## **Introduction** 

The Infresco-CT 4kW is part of a family of controllers designed to provide energy saving efficiencies, when used with quartz infrared halogen lamps or other heating and lighting loads. The ‘CT’ model switches the load on for a pre-determined time period, of between 1 and 60 minutes. The controller output can also be switched on and off manually, by touching the front panel of the unit. The microcontroller-based unit incorporates zero-voltage switching and a soft-start function to eliminate high initial inrush current which can potentially increase lamp life by as much as 30%. Installation of the unit is simple and once installed is relatively maintenance-free. 

## **Product Features** 

-  Energy saving – provides heat for a pre-determined time period. 

-  Extends lamp Life. 

-  Soft-start/zero-voltage switch-off. 

-  Low-cost. 

-  Easy to install. 

Applications: patio areas, smoking shelters, restaurants, warehouses, workshops and garden lighting.

Use this template to locate the 4 mounting-hole centres prior to drilling. **IMPORTANT! Drilling of any holes through the enclosure will immediately invalidate the warranty of the unit. The unit MUST be orientated with the cable** © **glands facing down.** © 

## **Installation** 

**Important** : Carefully read the following information before installing the unit. 

The Infresco-CT 4kW should be attached securely to a vertical surface using the four mounting holes accessible from the front of the unit. Remove the lid to access the mounting holes. To ease installation, a mounting template is provided on the next page to locate the 4 mounting hole centres. 

## **IMPORTANT! The unit must be orientated with the cable glands facing down.** 

## **Wiring** 

It is recommended that installation and maintenance of this equipment should be done with reference to the current edition of the I.E.E. wiring regulations (BS7671) by suitably qualified/trained personnel. The I.E.E regulations contain important requirements regarding safety of electrical equipment (for International Standards refer to I.E.C/ directive IEC950). 

**Warning! Isolate the mains supply before commencing any work on this unit. Ensure all earth wires are connected to maintain earth continuity to the lamp fittings.** 

The unit is fitted with two cable glands. Only one cable should be fitted per gland to prevent degrading the unit’s IP rating. When fitting two loads, refer to ‘Wiring Diagram’ for an alternative wiring configuration using a junction box. 

The mains supply connects to the terminal block marked ‘ **LINE** ’. Connect the supply **LIVE** to the ‘ **L** ’ terminal, **NEUTRAL** to the ‘ **N** ’ terminal and **EARTH** to the ‘ **E** ’ terminal. 

**Commissioning** 

Set the on-time preset (VR1) to a time period of between 1 and 60 minutes. VR1 is located at the top of the printed circuit board as shown in the Wiring Diagram. Replace the lid and switch on the mains supply to the unit. To turn the load on touch the centre of the switch symbol on the front panel. To turn the load off touch the switch symbol on the front panel again. When the load is on, it will switch off automatically, after the time which has been set on VR1, has expired. 

## **Technical Specification** 

**Supply Voltage** 230VAC +/- 10% 50/60 Hz **Switching Capacity** 4kW Max. **Lamp On-Time** 1 to 60 minutes (VR1 Preset) **Current Consumption (control circuit)** 50mA **Terminals** 2.5mm[2] Rising Clamp **Operating Temperature** -20 to 40°C **Protection Rating** IP65 **Gland Diameter** Max Cable Entry 2.5mm² **Enclosure Dimensions (WxLxH)** 120x90x50 (mm) 

The load connects to the terminal block marked ‘ **LOAD** ’. Connect the load **LIVE** to the ‘ **L** ’ terminal, **NEUTRAL** to the ‘ **N** ’ terminal and **EARTH** to the ‘ **E** ’ terminal. If two lamps are to be fitted they must be wired in parallel.
