Determine how the relays are to be grouped and connect them to
the Time/Photo Controller. A maximum of 4 relays can be
controlled by each relay output. If occupant control is desired,
connect 2-wire switches in parallel with the Controller outputs.
If a larger group of relays is to be switched with a Controller
output, use a relay scanner (WR-8812 or WR-8824). Connect a
Controller output to the switch input of the scanner. Actuating this
input will switch all relays connected to the scanner. Connecting a
switch to the same input provides a manual occupant override.
In panels that have several groups, use a programmable relay
scanner (WRS-2224) to permit convenient, keypad assignment of
relay groups to a Controller output.

Multiple Relay Panels
■
■
■
Projects that have several panels can be controlled by one
Time/Photo Controller signaling relay scanners which in turn
switch the relays.
A simple wiring strategy is to interconnect the relay panels with a
multi-conductor bus. All of the Controller's outputs are then
available in each panel. Connect the appropriate output(s) to the
relay scanner(s) installed in the panel.
Up to 20 scanners can be controlled by each Controller output.
The wiring distance for controlling scanners is 2000'.

With no Remote Sensor connected, use the Controller's
astronomic features to switch exterior lighting from Dusk-to-Dawn.
With a Remote Sensor connected, use Controller's keypad to set
specific light levels for each Controller output to be switched.
Point Sensor to the northern sky for most consistent readings.

A 10 conductor bus will provide complete access to all 8 Time/Photo
Controller outputs plus the 24V signal power and return.
To provide convenient override, connect a master switch station in
parallel with the 8 Time/Photo outputs.

8 Output Time/Photo Controller
OPTIONAL REMOTE SENSOR
First determine what the relay groups are and number them.
■
Ensure that the WTP-4408's outputs are correctly connected to
the relay groups - either a direct connection to a relay or a
connection to a relay scanner controlling a group of relays.
■
Manually actuate an output with the time Controller's override
function. Use this feature to test the connections.
PROGRAMMING
■
■
■
■
The following completed table represents a typical Light Industrial
Office Building utilizing 5 of the timer's outputs.
The Instruction Manual provided with the WTP-4408 includes
blank programming schedules. Photocopy these schedules and
make up tables similar to those shown below.
Refer to the Instruction Manual for detailed programming directions.
■
The sensor (WPS-5527) is weatherproof and is designed to
withstand harsh climate. However, when possible mount the
sensor either indoors pointing outward or in a sheltered area.
The sensor's measurements will be less affected
by dirt, ice or snow build-up. If mounting
outdoors, try to shelter the sensor from the
elements. For example, mount the sensor
on the underside of the junction box.
The sensor has a plastic mounting nipple
that can be threaded to a 1/2" pipe thread.
A mounting nut is also supplied to suit
mounting to a 1/2" knock-out.
N
Do not mount the sensor so that artificial
light shines directly upon it.
