The following are considerations concerning
powering the SAQM.
• Recommend connecting SAQM to the S40 using
the provided splicing connectors. Both devices
will be powered by the indoor unit transformer
as long as no other equipment is attached
(see "Figure 4. Using Indoor Unit Power and
Connecting at Thermostat" on page 12).
• If additional equipment other than the S40
and SAQM are connected to the indoor unit
transformer then an additional transformer is
required.
