About This Cross Reference/Selection Guide
Heat pumps require thermostats with special features. This Cross Reference/Selection Guide contains information about
all aspects of selecting a Honeywell replacement thermostat for any heat pump application. Table 1 shows a list of the
Honeywell TRADELINE® and SUPER TRADELINE® OS numbers and their specifications. Immediately following the
table are more detailed descriptions and related application information. In this section you will find additional
information explaining features and requirements that are unique to heat pump thermostat applications. Following the
general information section are the internal schematics, wiring diagrams, and sequence of operation information for the
electronic thermostats. The Thermostat Manufacturer Cross Reference is listed next. Finally, there is the heat pump
manufacturer cross reference, including tips on how to use it. This cross reference, which is organized alphabetically by
equipment or thermostat manufacturer, provides the needed information to select and wire any Honeywell heat pump
thermostat in new installations and replacement applications.
