FEATURES

• Designed for new or existing system installations,
the MN50 controllers provide control for: unit
ventilators; heat pumps; fan coils; and packaged
rooftops.

• Conforms to the LonMark guidelines.

• HVAC interoperability achieved through use of
LonMark HVAC profiles.

• A complete, custom application can be designed
for each controller, using WorkPlace Tech Tool.

• Controllers are field programmable, using
WorkPlace Tech Tool, but controllers with satellite
profiles are especially suited for a broad range of
applications, providing solutions for your building
control needs.

• Capability to function in standalone mode or
as part of a
communications network.

• Multiple controllers on a LonWorks FTT network
create a complex network of controllers for
virtually any building control need.

• Proportional (P), Proportional Plus Integral (PI),
and Proportional Plus Integral and Derivative (PID)
control for cooling and heating.

• Onboard LED indication without cover removal.

• Plenum-rated enclosure allows direct mounting in
plenum.

LonWorks TP/FT-10 Free Topology

COMMUNICATIONS

Lon Works Networks

A LonWorks communications network uses a
TP/FT-10 Free Topology configuration. Controllers
on a

LonWorks network can communicate with each
other in a peer-to-peer fashion. A LonWorks network
has a communications speed of 78kbps, using
unshielded, twisted-pair cabling, with connections
that are not polarity sensitive.

S-Link

The Sensor Link (S-Link) communications wiring
provides power and a communication interface for an
MN-Sx TAC I/A Series MicroNet sensor. The various
MN-Sx sensors can provide room temperature,
room humidity, setpoint adjustment, and occupancy
override. This connection uses two-wire, unshielded
cable and is not polarity sensitive. Maximum wire
length allowed between a controller and a TAC I/A
Series MicroNet Sensor is 200ft (61m).
