PRODUCT FEATURES & BENEFITS
Significant energy saving - provides heat only when people are present
INTRODUCTION
The infresco-P 6kW is part of a family of controllers designed to provide energy saving
when used with Quartz Infrared Halogen Lamps or other Heating Lighting Products.
The ‘P’ model 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 5 and 25 degrees Celsius. Designed with ease of
wiring in mind, this unit is ideal for controlling up to four 1.5kW lamps through the use of
two additional cable entry points.
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% and reducing the stress on the mains supply.
The lamps are switched on for a pre-determined time period of between 5 and 30
minutes. This period is reset each time the PIR detects any further movement.
Installation is simple and once installed is relatively maintenance free.

INSTALLATION
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.
WIRING
Warning! Ensure the mains supply has been isolated before wiring this unit.
Failure to do so could result in serious injury or fatality.
The unit is fitted with three cable glands. Only one cable should be fitted per gland to
maintain the unit’s IP rating. Two additional cable glands can be fitted to allow the
connection of up to four lamps. See Figure 2.
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. The load
connections are paired to allow the connection of several lamps.
Important: Ensure all earth wires are connected to maintain earth continuity to
the lamp fittings.
If the ‘Enable’ input is not being used, make sure a link is fitted between the ‘COM’ and
‘INPUT’ terminals (CN3).
Connect the 3-way plug to the socket marked ‘PIR SENSOR’ (CN4).
Check all wiring - particularly the Line, Earth and Load connections and make sure the
cable glands are tightened.
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).
