The Aqua-Air Sapphire TSV and TWS Series Direct Expansion (D/X) Systems have been designed specifically to operate either split systems or self-contained  units. These systems will usually have a compressor, revising valve,  seawater pump and fan motor(s). All of these components can be regulated by these thermostats.   
The only difference between the TSV and the TWS models is the display head appearance. The TSV has a Vimar®  brand bezel surrounding the display and button portion of the display head. The TWS was designed as a retrofit for the older Aqua-Air TW-2000 digital thermostat. The TWS display head is the same size as the older TW-2000. Both controls operate in exactly the same way.
