Application Note
Room Controller application for use with an
Outdoor Contact Input Photocell
Overview
The Room Controller can utilize a standard Outdoor Contact Input Photocell (PPS-5) to provide On/Off
control of the lighting loads based on a daylight threshold.
Description
The Room Controller low voltage interface ports provide +24 VDC to power the Keypad(s) Slider Station,
Daylight Sensor and Occupancy Sensors(s). The external +24 VDC power is limited to 90mA. The Outdoor
Contact Input Photocell draws a maximum of 35mA per sensor and is the largest consumer of external dc
power.

Implementation
Applications that require the use of an Outdoor Photocell to control exterior lighting can be achieved by
using the Outdoor Contact Input Photocell (PPS-5) with a Room Controller. It is possible to also connect
other controls to the Room Controller as long as the 90mA available power is not exceeded.
If using the Outdoor Contact Input Photocell, occupancy sensors cannot be used as their operation will
conflict with the PPS-5 control logic. The Outdoor Contact Input Photocell (PPS-5) is connected to the
Room Controller Input/Output Device (Model # OCC-RJ45) which connects to the Room Controller RJ45
port 3 or 4 via Cat 5 cable.
When the Outdoor Contact Input Photocell (PPS-5) does not detect adequate light levels it provides a closure to the Room
Controller which will turn ON the desired lighting loads. When the Outdoor Contact Input Photocell (PPS-5) detects adequate
ambient light levels it will automatically turn OFF all lighting loads
Wiring Information
Wire the Outdoor Contact Input Photocell (PPS-5) to the Room Controller Input/Output device (OCC-RJ45) as shown in
Figure 1 below.

Programming Information
In order for the Outdoor Contact Input Photocell (PPS-5) to turn ON the lighting loads within the Room Controller the Room
Controller must be put into the Occupancy Auto On Mode. This is done by moving DIP Switch #3 and #4 into the On (UP)
position.
The Outdoor Contact Input Photocell (PPS-5) will now turn ON the lighting loads when the ambient light level is low and turn
OFF the lighting loads with the ambient light level is high.
By default the ON scene is all relays ON and all dimmers to 100%. Use the Room Controller Personal Remote (HHPR-RC) to
adjust the Automatic On scene to any desired light level.
