WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-
to-24VAC. Failure to observe polarity will result in damage to one or more of
the boards. Expansion Module must be wired in such a way that the
expansion module and the controller are always powered together. Loss of
power to the expansion module will cause the controller to become
inoperative until power is restored to the expansion module.

Note:
1.) The Modulating
Cooling Device Used
Must Be Capable Of
Accepting Either A 0-
10 VDC, 2-10 VDC or
1.5-5.0 VDC Input.
The Modulating
Cooling
Output Voltage
Is User Configurable For
These Voltages. The
Modulating Heating
Devices Used Must Be
Capable of Accepting
Either A 0-10 VDC or 2-
10 VDC Input. The
Modulating Heating
Output Voltage Is User-
Configurable For These
Voltages. These Voltage
Outputs Must Also Be
Configured When You
Are Setting Up The SA
Controller(s) Operating
Parameters.
2.) Each Modulating
Heating Or Cooling
Device Used On The SA
Controller Must Have (1)
Relay Output Configured
For Each Device Used,
In Order To Enable The
Modulating Heating
And/Or Cooling Device's
Sequence. This Relay
Output Must Be
Configured When
Setting Up The SA
Controller Operating
Parameters.
Relay Output Contacts R1 Through
R4 May Be User-Configured For The

SA Expansion Module
Orion No.:OE333-23-SA
AAON No.:
R96180
The SA Expansion Module must be connected to 24 VAC as shown in
the wiring diagram below. Please see Table 1 on page 10 for correct VA
requirements to use when sizing the transformer(s) used for powering
the expansion module.
Also please note that when wiring the SA Expansion Module, its contacts
must be wired as wet contacts (connected to 24 VAC).
