Control Options
Force–Flo cabinet heaters are available with four different control options:
• Manual three-speed fan switch
• Tracer ZN.010
• Tracer ZN.510
• Tracer ZN.520
Manual Fan Mode Switch
Model Number Digit 30 = A and Digit 31 = D or K
The manual fan mode switch is a four-position switch (off, high, medium, low) that
allows manual fan mode selection. The unit-mounted option (digit 31 = D) operates on
line voltage. The wall-mounted option (digit 31 = K) is low-voltage and has three 24 volt
relays using a factory-wired transformer and relays to control the fan motor.
Tracer
®
Controls
The Tracer family of controllers (ZN.010, ZN.510, and ZN.520) offer the combined
advantages of simple and dependable operation with the latest Trane-designed
controller. Standard control features include options normally available on more
elaborate control systems. All control options are available factory-configured or can
be field-configured using Rover
™
service software. For more detailed information, refer
to the Trane publication,
CNT-IOP-1 or CNT-IOP-2.
Tracer ZN.010
Model Number Digit 30 = E
Tracer ZN.010 is a stand-alone microprocessor controller.
Tracer ZN.510
Model Number Digit 30 = F
ZN.510 can be used as either a stand-alone or communicating microprocessor
controller.
Tracer ZN.520
Model Number Digit 30 = G
The ZN.520 controller can be used in a stand-alone application or as part of a Trane
Integrated Comfort
™
System (ICS).
In the stand-alone configuration, ZN.520 receives operation commands from the zone
sensor. The zone sensor module is capable of transmitting the following information to
the controller:
• Timed override on/cancel request
• Zone setpoint
• Current zone temperature
• Fan mode selection (off-auto-high-med-low)
For optimal system performance, Force–Flo units can be linked to an Integrated
Comfort™ System (ICS) building automation system controlled by Tracer Summit
®
.
The controller is connected directly to the Summit control panel via a twisted pair
communication wire, requiring no additional interface device (i.e., a command unit).
The Trane ICS system can monitor or override ZN.520 control points. This includes
such points as temperature and output positions.
Rover
™
Service Software
This windows-based software package option allows field service personnel to easily
monitor, save, download, and configure Tracer controllers through a communication
link from a portable computer. When connected to the communication link, Rover can
view any Tracer controller that is on the same communication link.
