The Honeywell 671159 thermostat subbase, off-heat-auto-cool switch has been used in many different applications. The 671159 datasheet provides information that can be used to determine the best application of the product. For example I found out at the datasheet that the minimum air flow rate is 800 CFM and I am planning to put it in a 16 X 20 unvented basement room with an 8 foot ceiling so I know it has enough air flow to keep the room cool.

A built-in off-heat-auto-cool switch reduces energy consumption by eliminating unnecessary cooling at night or when rooms are unoccupied. Fan switch has an on/off temperature control -- designed for use with air movement systems. 24 volts, single pole 4 wire grounded switching system.
