3.1.1 Sensor adjustment
Fig. 2 shows the way coverage alters with ceiling height and with
adjustments of the METER dial setting.
Section 4.2.3 shows how tilting and rotating the sensor can produce
different fields of coverage.

If the METER control is turned to – the coverage diameter is
substantially reduced.
We do not recommend the use of these units with ceiling heights
greater than 4.5m.
3.1.2 Helpful tips for installation
As the sensor responds to temperature change or moving heat sources,
please avoid the following conditions:
• Avoid highly reflective surfaces within the detection range.
• Avoid movable objects e.g. curtains and plants in the detection range
(these may cause erroneous detections when moved by air flow from
fans or air conditioner).
• Avoid heat sources (e.g. heating vents, radiators, air conditioners
and filament lamps) in detection range.
• Avoid fans drawing air across the sensor lens.
3.3 Installation procedure
3.3.1 To install the detector, cut a hole with diameter of 65mm in the
ceiling board and bring the power cable through the hole. Strip off
cable sheath and core insulation according to Fig. 6.
3.3.2 Unscrew protection covers on power box with a cross point
screwdriver. The RJ11 socket (use sensor A only) is for sensor connection
and screw terminals are for power and load(s). (See Fig. 7).

Instructions
2.1 Features
The PDFM362 PDFM361 controller is a ceiling flush mount
presence detector for indoor applications in commercial and
domestic locations. PDFM361 covers lighting applications only,
whereas PDFM362 can control lighting and HVAC
(heating, ventilating and air conditioning) applications.
Adjustment of Time and LUX value can be made either by the dial
controls on the sensor body or by the IR10 Infrared remote control.
• PDFM362 has two relays for outputs load I and load II:
load I is for lighting control and load II has voltage free contacts
for HVAC control which operate at all LUX (light) levels.
• Automatically adjusts to fit in a wide range of ceiling thicknesses.
• The sensor has a very high density of sensitive beams covering the
detection area. These are evenly distributed ensuring no dead spots
and detection of the smallest movements.
• RJ11 plug and socket for quick and easy connection.
• Built in LED in sensor giving confirmation of remote control settings
and easy test operation.
