Average installation time – 45 minutes per room

Home / Services





We believe that good installation is as important as good product design. Our elite team of Prefect-trained and qualified electrical engineers is experienced and efficient.

This crack team is equipped with the latest Prefect installation hardware allowing them to quickly install Irus, ecostat2 or Hobsafe with the minimum of disruption and mess.

Prefect Project Managers and Team Supervisors ensure site work is carried out to the highest standard and that all Health and Safety rules are adhered to.

Being familiar with the specialist equipment, the way systems operate, and product configuration means our installation service is very competitive.

More than 20 years of working in student accommodation and hotels has given us a unique insight into completing retrofit installations with minimal impact on a building’s infrastructure, or disruption to occupants of a room.

All our engineers are NIC EIC qualified electricians with years of experience in these unique environments and conditions. We routinely receive praise for the friendly and respectful way we conduct our installations.


Hobsafe is easy and quick to install. However, work must be carried out by a competent electrician. Hobsafe can be mounted in both surface and flush boxes. Time and program switches should be set before installation. Hobsafe is located between the isolation switch and the hob unit. We estimate 45 minutes for installation.


Installation of ecostat2 is straightforward for a competent electrician. However, they must ensure compliance and conform to relevant regulations in force at the time of installation. To provide accurate operation, ecostat2 units should be mounted 1200-1400mm from the finished floor level and a minimum of 300mm from the heat source. ecostat2 is connected to a panel heater (for electric systems) or the Thermal Drive Valve (for wet systems) via a Switched Fused Spur.


The installation of our Irus system is a specialist task and should only be considered by experienced electricians. Prior to any Irus installation we tender for, we will carry out a free, no-obligation survey from which we will identify any issues or abnormalities that need addressing. Following this we will provide a clear schedule of works and costings.


The survey will also provide details of the number of locations and type of equipment required. For example, control units, room heaters, water heating monitors, leak detection apparatus, and water sentinels. From this a bill of quantities will be generated.

A map of each location is created using the equipment type: building, floor, individual location (e.g. “Block A”, “Ground Floor”, “Flat 1”) this will make a unique identification number to assign a ‘unit serial number’ for when the site is commissioned.

The site is then added onto the web portal, where it is imported into the live system ready for the installation of the hardware and onsite commissioning.

Pre-installation Hardware

Each site has an individual Master InterFace Unit  (PRE2000MIFU2) specifically built to the site’s unique requirements.

We liaise with the IT provider (either internally or externally) to arrange provision of an available network connection.

The MIFU doesn’t accept inbound connections and all outbound connections are protected via HTTPS. This is required so that the MIFU can communicate directly with the portal to report the status of all the installed equipment.


Following installation of room nodes, heaters and all the necessary connections, our commissioning process requires the Project Manager to visit the site and install the Master InterFace Unit (PRE2000MIFU2).

The MIFU will be paired and calibrated with the individual room control units (PRE2000CU3). A probe is sent around the building’s existing wiring system to test and detect any wiring faults within the Irus network. Faults will be dealt with on site to ensure the entire building is communicating effectively and under complete control of the Irus system before the project is signed off. 


Site requirements are met by creating profiles that control the settings of the equipment being installed. An example profile is for room heaters; we can set the system to have a minimum/maximum temperature; a setpoint temperature; a boost time; a timescale of what to do when no presence is detected; and what to do if a room has been unoccupied for a period of time.

This is customisable and can be configured per room, per area or per building.

If changes to profiles are required or additional profiles are needed, we can do this or configure the system to allow managers onsite to create their own profiles should settings need adjusting.


Handover Documentation

A handover document, specific to each site will be left with the manager at the site for future reference. This contains details of the apparatus installed; information about the Security Hosted Service; Service Level Agreement; Service Support Plan; Procedures for resetting equipment; and a Commissioning Certificate


Service Contract Reports

As part of the Service Contract Agreement we provide a monthly report that is sent to specified recipients. The report will detail any issues that may have occurred over the previous month for the site including;

• Offline Nodes • The detection of supplementary heaters in rooms • Failure to reach agreed setpoints
• PIR glitches • Relay faults • Probe failure (for use with water heating management).

These reports provide an overall condition summary of the system and a cue to notify maintenance teams of any issues.


Irus is an intuitive system, and therefore, requires very little training.

However, when the site has been commissioned the Project Manager will provide a session for Energy / Accommodation Managers and Maintenance / H&S / Welfare / Compliance personnel – to ensure members of staff that access the system are familiar with how it operates.

Training includes familiarisation with the systems infrastructure; understanding the features of the system; operation of each product; a guide to accessing and understanding the information within the online portal; suggested temperature profile settings; future reporting information; and basic trouble shooting.
