Description

Infresco-VR 4kW Remote Dimmer & Variable Infrared Controller

The Infresco-VR Remote Dimmer 4kW is a versatile and energy-efficient variable power controller designed to provide precise control of infrared heaters in outdoor, commercial, and light industrial environments. Developed with occupant comfort, system longevity, and energy efficiency as core priorities, this controller is specifically engineered to manage the high in-rush currents associated with infrared heating and lighting systems.

With a maximum load capacity of 4kW, the controller incorporates an advanced soft-start function that gradually applies power to connected heaters. This significantly reduces electrical stress during start-up, helping to extend heater lamp life by up to 30% while also simplifying installation. Featuring ten incremental variable power settings, the Infresco-VR allows users to fine-tune heat output to achieve the ideal comfort level for any space.

Once switched on and configured, the controller can automatically manage the heating system when used with optional energy-saving accessories. An optional temperature sensor continuously monitors ambient conditions, ensuring heaters operate only when the temperature falls below the selected set point. Additionally, an optional Passive Infrared (PIR) sensor detects movement, activating heaters only when occupancy is present to minimise unnecessary energy consumption. For added convenience, this model supports an optional remote control handset, enabling remote power adjustment and system shut-off.

Key Features

• Soft-Start Technology – Gradually energises heaters to reduce in-rush current and extend lamp life by up to 30%.

• Remote Variable Control – Adjustable heat output via optional remote handset for enhanced user convenience.

• Manual Variable Power Settings – Ten incremental control levels to optimise comfort in different environments.

• Energy-Efficient Operation – Heaters operate only when required when used with optional sensors.

• Temperature Monitoring – Optional temperature sensor activates heaters only below the preset temperature.

• PIR Motion Detection (Optional) – Detects occupancy to prevent unnecessary heating and reduce energy usage.

• Robust Outdoor Construction – IP65-rated enclosure suitable for demanding outdoor conditions.

• Designed for Infrared Heaters – Optimised for high in-rush current loads common in IR heating systems.

Applications

The Infresco-VR Remote Dimmer 4kW is ideal for applications requiring controlled management of infrared heating loads, including:

• Outdoor Heating – Patios, terraces, garden areas, smoking shelters, and outdoor dining spaces.

• Commercial Environments – Restaurants, cafés, bars, hospitality venues, and leisure facilities.

• Industrial Settings – Warehouses, workshops, and covered loading areas using infrared heating lamps.

This controller provides a cost-effective solution for businesses seeking reliable, user-friendly, and energy-efficient heating control.
