A corrected template for Multi-Split System Central Air Conditioners and Heat Pumps, Appendix M1, v5.2, has been posted on the CCMS web site.  The correction affects only some models with at least four indoor units.  This new template does not have to be used until the January 1, 2023 effective date of Appendix M1, but any submissions should be made on this v5.2.  Submissions made on a previous version of this template do not have to be resubmitted unless the models submitted contain four or more indoor units.

Instructions for completing the template can be found here.
