damage is found, the receiving party must contact
the last carrier immediately, preferably in writing,
requesting inspection by the carrier’s agent.
General
The equipment covered in this manual is to be installed
by trained, experienced service and installation
technicians. Please read entire manual before
proceeding.
While these instructions are intended as a general
recommended guide, they do not supersede any national
and/or local codes in any way. Authorities having
jurisdiction should be consulted before the installation
is made. See Getting Other Information and
Publications for information on codes and standards.
These instructions explain the operation, installation
and troubleshooting of the MC5000 series controllers.
All internal wiring is complete. Only attach low voltage
eld wiring to designated terminal strips.
The MC5000 series is for use with units with or
without economizers, can be congured for use
with heat pumps and has both humidication and
dehumidication control features.
It is recommended that a 5-minute compressor time
delay relay be installed in each unit if not so equipped.
The MC5000 series controller is suitable for both 50
and 60 HZ operation, and is fully congurable such
that it can be used in virtually any installation. See
Basic Controller Specification/Features on page
18 for further information.
Theory of Operation
The controller is used to control up to six wall-mount
air conditioners or heat pumps with one control.
All models should be the same (humidication and
dehumidication options can vary). It can provide total
redundancy for the structure and equal wear on units.
Units with or without economizers can be used and it is
recommended that units be equipped alike.
The MC5000 can be congured for an alternating or
non-alternating lead/lag sequence. This allows the user
more control on how units will stage on and still allow
for even usage.
If the base controller (MC5300-C or MC5600-C) was
initially installed, the system can easily be upgraded.
The MC5000 series controller can be equipped with an
alarm board that can be factory installed or installed at
any time in the eld.
Upgrading to a system with alarm boards can be
accomplished by installing the boards in the provided
screw-in slots and terminals within the controller. The
eld installation will require the provided snap-in wire
harness and building alarm circuitry to be wired to the
MC alarm boards.
There is an Ethernet-based remote communication port
on the back of the touch screen display (P/N 8612-
065) that comes standard with each unit. The Ethernet
connection allows for network connectivity and remote
control. IMPORTANT: When connecting this product
from a remote location, ensure that the network
connection is secure and reliable.
