Johnson Controls TMZ1600 Installation Instructions Manual

Installation Instructions
Issue Date April 12, 2006

Room Sensor with LCD Display (TMZ1600)

Application

The TMZ is compatible with Unitary (UNT) controller
and Variable Air Volume (VAV) (Revision D or later)
controller and with the VAV for Modular Assembly
(VMA1400 Rev. C00 or later and all VMA1200s). Use
HVAC PRO Release 8.01 or later to configure the
UNT, VAV, and VMA for use with the TMZ. Refer to
the Technical Data section for details.

The TMZ connects to the controller via an 8-pin phone
jack cable assembly that provides Zone Bus, sensor,
and power supply connections.

When the TMZ is used with a compatible
Johnson Controls digital controller, verify proper
system operation using a Zone Terminal Unit (ZTU), a
laptop computer with CBLPRO and HVAC PRO
software, or a Palm™ compatible handheld interface
with VMA Balancing Tool (VBT) software.

Both the ZTU and CBLPRO plug into the 6-pin phone
jack on the bottom of the TMZ to access the Zone bus.
