Component Descriptions - Zonex ZonexCommander Installation Manual

The ZonexCommander automates and networks 1-80 HVAC units,
providing remote communication with all RTUs or splits in your
system. The ZonexCommander eliminates the need to continually set
and reset multiple programmable thermostats located throughout your r
building. ZonexCommander bridges the gap between ineffective
stand-alone thermostats and expensive and complex automation systems.
Please review integral components of the Zonex Systems below.
COMMAND CENTERS
The Command Center is a microprocessor based digital communicating
controller. Each Command Center supports up to 20 devices (thermostats
and RLYCOM relay modules).
A unique Command Center exists for each communicating Zonex System: :
ZonexCommander
ZonexCommander (Plus)
The Command Centers communicate with the computer through the RS-232
link, and communications with thermostats or devices communicate
through the RS-485 link using a daisy chained two-wire twisted pair
(Belden 8740).
Each Command Center maintains Day, Date, Time and Year with battery
backup. All Occupied, Unoccupied and Vacation schedules, device name
tags and addresses are programmed into non-volatile memory, which is
not affected by power interruptions.
The Command Centers are powered by dedicated 24vac 40va, field
supplied transformers. Each Command Center must have its own
transformer power supply.
ZONEXCOMMANDER COMMAND CENTER
Part #CETCIP
CETCIP – ZonexCommander Communications Package with TCIP
network device, for 20 communicating devices.
COMCIP – Command center with TCIP – adds 20 additional com-
municating devices for larger systems.
ZONEX COMPONENT DESCRIPTIONS
ZONEXCOMMANDER (PLUS) COMMAND CENTER
ZPTCIP – ZonexCommander (Plus) Communications Package with
TCIP network device for internet communications, for 1-4 RMODs
with 20 communicating devices. Includes system operating software.
CZNXIP Command Center with TCIP – supports 4 additional
RMODs and another 20 additional communicating devices.
ZonexCommander (Plus) is designed to provide centralized control
for multiple zoned HVAC systems. Each Command Center supports up
to 20 devices (ModStat, MODS2, DIGICOM thermostats and
RLYCOMs). Each ZPTCIP Command Center controls up to four
RMOD controllers, each controlling one HV AC unit. CZNXIP Com-
mand Centers via TCIP device provide expansion capability to
support up to 16 HVAC units with 80 zones. The thermostats are allo-
cated to the RMOD controller through ZonexCommander (Plus)
software.
RMOD – UNIT RELAY MODULE
For use with ZonexCommander (Plus) systems only
Each Command Center can support 4 RMODs. Each Universal RMOD
controls a zoned GE or
HP unit with on-board
capacity control. The
RMOD communicates
with the Command
Center and thermostats
assigned to that RMOD.
Each thermostat can
send a heat or cool call
to the RMOD. The RMOD
polls the number of heat
or cool calls every
minute and energizes
the unit based on our
control algorithm of
first call first served, majority wins on changeover. .
THERMOSTATS
The DIGICOM and DIGIHP thermostats are used to control stand-
alone Gas Electric (2H/2C) or Heat Pump (3H/2C) HVAC systems.
