(Sold Separately)
Any loads, including central air conditioners, can be
managed using a Smart Management Module (SMM).
The system can accommodate up to eight individual
SMM modules.
NOTE: The SMM modules are self-contained and have
individual built-in controllers.

Application Considerations
Generator overload condition is determined by generator
frequency. Loads are shed when frequency is less than
58 Hz for three seconds or less than 50 Hz for ½ second
(for 60 Hz systems).

The Smart A/C Module can be used in conjunction with
individual Smart Management Modules (SMM) to
manage a combined total of eight loads.
• Use Priorities A/C 1-4 on the Smart A/C Module as
the top priorities, then up to four Smart Management
Modules as Priorities 5-8.
•
Use only select A/C priorities on the Smart A/C
Module as the top priorities, then use additional
Smart Management Modules as the remaining
priorities.
• A Smart Management Module can share a priority
with an A/C priority on the Smart A/C Module
provided the generator is sized to handle the
combined surge load from both appliances. Sharing
priorities can allow up to 12 loads to be managed in a
properly sized system.
In any combination of modules, the recovery times after a
loss of utility power or shutdown due to overload are
shown in Table 1.
