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.
