Chapter 2: Installation

1. Control panel Combus connection

NOTE: If you are using the RTX3 as a stand-alone device, connect an

external 12Vdc power supply to the RED and BLK terminals. Battery backup

is recommended.

2. If the current draw exceeds 150mA on PGM1 or PGM2, use a relay.

Connect the RTX3’s RED connector to the relay’s RED connector, and the

PGM connector (PGM1 or PGM2) to the relay’s BLK connector.

3. Connect PGM3 and PGM4 to external power supplies if you need additional

power. A PS-817 is recommended. Connect the PGM’s N/O connector to

the external power supply’s “+” connection. Connect the power supply’s “-”

connector to the device’s “-” connector. Connect the PGM’s COM connector

to the device’s “+” connector.

NOTE: Write down the serial number of all wireless modules to be used with

the RTX3. If this installation replaces another RTX3, make sure the

programming can be transferred.

power up. In order to reset the system, press and hold the Programming button

for 5 seconds, the BUS RX LED flashes. Release the button and press it again

while the LED flashes to reset the module to its default values.
