Established in 1997, Prefect Controls Ltd aimed to design and produce intuitive yet straightforward energy controls that met the commercial needs of building operators while offering fixed control access for occupants.
In 1997, Prefect focused on commercial sectors such as room providers, student accommodation, and hotels, where excessive heating energy use by guests—who did not directly bear the cost—was a significant issue.
We identified a clear market need for a range of controls that would allow guests to manage their own settings, while enabling business owners to maintain overall control of temperature and time settings behind the scenes. By addressing the needs of both guests and business owners, Prefect Design Engineers have developed a comprehensive range of space heating controls, from standalone (local) units to fully centralised systems. Throughout this process, our focus on the original brief—“Clever but simple”—has guided us from design through system installation and into end-user operation.
Our Products Include:
irus - Central Control
Prefect Irus is an award-winning building energy management system designed for multiple occupancy properties like university accommodations and hotels. It addresses the challenge of managing energy costs by providing precise control over heating and other environmental factors, preventing issues such as excessive heating when rooms are unoccupied or windows are open. With features like Mains Borne Signalling (MBS) for cost-effective installation, Irus allows easy setting and monitoring of temperatures and time profiles in each room. It also tracks humidity, CO2, light, and noise levels to ensure a comfortable living environment and can manage water heating to optimise energy savings and detect leaks. Unlike other systems, Irus offers unparalleled localised control, ensuring energy is used only when necessary.
ecoStat - Local Control
ecoStat integrates operational efficiency with guest comfort by allowing occupants to adjust the temperature within preset limits using the room’s intelligent thermostat. It features three modes: ‘Setback’ for normal occupancy, ‘Boost’ for higher temperatures on demand, and ‘Frost’ for extended vacancies. Compatible with electric panel heaters, wet radiator systems, and most boilers, ecoStat's robust construction make it well-suited for demanding environments like student accommodations. It also detects unoccupied rooms and open windows to adjust heating accordingly. ecoStat is 100% tamper-proof due to the dedicated infrared programming handset used to adjust individual room controls. One handset is required for each site and is only accessible to authorised personnel.
HobSensus - Kitchen Safety
HobSensus is an award-winning kitchen safety device tailored for student accommodations, communal kitchens, and assisted-living settings. It prevents overheating by cutting power to the hob before reaching fire flashpoint temperatures and automatically switches off after 30 minutes of inactivity. The device features a 64-zone temperature sensor and is compatible with most 600mm or 900mm electric hobs, offering a 40Amp switching capacity. It operates on hard-wired (LV) or battery power and integrates with the Prefect Irus Central Control system. Compliant with EN50615:2015, HobSensus is quick to install and easy to use.
