Installation

Infresco-P 4kW

The infresco-P 4kW is part of a family of controllers designed to provide energy saving

when used with Quartz Infrared Halogen Lamps. The unit has a built in PIR sensor

allowing the lamps to automatically switch on only when people are present. In addition

to the PIR, a temperature sensor monitors the outside temperature and inhibits the

lamps when the temperature exceeds a pre-determined set point of between 1 and 40

degrees Celsius.

The microcontroller-based system 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%.

The lamps are switched on for a fixed time period of 5 minutes. This period is reset

each time the PIR detects any further movement. Installation is simple and once

installed is relatively maintenance free.

Product Features

Significant energy saving - provides heat only when people are present

Extends lamp Life

Temperature monitor – lamps inhibited when ambient temperature exceeds set point

Soft-start/zero-voltage switch-off

Low-cost

Easy to install

Important: Read carefully the following information before installing the unit.

The passive infrared sensor (PIR) fitted in this unit detects changes of infrared energy

through the Fresnel lens on the front face of the unit. The detection area and range

depend significantly on its mounting position. The PIR not only detects movement of the

human body, but also other heat sources similar to the human body.

To prevent false activation, the unit must not be located directly facing or in close

proximity to the heater lamps. Avoid locating the unit near to heating flues/exhausts, air

conditioning units, moving trees/bushes and reflective surfaces.

To prevent malfunction of the PIR sensor, avoid subjecting it to rapidly-changing

temperatures, strong shock or vibration or high humidity and temperature.

Troubleshooting

Problem: Lamps do not switch on.

Solution:

Problem: Lamps do not switch off.

Solution:

1) Check the LINE and LOAD wiring connections to the unit and ensure the mains

2) The ambient temperature may have exceeded the current set point

3) Check the lamps/Lamp fittings.

1) The PIR may be continually being re-triggered due to false activations. Mask

supply is switched on.

temperature.

If necessary, increase the set point temperature (VR1).

the PIR lens to effectively inhibit the PIR. If the lamps switch off approximately

5 minutes, the PIR is receiving false activations. See section ‘Installation’ for

information.
