Control Options
Force-Flo cabinet heaters are available with four different control options:
• Manual three-speed fan switch
• Tracer ZN010
• Tracer ZN510
• Tracer ZN520
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 (Tracer ZN010, ZN510, and ZN520) 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 ZN010
Model number digit 30 = E
Tracer ZN010 is a stand-alone microprocessor controller.
Tracer ZN510
Model number digit 30 = F
Tracer ZN510 can be used as either a stand-alone or communicating microprocessor
controller.
Tracer ZN520
Model number digit 30 = G
Tracer ZN520 controller can be used in a stand-alone application or as part of a Trane
Integrated Comfort
™
System (ICS).
In the stand-alone configuration, Tracer ZN520 receives operation commands from the
zone sensor. The zone sensor module is capable of transmitting the following informa-
tion 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 Tracer 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 Tracer ZN520 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 ZN controllers through a communication
link from a portable computer. When connected to the communication link, Rover can
view any Tracer ZN controller that is on the same communication link.
