Carrier Infinity HVAC System 'Themostat'
Interfacing to a Carrier Infinity HVAC System can be accomplished using the ELK-M1XSP connected to the Home
Automation Connection (RS-232) Port on the Infinity System Access Module "SAM" model # SYSTXCCSAM01. The
SAM supports two (2) Carrier Infinity HVAC systems. Each system can support eight (8) zones. The ELK-M1XSP can
communicate with up to 16 Thermostats. Refer to LIMITATIONS AND NOTES BELOW. The firmware in the M1XSP
MUST be manually updated to version
40.0.6 or greater
. Firmware updates may be obtained from the Elk website.
Requirements:
1. ELK-M1G or ELK-M1EZ8 Control
2. ELK-M1XSP Serial Port Expander
3. Carrier Infinity System Access Module (SAM)
M1XSP Configuration:
1. Select an address from 1 to 7 using the 4-position dip switch, then enroll the M1XSP into the M1 system.
2. Update the M1XSP with firmware version
40.0.6
or later.
3. Remove jumper JP5.
4. Set Baud Rate Jumpers S1 = 1, S2 = 1, S3 = 1.
5. Set Mode Jumpers S5 = 1, S6 = 1, S7 = 1, S8 = 1
6. Select “232” for Jumper JP3.
7. Connect a standard 9 Pin serial cable between the M1XSP and the Carrier Infinity System Access Module (SAM).

It is Elk's understanding that different
models of SAM modules are available and
that each model retains the Home
Automation Connection (RS232) regardless
of the interface technology. However, it is
ultimately the responsibility of the Installer
to make sure the correct SAM module is
selected and that it includes the RS232
connection.
