Product Overview
The Tracer MP501 controller is a configurable, multi-purpose controller used to provide direct-digital control for heating, ventilation, and air conditioning (HVAC) equipment.
The controller can operate as a stand-alone device or as part of a building automation system (BAS). Communication between the controller and a BAS occurs via a LonTalk Comm5 communication link.
The Tracer MP501 provides a single control loop with the following output types: 2-stage, tri-state modulating, and 0–10 Vdc analog. The controller can be configured in two possible modes: Space Comfort Controller (SCC) or generic.
In SCC mode, the Tracer MP501 conforms to the LonMark SCC profile and controls space temperature to an active setpoint.
SCC mode supports the following applications:
• Heating control loop
• Cooling control loop
• Two-pipe heat/cool automatic changeover using a communicated water loop temperature
In generic mode, the Tracer MP501 provides control flexibility in a variety of applications that do not necessarily follow a LonMark profile. The control loop accepts inputs of the following types: temperature, pressure, flow, percent, or parts per million (ppm).
Generic mode supports many applications including:
• Fan speed control based on duct static pressure
• Pump speed control based on water differential pressure or flow
• Humidifier control based on space or duct relative humidity
Inputs and Outputs
Tracer MP501 inputs and outputs include:
• Analog inputs
– SCC mode; zone temperature, zone temperature setpoint
– Generic mode: 4–20 mA input
• Binary inputs
– SCC mode: 0ccupancy
– Generic mode: enable/disable
• Outputs
– 2-stage, tri-state modulation, or 0–10 Vdc analog
– SCC mode: fan on/off
– Generic mode: interlock device on/off (follows the enable/disable binary input)
• Generic point
– For use with a Tracer Summit building automation system: binary input (shared with occupancy/enable)
Generic inputs pass information to the building automation system. They do not directly affect the operation of the Tracer MP501 outputs.

Inputs and Outputs
Features
Easy Installation
The Tracer MP501 is suitable for indoor mounting in a variety of locations. Clearly labeled screw terminals ensure that wires are connected quickly and accurately. A compact enclosure design simplifies installation in minimal space.
Flexible Control
Using a single proportional, integral, and derivative (PID) control loop, the Tracer MP501 controller controls an output based on a measured input value and a specified setpoint. The output can be configured as a 2-stage, a tri-state modulating, or a 0–10 Vdc analog signal to control to the active setpoint.
Adjustable PID Loop
The Tracer MP501 provides a single control loop with adjustable PID control parameters, which allows control to be customized for a variety of applications.
Interoperability
In SCC mode, the Tracer MP501 conforms to the LonMark SCC profile. In generic mode, the controller does not conform to a specific LonMark profile, but supports standard network variable types (SNVTs). Both modes communicate via the LonTalk protocol. This allows the Tracer MP501 to be used with a Trane Tracer Summit system as well as other building automation systems that support LonTalk.
Occupied/Unoccupied Operation
Available in SCC mode only, the occupancy input works with a motion (occupancy) sensor or a time clock. A communicated value from a building automation system can also be used. The input allows the controller to use unoccupied (setback) temperature setpoints.
Control Interlock
Available in generic mode only, the interlock input works with a time clock or other binary switching device to enable or disable the controller process. When disabled, the control output is driven to a configurable (0–100%) default condition.
Continuous or Cycling Fan Operation
Available in SCC mode only, the fan can be configured to run continuously or cycle on and off automatically during occupied operation. The fan will always cycle in unoccupied mode.
Timed Override
Available in SCC mode only, the timed override function for after-hours operation allows users to request unit operation by the touch of a button on the zone temperature sensor. The override timer is configurable with a range of
0–240 minutes. Additionally, users can press the Cancel button at any time to place the unit back into unoccupied mode.
Manual Output Test
Pressing the Test button on the controller exercises all of the outputs in sequence. This feature is an invaluable troubleshooting tool that does not require a PC-based service tool.
Peer-to-peer Communication
The Tracer MP501 can share data with other LonTalk-based controllers. Several controllers can be bound as peers to share data such as setpoint, zone temperature, and heating/cooling mode. Space temperature control applications having more than one unit serving a single large space can benefit from this feature, which prevents multiple units from simultaneously heating and cooling.

Network Architecture
The Tracer MP501 can operate on a Tracer Summit building automation system (refer to Figure 1 below), on a peer-to-peer network (refer to Figure 2, p. 9), or as a stand-alone device. The Tracer MP501 can be configured using the Rover service tool for Tracer controllers or any other PC-based service tool compliant with the EIA/CEA-860 standard. This tool can be connected to a communication jack on a zone temperature sensor or at any accessible location on the LonTalk Comm5 communication link.
