HPCP3BC (HPCU3BC and HPSA)

Basic Outdoor Controller

Installation and Setup

The HPCU3BC Basic Outdoor Controller is an

intelligent component for simple control of

exterior lighting. It must be used in conjunction

with the HPSA Photocell Sensor. HPCP3BC is a

package combining both the controller and the

sensor.

The HPCU3BC accepts two inputs: the HPSA sensor,

which provides exterior daylight levels, and an

additional dry contact input which indicates normal

building occupancy. The controller also provides three

intelligent outputs, each dedicated to one type of

outdoor lighting: Security, Parking and Signage. Each

output can drive up to three relays in parallel.

The HPCU3BC provides built-in intelligent scenarios

for each type of outdoor lighting. Each output has its

own adjustable set point to indicate what level of

daylight (or darkness) should trip the lighting on.

The HPCU3BC is designed for use with Reliant Relay

H2R series or GE RR series relays installed in a

Horton Controls lighting control panel or an accessory

cabinet as detailed on the following page.

Features

• Built-in intelligent scenarios for outdoor lighting

• Three intelligent outputs for three types of outdoor

lighting

• User-selectable ranges for three independent light

levels

• Built in “deadband” to avoid nuisance switching

• Optional egress delay for parking lot lighting

• “Occupied” contact to indicate normal working

hours

Before proceeding, read the enclosed installation

instructions. If you have any questions, call our

Service Team at: 888-852-2778.

CAUTION: Make sure all power to the

lighting control panel is off before

wiring. Do not energize wiring until

the units are fully assembled. Conform

to all applicable codes.

Basic Installation Steps

Detailed installation instructions follow.

1 Install the photocell sensor on the roof

2 Mount the control unit in the lighting

control panel or accessory cabinet

3 Wire the sensor to the photocell input

4 Wire 24 VAC power to power input

5 Wire intelligent outputs to relays to be

controlled

6 Connect a timeclock, switch or other

input to “occupied” contact

7 Select light levels and parking lot

“egress delay”

8 Test operation

Install the Sensor

(You may wish to install the photocell

sensor last, but wire it to the panel in the

electrical closet for testing as described

on page 4).

Mount the HPSA Photocell Sensor on

the outside of a weathertight junction

box on the building roof, facing toward

the northern sky as illustrated in Figure

1. Make sure the sensor lens is not

subject to shadows or directly aimed at

parking lot lights. In areas subject to

snow, the sensor must be mounted 12

inches above the snow line.

Mount the Control Unit

There are two recommended ways to

install the HPCU3BC controller:

1 In a Lighting Control Panel. A com-

plete panel assembly includes the

following components:

• Tub (HTUB12/24/48)

• Cover (HCVR12xx/24xx/48xx)

• Interior* (HIN series)

• Power Supply (HPSM115/277)

• Relays (Reliant Relay H2R7P/9P or

• GE RR7P/9P )

2 In an Accessory Cabinet next to the

lighting control panel. Order HSMC2

12- and 24-relay interiors each hold one or two

controllers on the accessory bracket. A 48-relay

interior holds 1 to 4 controllers.

Note: Be certain to observe proper

polarity, or the controller will not

operate properly.

Wire the Intelligent

Outputs

The HPCU3BC Controller has three

Intelligent Outputs labeled Security,

Parking and Signage. Each intelligent

output may be wired to drive either:

1 A single relay in the lighting control

panel

2 A group of relays hardwired in parallel

in the panel

interior, due to their intelligent channel inputs for

surface-mount accessory cabinet with

cover, which holds up to four (4)

HPCU3BC control inits.

Details for assembling a complete

Lighting Control Panel are outlined

separately in installation instructions for

Watt Stopper interiors (INHINBC,

INHINSC, INHINSS and INHINCC).

Once the panel is assembled and relays

are connected to the motherboard, the

HPCU3BC may be mounted in the low

voltage section of the panel on the

accessory bracket or in the separate

accessory cabinet, and wired as detailed

below.

Wire the Sensor to the

Control Unit

Run 3-conductor 20 AWG wire from the

HPSA photocell sensor back to the

panel and terminate on the HPCU3BC

controller as illustrated in Figure 3.

Wire 24 VAC Power

Using 2-conductor 20 AWG wire,

connect the 24VAC and WHITE power

input terminals on the HPCU3BC to the

24VAC and WHITE accessory power

terminals on the lighting control panel

motherboard.

working hours (closed contact) or after

hours (open contact). It may be wired to

a wall switch, a timeclock or other

building automation system as shown in

Figure 3.

Select Light Levels

Each output has an associated dial to

set the desired light level at which the

lighting group should be switched on or

off. (There is a “deadband” of approxi-

mately 5 seconds to avoid nuisance

switching).

As the label on the unit indicates, the

light levels for Security and Parking may

be set on the dial from 1 (2 fc) to 10 (20

fc) in 2 footcandle increments. Signage

panel, such as a Channel in an SC or

See INHINSC or INHINSS installation

instructions.

Determine which relays or intelligent

inputs are to be controlled by each

output. Wire from the output RED,

BLACK and WHITE terminals to the

corresponding terminals in the lighting

control panel as shown in Figure 3.

Wire the ‘Occupied’

Contact

The occupied contact accepts a dry

contact input to indicate when the

building is operating under normal

levels may be set from 1 (20 fc) to 10

(200 fc) in 20 footcandle increments.

Recommended settings are:

Security 6 fc (Setting 3)

Parking 6 fc (Setting 3)

Signage 40 fc (Setting 2)

Select Egress Delay

The Parking output has an additional dial

to set the “Parking Egress” delay. This

time delay allows building occupants to

get to their cars in a lighted parking lot

after the building goes “unoccupied.” The

Parking Egress dial may be set from 0

(15 minutes) to 8 (2 hours) in 15-minute

increments. Setting 9 on the dial

provides a one-minute test.

Test Operation

When all wiring and settings are complete,

restore power to the lighting panel.

Test the expected sequence of operations

in the building to ensure that all controls

are operating as intended. An example

follows. This example assumes you are

testing during daylight hours. If testing at

night, provide a light to shine at the

photocell sensor.

1 Begin with the occupied contact in the

open position (the building is “unoccu-

pied”). Set the PARKING EGRESS dial

to 9 for a one-minute test.

2 Test the photocell sensor’s responsive-

ness by sliding the PHOTOCELL

switch on the HCPU3BC unit to TEST.

Cover the sensor to simulate dark-

ness. Security lighting should turn on.

3 Close the occupied contact (the

building is now “occupied”). If the

photocell sensor is still covered, both

parking and signage lighting should

turn on.

4 Open the occupied contact (the

building is now “unoccupied”). Signage

should turn off. Parking lot lighting

should stay on for one more minute.

5 Uncover the photocell sensor. All

exterior lighting groups controlled by

this unit should turn off.

6 Return to normal operation. Slide the

PHOTOCELL switch back to the

OPERATE position. Set the PARKING

EGRESS dial to the desired time

(minimum of 15 minutes at the “0”

setting). If the photocell sensor is not

yet installed on the roof, install and

wire it as shown in Figure 1 on page 2.
