INSTALLATION AND WIRING
Electrical and Environmental Requirements
General
Correct wiring of the AAON unit controller and its modules is
the most important factor in the overall success of the installation
process. The AAON unit controller and modules are installed and
wired at the AAON factory. Some of the following information
may not apply to your installation if it was pre-wired at the
factory. However, if troubleshooting of the controller or modules
is required, it is a good idea to be familiar with the system wiring.
Wiring
The modules must be connected to an 18-30 VAC power source
of the proper size for the calculated VA load requirements. All
transformer sizing should be based on the VA ratings listed in
Table 1, this page.
NOTE: If the temperature at the controller is below -4ºF
(-20ºC), the display refresh rate could be less
responsive.
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 AAON unit controller,
RSMVQ, and any associated module.
Please carefully read and apply the following information when
wiring the unit controller, RSMVQ, and any associated module.
1. All wiring is to be in accordance with local and
national electrical codes and specications.
2. All 24 VAC wiring must be connected so that all
ground wires remain common. Failure to follow this
procedure can result in damage to the controller and
connected devices.
3. Minimum wire size for 24 VAC wiring should be
18-gauge.
4. Minimum wire size for all sensors should be 24-gauge.
Some sensors require two-conductor wire and some
require three-or four-conductor wire.
5. Minimum wire size for 24 VAC thermostat wiring
should be 22-gauge.
6. Be sure 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.
7. When communication wiring is used to interconnect
AAON unit controllers together or to connect to other
communication devices, all wiring must be plenum-
rated, minimum 18-gauge, two-conductor, twisted pair
with shield. AAON can supply communication wire
that meets this specication and is color coded for
the network or local loop. Please consult your AAON
distributor for information. If desired, Belden #82760
or equivalent wire may also be used.
8. Before applying power to the AAON unit controller,
RSMVQ Modules, and any associated modules,
be sure to recheck all wiring connections and
terminations thoroughly.
Powering Up
When the controller and modules are rst powered up, the
POWER LED should light up and stay on continuously. If it
does not light up, check to be sure you have 24 VAC connected
to the controller, that the wiring connections are tight, and they
are wired for the correct polarity. The 24 VAC power must be
connected so all ground wires remain common. If after making
all these checks, the POWER LED does not light up, please
contact AAON Controls Support for assistance.
