window. The sensor must be installed in the space where the receiving lighting 

controller is operating the light fixtures. See the sections on light level test and 

range confirmation* to aid in optimal placement. * -(requires F series Echoflex 

controller)
The sensor can be mounted using screws (not supplied) through the back plate 

or using double-sided tape or Velcro™ (not supplied).

Linking a Sensor to a Lighting Controller or Receiver

This process requires the controller or receiver to be mounted and powered and 

within range of the sensor to be linked.

1. Activate LEARN or LINK mode at the receiver, if necessary refer to the 

manufacturers documentation.

2. Tap the sensors TEACH button.
3. Deactivate LEARN mode at the receiver.

Selecting the Light Range on the TAP sensor

1. Using a fingernail or small flat head screwdriver, pop the rear mounting 

plate off the sensor to reveal the range slide switch.

2. Slide the switch to the range setting required, 512 lux (50 foot-candles) or 

1024 lux (100 foot-candles). The factory default is 512 lux.

3. Press the rear mounting plate back into position.

Installing or Replacing the Start Assist Battery

The battery is not required  for normal  operation.  The battery may be useful 

for installation purposes (when using the Range Confirmation test and Daylight 

Harvesting test mode, which depletes the energy stores of the TAP quickly.)

1. Using a fingernail or small fl at head screwdriver, pop the rear mounting 

plate off the sensor.

2. To remove old battery: Using a small flat head screwdriver or pen as a lever, 

insert pointed end under the battery’s edge and pop out of the holder.

3. Install or replace the battery in the clip with a new CR2032 coin cell battery 

insuring the battery edge is under the retaining clip and positive side (+) is 

facing up.

4. Press on the rear mounting plate until it snaps back into position.

Test Operating Modes

The following tests can be selected when in test mode.

1. Light level test
2. Range confirmation test
3. Daylight harvesting test mode

Light Level Test: 

This test provides visual feedback of the 

immediate energy produced by the solar panels.
