systems, enabling complete user visibility, responsive real-time control, smart settings, and design flexibility. Systems can be expanded across multiple floors or buildings without being restricted to a single manufacturer’s hardware.

Residential FCU controls

Our apartment control systems provide a single, central interface to manage heating, cooling, ventilation and hot water across a variety of emitters in each apartment. Residents can control settings via the ATMO app, allowing flexible management of temperature, fan speed, and schedules. The fan coil controls system can also connect to district heating systems and combine central efficiency with individual comfort control.

Hotel FCU controls

Hotel FCU controls by Ability range from simple standalone thermostats in individual rooms to fully networked large scale solutions for multiple HVAC technologies in the largest hotels worldwide. Applications vary from fan coil controls for smaller boutique hotels to large hotel chains that utilise bespoke BMS systems.

Control valves and commissioning

We supply and commission a full range of control valves to complement our fan coil unit control systems. These include pressure independent control valves (PICVs) and electronic pressure independent valves (ePIVs) to optimise the flow rates, reduce energy usage, and deliver reliable heating and cooling performance for all seasons.

Witness testing: Supporting the specification of fan coil controls

At Ability by Dimplex, we carry out comprehensive testing of our fan coil unit controls at a dedicated facility in our factory in Poole, Dorset. We also offer witness testing, providing clients with complete transparency and confidence in the testing process and results relevant to their project.

Using the client’s drawings, we replicate ductwork layouts, grille locations and other system elements in our testing laboratory. By matching the fan coil unit controls selection, the testing results enable specifiers and contractors to validate design choices, confirm compliance with project requirements and fine-tune the fan coil system design before on-site installation and commissioning.

FCU testing includes:

Acoustic testing: Confirms that sound levels meet specification, ensuring the acoustic performance of the installed fan coil units is as expected.
Volumetric performance testing: Verifies airflow, air resistance and pressure drops to streamline fan coil commissioning.
Thermal performance testing: Demonstrates heating and cooling outputs, fan coil performance and condensate management, ensuring the finished design delivers both comfort and efficiency.

All FCU testing is carried out using high-quality, regularly calibrated testing equipment. Once the fan coil controls testing is complete, clients receive a detailed report that includes test results, photographs, layout drawings and calibration certificates.

Benefits of Ability fan coil unit controls

Project specific – wide range of FCU control options enable delivery of smart solutions tailored to match each project's unique requirements.
Remote control – fan coil systems can be managed directly from the room or remotely via a local or cloud-based network for convenience of users.
Full technical support – all control systems are designed, commissioned and supported by our technical team, ensuring smooth integration and operational efficiency.
Commissioned for maximum performance - our commissioning service ensures each control package performs precisely as intended. Every system is tested, balanced and fine-tuned for maximum efficiency and comfort.
Accurate flow rate – the FloSet® Compact is a small, PICV preassembled valve set for heating and cooling applications. Its continuously self-adjusting feature ensures precise balanced delivery of required flow rate.
Waste reduction - The Belimo ePIV continuously measures flow and pressure to optimise water delivery, reduce energy waste and improve system stability.
Versatile - Ability designs, supplies and commissions a comprehensive range of fan coil unit control systems suitable for both standalone and networked configurations.
Usability with energy saving - Delta Red5 series controllers offer fast processing speeds and support a range of HVAC and control systems, enabling improved occupant experience while reducing energy use.
Connectivity - Easy IO FW series controllers are WiFi-enabled controllers so can be used as part of an existing network or as an isolated BMS solution.
Remote access management - We also offer cloud-based portfolio management, which provides remote access to monitor performance, adjust settings and diagnose issues across multiple sites.
Wide compatibility - Ability systems connect seamlessly across mixed-platform buildings via open-protocol BACnet and are compatible with Trend, Delta, EasyIO and other major systems.
Integration with hotel systems - integrate with booking platforms to automatically prepare rooms, offering fault monitoring, helping maintenance teams fix issues early to improve comfort, energy efficiency, and operational reliability.
