What does an interlocked LOSSNAY unit indicate in a group?
An “Interlocked LOSSNAY ON” or “Interlocked LOSSNAY OFF” icon appears when the LOSSNAY unit is linked to the indoor units' operations but not independently running. This status can be confirmed on the [Floor] or [Block] display by selecting the respective group (Page 14).
