The ZXM2 Expansion Module for the UZC4 series is pictured above. A
total of nine (9) ZXM2's can be connected to the UZC4 to create a 22 ZONE
system! The modules are housed and linked together via a factory supplied
10 conductor BUS CABLE and a unique Expansion Header Card. The
UZC4 expands by connecting factory assembled Expansion Systems
such as the ZXM2A, ZXM4A and ZXM6A that are pre-wired and
configured for you at the factory. The UZC4 connects to these housed
expansion assemblies via a flexible 20" long bus cable. Each Expansion
module has a set of address switches that must be set properly to allow the
UZC4 to recognize each expansion module in the correct order. Note the
"STATUS" LED provided on every Expansion Module to indicate
active micro-processor operation. There are also two "DAMPER"
LED's provided to indicate which damper(s) are energized open or
closed. Next to each Damper and Thermostat terminal block is a blank
white square, where the "Zone Number" can be written to easily identify it as
a new expanded zone. These blocks will be filled in for you at the factory
when a UZC 6 zone, 8 zone, 10 zone or higher has been ordered. The ZXM2
address switches will also be factory set for you. Note the same multi-input
thermostat terminals are supplied on the ZXM2 as are supplied on the
UZC4 Main Module. Most Important of all is to note the MXR & MXC
Damper Motor Power Input Block. The ZXM2 Expansion Module is
powered via the Bus Cable from the UZC4, but the power for the
dampers must be provided by a separate transformer and is isolated
from the module. This allows great freedom to connect as many dampers
as the 2.5 amp thermal breaker can handle. See page 19 for damper motor
power supply details. Make sure to read the ZXM2 Technical Bulletin for
the proper cabling scenarios and zone address settings for your
system or refer to the chart on the right.

All Expansion module
Dip switch banks must
be set correctly for
proper zone address
identification. The 1st
expansion module
would be zones 5 & 6.
The 2nd expansion
module would be zones
7 & 8. The 3rd
expansion module
would be zones 9 & 10.
And so on up the line
for a total of 22 zones.
The switches are set
for you at the factory
unless you are
expanding the system
in the field. It is a good
idea to check them
anyway.
