Relays #2 through #21 can be individually confi gured. By using the
4 relay outputs available on the SA Controller, the 4 relays on the
SA Expansion Module, and the 12 relays on the 12 Relay Expansion
Module, you have the ability to confi gure up to a combined total of 20
Heating Stages, Cooling Stages, and the rest of the options listed above.
Only the Heating and Cooling relays can be confi gured with multiple
outputs. If any other option is selected more than once, it will simply
activate redundant relays, but no multiple staging will occur. Default
is “Not Used.”
