The T6380 series of electronic fan coil thermostats provide precision line voltage control of fan-forced Heating, Ventilating and Air Conditioning equipment. Models are available for the cooling-only, manual heat-cool changeover, or remote heat cool changeover systems. Hydronic source heat-cool systems may be two or four-pipe configurations with 0, 1, or 2 valves. Fan control options include constant, cycled, or user selectable “On-Auto” operations. Manual fan speed selection is standard. All models feature an “Off” switch.

MOUNTING
Internal schematic and external wiring connections are shown in Fig. 2a through Fig. 8c. Wiring connections may be made to the 8 position screw terminal block with 1- 14 AWG, or 2- 18 AWG, solid or stranded copper wires
As the temperature changes, the thermostat makes to open a valve and/or power a blower to provide heating or cooling. The speed at which the air is circulated is controlled by the FAN switch. Continuous (ON) or intermittent (AUTO) fan operation is determined by model number
