11.11. M2 LonTalk ®
®
The optional M2 LonTalk
translates input and output variables between the Lennox protocol and the LonTalk protocol. The M2 LonTalk module has
been developed to communicate with building automation systems that support the LonMark
(SCC) or Discharge Air Control (DAC) functional profiles. A Lennox non−communicating zone sensor or a LonTalk network
zone sensor may be used to send the zone temperature to the M2. Use of a LonTalk thermostat to send direct heating and
cooling demands is not supported at this time.
NOTE − A qualified systems integrator with adequate training and experience is required to integrate and commission the
M2 LonTalk module into a third−party LonTalk building automation system. A LonWorks network configuration software tool
such as LonMaker® (or equivalent) is required to commission the LonWorks network. An external interface file (XIF) will be
made available upon request.
Refer to the Installation Instructions for the M2 LonTalk module for installation. Refer to the Service Literature for the M2
LonTalk module for data point and programming information.
