2 Installation and Startup

2.1 Install/Replace the Battery

1. Pry the top lip of the mounting bracket up, and lift the bracket off of the

transmitter.

2. Use your thumb to depress the housing release tab on the bottom of the

transmitter; separate the housing.

3. Install the new battery.

4. Press the Reset button to initialize the transmitter.

2.2 Mount an External Thermistor

The transmitter uses an on-board thermistor. If you want to use an external

thermistor:

1. Wire the external thermistor using 24-gauge wire, no more than 40 feet

long.

2. Route the external thermistor wiring through either the rectangular

cutouts on the back of the housing and bracket, or through the rounded

wiring cutout at the top of the housing.

Note: If you want to use the cutout at the top of the housing, you will need

to trim the bracket.

3. Use a small screwdriver to attach the external thermistor wiring leads to

the terminal block.

4. Place a jumper on the external thermistor selection pins, allowing the

transmitter to use the external thermistor in addition to the on-board

thermistor.

5. Press the Reset button to complete configuration.

2.3 Select the Frequency Band

EchoStream products are able to use a range of radio frequencies, and

must be configured for your geographic area. To configure the transmitter:

1. Place a selection jumper on the appropriate frequency band selection

pins.

• Place the jumper on the top two pins, marked NZ, to set the frequency

range to 921-928 MHz for New Zealand.

• Place the jumper on the bottom two pins, marked AU, to set the

frequency range to 915-928 MHz for Australia.

• Leave the jumper off the pins to set the frequency range to 902-928

MHz for North America.

2. Press the Reset button to complete configuration.

Caution: When pressing the Reset button, make sure you don’t also touch

the frequency band selection pins. Touching the frequency band selection

pins while pressing the Reset button can inadvertently set the transmitter

to the wrong frequency band.

3 Program the Transmitter

EN1723 transmitters are programmed at the factory. It is not usually

necessary to reprogram EN1723 series transmitters. If you want to

reprogram the transmitter, parameters can be changed using the

programming header.

4 Mount the Transmitter

1. Attach the mounting bracket to the wall, using either screws or double-

sided tape.

Note: There are two mounting holes for standard installation. An optional

third mounting hole is located under the battery. Use the third mounting

hole to secure the housing to the bracket.

2. Hook the bottom of the transmitter into the bracket’s bottom catch, and

press the transmitter into the bracket so that the bracket’s top lip snaps

into place.
