SA E-BUS Controller Technical Guide
Overview
Features and Applications
Features
The Series A Controller (OE332-23E-VCMX-SA)—SA E-BUS Controller—is designed with 6 analog inputs, 2 analog outputs, and 5 relay
outputs. Most common HVAC unit control applications can be confi gured using only the SA E-BUS Controller; however, if needed, the
SA E-BUS Controller’s input and output capabilities can be expanded
with the SA Expansion Module ( OE333-23-SA) or 12-Relay Expansion
Module (OE358-23-12R) by means of a modular cable. The SA Expansion Module provides an additional 4 analog inputs, 5 analog outputs,
8 binary inputs, and 4 confi gurable relays. The 12-Relay Expansion
Module provides an additional 12 confi gurable relays.
The SA E-BUS Controller can also use the Two Condenser Head Pressure Module ( OE370-23-HP2C) for those applications requiring Head
Pressure Control. The SA E-BUS Controller can also use the WSHP
Module (OE334-23-WPM-A) for W ater Source Heat Pump applications.
Each SA E-BUS Controller can be confi gured for control of VAV Units
(with or without VAV/Zone Controllers), Constant Volume Units, and
Make-Up Air Units. Features include the following:
• Modulating Cooling Output ( Copeland Digital
Scroll™ Compressor or Chilled Water Valve Control)
• Modulating Heating Output ( Hot Water Valve,
Steam Valve, SCR Electric Heat Control)
• Full Integration with the AAON
Hot Gas Reheat Valve Controller
®
MHGRV Modulating
• Confi gurable for Air to Air and Water Source Heat Pump
Applications
• Advanced Dehumidifi cation Capabilities
• Adaptive Supply Air Reset
• Selectable Control Sensor
• Fan Proving Interlock
• Dirty Filter Alarm
• Emergency Shutdown Input (Smoke Detector/Firestat or
other Shutdown Conditions)
• Water Side Economizer Option
• Remote Occupied Capabilities
• 7-Day, 2-Event-per-Day Scheduling
• 14 Holiday Event Scheduling
• Optimal Start Scheduling
• Trend Logging Capability
• Static Pressure Control for Filter Loading Applications
• Head Pressure Control (with optional Two Condenser Head
Pressure Module)
• Additional Water Safeties (with optional Water
Source Heat Pump Module)
Applications
Variable Air Volume Unit
The SA E-BUS Controller can be confi gured to control a VFD Supply
Fan for Duct Static Pressure control. If the unit is not equipped with a
VFD, but Duct Static Pressure control is needed, a modulating Zoning
Bypass Damper can be controlled by the SA E-BUS Controller.
VAV units are typically designed for occupied Cooling with Morning
W arm-up Heating. This option is available with the SA E-BUS Controller. The SA E-BUS Controller can also be used for a Zoning System that
needs Duct Static Pressure control and Occupied Cooling and Heating.
The SA E-BUS Controller also has the ability to be confi gured for Duct
Static Pressure Control by controlling the Supply Fan VFD for the purpose of maintaining proper Duct Static Pressure in response to varying
fi lter loading conditions.
The SA E-BUS Controller allows Dehumidifi cation Priority on a VAV
unit. This could be useful on a building with a very low internal sensible
load, but which has a high internal and/or external latent load. During
VAV Dehumidifi cation, the SA E-BUS Controller activates Cooling
based on the Evaporator Coil Temperature and activates
lating Hot Gas Reheat to warm the Supply Air Temperature to the Active
Supply Air Temperature Setpoint.
Constant Air Volume Unit
The SA E-BUS Controller can be confi gured to activate a Constant
Volume Supply Fan. In most cases, this is a very basic unit with Space
Temperature control.
Make-Up Air Unit
The SA E-BUS Controller can be confi gured for 100% Outdoor Air
control for Make-Up Air. All HVAC Modes are determined from the
Outdoor Air Sensors. The Outdoor Air Volume must always be at least
50% or higher to be confi gured for Outdoor Air control.
Single or Dual Cabinet Unit
The SA E-BUS Controller can control an SA Series Single Cabinet Unit
or an SA Series Dual Cabinet Unit. Wiring for Dual Cabinet Units is
shown and noted on applicable Single Cabinet Unit diagrams.

Installation & Wiring
Important Wiring Considerations
Zone
Zone
General
Correct wiring of the SA E-BUS Controller is the most important
factor in the overall success of the controller installation process. In
general, most SA E-BUS Controllers are factory installed and wired at
the AAON
®
factory.
Controller Mounting
When the controller is to be fi eld mounted, it is important to mount the
controller in a location that is free from extreme high or low temperatures,
moisture, dust, and dirt. See Table 1 for a list of the required operating
conditions for the SA E-BUS Controller and associated modules.
The SA E-BUS Controller is housed in a plastic enclosure. It is designed
to be mounted by using the 3 mounting holes in the enclosure base. The
SA E-BUS Controller needs to be installed in an environment which can
maintain a temperature range between -30°F and 150°F not to exceed
90% RH levels (non-condensing). It is important to mount the controller
in a location that is free from extreme high or low temperatures, moisture,
dust, and dirt. Be careful not to damage the electronic components when
mounting the controller.
Considerations
The SA E-BUS Controller and associated modules must be connected
to a 24 VAC power source of the proper size for the calculated VA load
requirements. All transformer sizing should be based on the VA rating
listed in Table 1.

Warning: When using a single transformer to power more
than one controller or expansion module, the correct polarity must
always be maintained between the boards. Failure to observe correct
polarity will result in damage to the SA E-BUS Controller and
associated modules.
Please carefully read and apply the following information when wiring
the SA E-BUS Controller or its associated modules. See Figure 5 on
page 11 for the SA E-BUS Controller wiring diagram. See Figures 16
and 17 on pages 20 and 21 for SA Expansion Module wiring. And see
Figure 25 on page 31 for 12-Relay Expansion Module wiring.
1. All wiring is to be in accordance with local and national
electrical codes and specifi cations.
2. Minimum wire size for 24 VAC wiring should be 18-gauge.
3. Minimum wire size for all sensors should be 24-gauge.
Some sensors require 2-conductor wire and some require
3-or 4-conductor wire.
4. Be sure that all wiring connections are properly inserted
and tightened into the terminal blocks. Do not allow wire
strands to stick out and touch adjoining terminals which
could potentially cause a short circuit.
5. When communication wiring is to be used to interconnect
SA E-BUS Controllers together or to connect to other
communication devices, all wiring must be plenum-rated,
minimum 18-gauge, 2-conductor, twisted pair with shield.
WattMaster can supply communication wire that meets this
specifi cation and is color coded for the network or local
loop. Please consult your WattMaster distributor for
information. If desired, Belden #82760 or equivalent wire
may also be used.
6. Before applying power to the SA E-BUS Controller, be sure
to recheck all wiring connections and terminations
thoroughly.

The Suction Pressure Transducer is used to measure suction pressure
at the HVAC unit’s DX evaporator coil suction line. This suction line
pressure is converted to saturated refrigerant temperature by the SA EBUS Controller. This temperature is used by the SA E-BUS Controller
to accurately control the compressors and reheat cycle components to
provide optimum performance from the system during Dehumidifi ca-
tion operation.
