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. If replacing a battery, use the hole in the back of the housing to push the
old battery out of the battery holder.
4. Install the new battery.
5. Press the Reset button to initialize the transmitter.
2.2 Attach the External Temperature and Humidity
Sensor
Note: The ACC710 cabling can be trimmed as needed.
To attach the ACC710 external temperature/humidity sensor:
1. Route the four ACC710 wires through the rectangular cutouts on the
back of the housing and bracket.
Note: If you want to use the cutout at the top of the housing, you will need
to trim the bracket.
2. Use a small screwdriver to attach the external sensor wiring leads to the
terminal block in the following order:
a. Attach the Black wire first.
b. Attach the Yellow wire second.
c. Attach the Purple wire third.
d. Attach the Red wire last..
3. Clip the uninsulated silver wire back to the cabling insulation.
4. Press the Reset button to complete the procedure.
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
EN1722 transmitters are programmed at the factory. It is not usually
necessary to reprogram EN1722 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.
