Introduction
The Infresco-T 4kW is part of a family of controllers designed to provide energy saving when used with Quartz Infrared
Halogen Lamps or other Heating and Lighting Products. The ‘T’ model switches the lamps on for a pre-determined
time period of between 1 and 40 minutes.
The microcontroller-based unit incorporates zero-voltage switching and a soft-start function to eliminate the lamps’
initial high inrush current – potentially increasing lamp life by as much as 30%. Installation of the unit is simple and
once installed is relatively maintenance-free.
Installation
Important: Read carefully the following information before installing the unit.
The Infresco-T 4kW should be fixed securely 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. These 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 lamps, 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.
The lamps connect 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.
Check all wiring and make sure the cable glands are tightened.
Commissioning
Set the on-time pre-set (VR1) to a time period of between 1 and 40 minutes. VR1 is located at the top of the printed
circuit board as shown above. Replace the lid and switch on the mains supply to the unit. Press the push-button on the
front of the unit to switch the lamps on.
MOUNTING TEMPLATE
Use these template dimensions 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.

regulations contain important requirements regarding the safety of electrical equipment.
ELECTROSTATIC DISCHARGE (ESD)
This product range has been identified has requiring protection from electrostatic discharge (ESD). They include
integrated circuits (IC’s) that may be damaged or degraded if mishandled. They are much less vulnerable when built
in-circuit and suitable and sufficient precautions are taken when being handled.
To address this matter, when the products are sold separately they are protected in an ANTI-STATIC polyethylene
bag.
Appropriate care should be taken when handling the units for installation.
