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.
