SHIPPING DAMAGE
Upon receipt of equipment, the carton should be checked
for external signs of shipping damage. If damage is
found, the receiving party must contact the last carrier
immediately, preferably in writing, requesting inspection
by the carrier’s agent.
GENERAL
These instructions explain the operation, installation and
troubleshooting of the MC4000 controller.
All internal wiring is complete. Only attach low voltage
field wiring to designated terminal strips.
The MC4000 is for use with units with or without
economizers, can be configured for use with heat pumps,
and has a dehumidification control feature if an optional
humidity controller is connected.
Each unit should be sized to handle the total load of the
structure if 100% redundancy is required.
It is recommended that a five (5) minute compressor
time delay relay be installed in each unit if not so
equipped.
The MC4000 controller is suitable for both 50 and 60
HZ operation, and is fully configurable such that it can
be used in virtually any installation. See Controller
Programmable Features and Default Settings.
THEORY OF OPERATION
The controller is used to control two wall mount air
conditioners from one control system. It provides total
redundancy for the structure and equal wear on both
units. It can be used with units with or without
economizers and it is recommended that both units be
equipped alike.
The MC4000 controller can be configured for alternative
(lead/lag/lead/lag) sequence, which is default setting. It
can be changed to non-alternating (lead/lead/lag/lag)
sequence as required for special applications or user
preference.
The MC4000 can be equipped with one of two alarm
boards, and these can be factory-installed or installed at
any time in the field if so desired.
Should the base controller alone be initially installed, it
is easily upgradeable by simple snap-in, plug-in field
installation of either one of the alarm boards, requiring
only the connection of the building alarm circuitry to the
alarm boards. Form C dry contact alarm relays are used,
offering both NO and NC switching to meet the user’s
specific alarm protocol, providing complete flexibility to
meet any user's requirements. All alarm actuations are
individually indicated on the controller front panel.
There is an Ethernet based remote communication
option that can be either factory or field installed. See
section on Communication Module.
