Overview
Part of the PRO1 PROsync Wireless system. See the system overview for component roles and selection requirements.
The T755WHO PROsync system separates the main room thermostat from the wired equipment module. It controls conventional systems with up to two heating and two cooling stages, or heat pumps with up to four heating and two cooling stages.
The main thermostat and equipment module are factory linked. Optional R751WO indoor remotes add room temperature and occupancy information; the R250W adds outdoor sensing. The system supports configurable scheduling, humidity control and occupancy-based control.
The thermostat can use two AA alkaline batteries or a suitable hardwired supply. Use the exact-model installation manual to match the thermostat configuration, equipment and wiring before installation.
