• The Remote Access Module provides an interface to Home Automation systems, utilizing the RS-232 serial port connection. NOTE: See the latest version of the SAM Remote Access Interface Specification, available on HVACpartners, for more details on the home automation interface.
• The Remote Access Module is powered with a field-supplied 24VAC transformer. A 120VAC supply must be near the mounting location when using the accessory plug-in 24VAC transformer. Provisions must be made to secure the accessory plug-in transformer to the outlet. The D-wire (24VAC) from the communicating system must NOT be used to power the Remote Access Module and should not be connected to the module. This instruction covers the physical installation and start up. Use this instruction to guide the actual installation process after the communicating system(s) have been installed. One Remote Access Module is capable of handling two communicating systems.
