Configuration

Trane configures the Tracer® VV550/VV551 controllers at the factory. Controller
configuration parameters can be modified in the field, as necessary, using the Rover
service tool. Topics in this chapter consist of:

Parameter Configurations

The control will not run normally without a complete set of all configuration data.
However, there is a small set of functions that do not require configuration. All other
functions require the complete set of valid configuration data. An invalid set of
configuration data generates a configuration diagnostic with a reported alarm message
of invalid unit configuration.

lists details that must be considered when configuring a Tracer VV550/VV551
Detail to consider
• Single duct
• Series fan powered
• Parallel fan powered
• Electric reheat (local and/or remote)
• Hot water reheat (local or remote)
Feature that is always present:
• Modulating air valve - single duct
Optional features that may or may not be present:
• Binary input (normally open, normally closed, or not present)
• Space temperature
• Space setpoint
• Primary/discharge air temperature
• Occupancy/generic binary input
• Fan
• Local or remote reheat
• Space temperature control (STC)/single duct
• Ventilation flow control (VFC)/single duct
• If reheat is present, a discharge air temperature sensor is required
• Flow tracking (FT)/single duct
• Does not support the bypass air valve on VariTrac
• Dual duct boxes are not supported directly. Two controllers and supporting logic are
required to coordinate controller operation
